Guidance for using fab to programmatically manage Fabric & Power BI service
- Install via
uv tool install ms-fabric-cli(getuvviawinget install uvorbrew install uv) - Fabric CLI is for working with the Cloud environment and not local files; it works with Power BI Pro, PPU, or Fabric; you DO NOT need a Fabric SKU to use the Fabric CLI
- Keep
fabcurrent: check the installed version against the latestms-fabric-clirelease and upgrade withuv tool upgrade ms-fabric-cliunless the user has pinned a specific version. Discover commands and flags withfab --helpandfab <command> --helprather than hard-coding behavior; the CLI surface changes regularly
[!IMPORTANT] Any time you encounter errors, user preferences or learnings when using the Fabric cli, ALWAYS note these down in the user memory rules, i.e.
.claude/rules/fabric-cli.mdfor future improvement. This is ONLY for generic learnings and not for item- or task-specific learnings.
When to use this skill
- Use whenever the user mentions "Fabric" or "Power BI"
- Use when user asks about Power BI workspaces, deployment, tenants, publishing, download, permissions, or data
Critical general rules
- IMPORTANT: The first time you use
fabrun check that it is up to date to the latest version (upgrade withuv tool upgrade ms-fabric-cliunless the user has pinned a version) and runfab auth status; If user isn't authenticated, ask them to runfab auth login - Always use
fab --helpandfab <command> --helpthe first time you use a command to understand its syntax - You must search the skill /references/ for relevant reference files that explain certain commands, examples, scripts, or workflows before you start using
fab - Before first use, ask the user if they have Fabric admin access, sensitivity labels or DLP policies, any API restrictions, or preferences for Fabric/Power BI API usage; remind user to add this to memory files
- If workspace or item name is unclear, ask the user first, then verify with
fab lsorfab existsbefore proceeding - Ensure that you avoid removing or moving items, workspaces, or definitions, or changing properties without explicit user direction
- IMPORTANT: Before any operation that consumes capacity units (creating items, running notebooks, pipelines or refreshes, large queries, Copilot, preview items such as Plan, Ontology or Graph, anything scheduled), estimate its CU-hours and its impact on the capacity, and get explicit user approval when the charge is flat or per session, exceeds a quarter of the capacity's daily CU-hours, recurs, cannot be estimated, or the capacity already throttles; a user naming a feature is not consent to its cost. See Capacity cost and capacity-cost.md
- If a command is blocked in your permissions and you try to use it, stop and ask the user for clarification; never try to circumvent it
- Create output directories before export:
fab exportdoes not create intermediate directories;mkdir -pthe output path first or the command fails with[InvalidPath]
Capacity cost: estimate before acting
Bursting hides cost: operations finish fast and their CUs are smoothed into the next 5 to 64 minutes (interactive) or 24 hours (background). On a small F SKU one operation can use more than a day of capacity, and the carry forward then throttles every workspace on it until idle capacity pays it back, which on an F2 can take weeks.
- Check the capacity first:
fab ls .capacities -lfor SKU and state; the Monitoring hub capacity page for utilization, throttling and carry forward. Any carry forward means no headroom - Estimate the operation in CU-hours and EUR, and as a share of the SKU's daily budget (an F has 24 * n CU-hours a day; an F2 has 48)
- Know the flat charges: Plan (preview) bills 30-day sessions per user (Planner 847, Stakeholder 168, Viewer 37 CU-hours); creating and editing a plan by REST was billed as a Stakeholder session (168 CU-h), and a session cannot be ended or refunded
- Pausing (
fab stop) bills the whole carry forward at once and clears throttling; scaling up burns it down faster at a similar total cost - Full thresholds, formulas, known charges and where to see what an operation cost: capacity-cost.md
Use -f (force) for non-interactive use
The fab CLI prompts for confirmation, so you you must always append -f to prevent this UNLESS sensitivity labels are enabled, in which case you must ask the user. Do this for the commands:
fab get -q "definition"; sensitivity label confirmationfab export; sensitivity label confirmationfab import; overwrite confirmationfab cp/fab cp -r; overwrite and sensitivity label confirmationfab rm; delete confirmationfab assign/fab unassign; capacity/domain assignment confirmationfab mv; rename/move confirmation
Quickstart guide
You must read and understand the common list of operations with simple examples
- Check the commands, syntax, and auth status:
fab --helpandfab auth status - Check if the item exists if the user gave the workspace and item name:
fab exists "spaceparts-dev.Workspace/spaceparts-otc-full.SemanticModel" - Find an item by name across every workspace the user can see:
fab find 'sales' -P type=Report -l(substring on name, description, workspace;-P type=to filter,-lfor ids;-q '<jmespath>'for client-side filter/projection). For governance workflows that need last visit / last refresh / owner / storage mode / capacity SKU, usescripts/search_across_workspaces.py; see workspaces.md for the delta. - Find the workspace:
fab ls - Find the item:
fab ls "Workspace Name.Workspace" - Check the commands for that item:
fab descto get itemTypesfab desc .<ItemType>for commands i.e.fab desc .SemanticModel
- What's in that item; what's it for; what is it?:
- Full TMDL definition:
fab get "spaceparts-dev.Workspace/spaceparts-otc-full.SemanticModel" -q "definition" -f - Search a specific measure / table / column:
fab get "ws.Workspace/Model.SemanticModel" -q "definition" -f | rga -i "Sales Amount" - Retrieve AI instructions / AI schema:
python3 scripts/get_semantic_model_ai_metadata.py "ws.Workspace/Model.SemanticModel" --instructions-out instructions.md --schema-out schema.json
- Full TMDL definition:
- Get files, tables, or table schemas:
- List lakehouse files:
fab ls "ws.Workspace/LH.Lakehouse/Files" - List lakehouse tables:
fab ls "ws.Workspace/LH.Lakehouse/Tables" - Table schema:
fab table schema "ws.Workspace/LH.Lakehouse/Tables/gold/orders"
- List lakehouse files:
- Query data (always prefer the wrapper scripts over raw
fab api/duckdb/sqlcmd; they resolve IDs, hosts, and auth for you):- Semantic model (DAX):
python3 scripts/execute_dax.py "ws.Workspace/Model.SemanticModel" -q "EVALUATE TOPN(10, 'Orders')" - Lakehouse SQL endpoint, warehouse, or SQL database (T-SQL):
python3 scripts/query_sql_endpoint.py "ws.Workspace/LH.Lakehouse" -q "SELECT TOP 10 * FROM dbo.orders"; afabric-sqlMCP is only present if the user registered one. See querying-data.md - Lakehouse or warehouse Delta over OneLake (DuckDB):
python3 scripts/query_lakehouse_duckdb.py "ws.Workspace/LH.Lakehouse" -q "SELECT * FROM tbl LIMIT 10" -t gold.orders
- Semantic model (DAX):
- Set properties for an item or workspace:
fab set "ws.Workspace/Item.Notebook" -q displayName -i "New Name"orfab set "ws.Workspace" -q description -i "Production environment" - Review or manage permissions:
- Item ACL:
fab acl ls "ws.Workspace/Model.SemanticModel"thenfab acl set "ws.Workspace/Model.SemanticModel" -I user@contoso.com -R Read - Workspace roles:
fab acl ls "ws.Workspace"thenfab acl set "ws.Workspace" -I user@contoso.com -R Member - Setting up a service principal for automation instead of a human identity: service-principals.md - creation via az CLI, the workspace-role-plus-tenant-setting-group double requirement, and how to authenticate
fabas it
- Item ACL:
- Deploy items to Fabric:
fab import "ws.Workspace/New.Notebook" -i ./local-path/Nb.Notebook -f - Download items from Fabric:
fab export "ws.Workspace/Nb.Notebook" -o ./backup -f(alwaysmkdir -p ./backupfirst) - Copy or move items between workspaces:
fab cp "dev.Workspace/Item.Notebook" "prod.Workspace" -forfab mv "ws.Workspace/Old.Notebook" "ws.Workspace/New.Notebook" -f - Open item in Fabric via browser:
fab open "spaceparts-dev.SpaceParts/Amazing Report.Report" - Using Fabric or Power BI APIs:
fab api -A powerbi "groups/<ws-id>/datasets/<model-id>/refreshes" -X post -i '{"type":"Full"}'orfab api "workspaces/<ws-id>/items" - Using Azure CLI (advanced) when Fabric CLI doesn't suffice:
- T-SQL over any SQL-capable item ; use
scripts/query_sql_endpoint.py(reusesaz loginviaActiveDirectoryAzCli; full walkthrough in querying-data.md) - Pass a Key Vault secret to a consumer without ever reading, echoing, or persisting it:
az login --service-principal -u <appId> -t <tenantId> --password "$(az keyvault secret show --vault-name <vault> --name <secret> --query value -o tsv)"; command substitution pipes the secret directly into the child process arg list, never stdout, a file, or a named shell variable - Full fab-vs-az decision matrix: fab-vs-az-cli.md
- T-SQL over any SQL-capable item ; use
Essential Concepts
For information about any concepts related to Power BI or Fabric you must search or fetch via the microsoft-learn MCP server (or the pbi-search CLI as an alternative) and ask the user questions with the AskUserQuestion tool; NEVER guess or make assumptions.
Workspaces
- Workspaces are containers for items like Notebooks (and other ETL items), Lakehouses (and other data items), SemanticModels, Reports (and other consumption items), and OrgApps.
- Workspaces can be assigned to different things:
- Deployment Pipelines for lifecycle management (Dev, Test, Prod, etc.)
- Domains for governance and tenant structuring
- Capacities for licensing and resources (Fabric or Premium capacities only; PPU and Pro work differently)
- Git repositories for Source Control via Git integration
Key Patterns
Pay special attention to each of the following areas when using the Fabric CLI
Path Format
Fabric uses filesystem-like paths with type extensions:
"WorkspaceName.Workspace/ItemName.ItemType"
You must quote paths with spaces and punctuation:
"Workspace Name.Workspace/Semantic Model Name.SemanticModel"
For lakehouses this is extended into files and tables:
WorkspaceName.Workspace/LakehouseName.Lakehouse/Files/FileName.extension or /WorkspaceName.Workspace/LakehouseName.Lakehouse/Tables/TableName
For Fabric capacities you have to use fab ls .capacities
Examples:
"Production Workspace.Workspace/Sales Report.Report"Data.Workspace/MainLH.Lakehouse/Files/data.csvData.Workspace/MainLH.Lakehouse/Tables/dbo/customers
Common Item Types
.Workspace- Workspaces.SemanticModel- Power BI datasets.Report- Power BI reports.Notebook- Fabric notebooks.DataPipeline- Data pipelines.Lakehouse/.Warehouse/.SQLDatabase- Data artifacts.SparkJobDefinition- Spark jobs.AISkill- Fabric Data Agents.MirroredDatabase/.MirroredWarehouse- Mirrored databases.Environment- Spark environments.UserDataFunction- User data functions
Full list: You must use fab desc or fab desc .<ItemType> to check syntax and types if the user asks about an item type not listed above.
JMESPath Queries
Filter and transform JSON responses with -q:
# Get single field
-q "id"
-q "displayName"
# Get nested field
-q "properties.sqlEndpointProperties"
-q "definition.parts[0]"
# Filter arrays
-q "value[?type=='Lakehouse']"
-q "value[?contains(name, 'prod')]"
# Get first element
-q "value[0]"
-q "definition.parts[?path=='model.tmdl'] | [0]"
Using fab api
fab has an api escape hatch that lets you use any API even if it doesn't have primary commands.
Variable Extraction Pattern
To use fab api you need item IDs. Extract them like this:
WS_ID=$(fab get "ws.Workspace" -q "id" | tr -d '"')
MODEL_ID=$(fab get "ws.Workspace/Model.SemanticModel" -q "id" | tr -d '"')
# Then use in API calls
fab api -A powerbi "groups/$WS_ID/datasets/$MODEL_ID/refreshes" -X post -i '{"type":"Full"}'
Admin APIs (Requires Admin Role)
Don't use admin commands or APIs if the user doesn't have Admin access. Here's some examples:
# Find semantic models by name (cross-workspace)
fab api "admin/items" -P "type=SemanticModel" -q "itemEntities[?contains(name, 'Sales')]"
# Find all notebooks
fab api "admin/items" -P "type=Notebook" -q "itemEntities[].{name:name,workspace:workspaceId}"
# Find all lakehouses
fab api "admin/items" -P "type=Lakehouse"
# Common types: SemanticModel, Report, Notebook, Lakehouse, Warehouse, DataPipeline, Ontology
For full admin API reference (cross-workspace discovery, tenant settings read/update, capacity/domain/workspace overrides, activity events): admin.md
Error Handling & Debugging
# Show response headers
fab api workspaces --show_headers
# Verbose output
fab get "Production.Workspace/Item" -v
# Save responses for debugging
fab api workspaces -o /tmp/workspaces.json
Common workflows
These are the most common workflows you'll encounter in Fabric
Finding or exploring workspaces, items, or metadata
| Command | Purpose | Example |
|---|---|---|
fab ls |
List workspaces / items | fab ls "Sales.Workspace" -l |
fab exists |
Check if a path exists | fab exists "Sales.Workspace/Model.SemanticModel" |
fab get |
Get item details | fab get "Sales.Workspace" -q "id" |
fab desc |
Supported commands per type | fab desc .SemanticModel |
Flags:
-l(long listing)-a(show hidden items)-q(JMESPath filter)-v(verbose output)-o(save response to file)
Fabric discovery follows a drill-down pattern:
- Browsing:
- List workspaces:
fab ls - List items in a workspace:
fab ls "ws.Workspace" -l - Confirm a path exists:
fab exists "ws.Workspace/Item" - Check what commands an item type supports:
fab desc .<ItemType>
- List workspaces:
- Inspection:
- Get item details:
fab get "ws.Workspace/Item" - Pull a single field:
fab get "ws.Workspace" -q "id"
- Get item details:
- Cross-workspace search:
- Routine search across name, description, workspace:
fab find '<text>' -P type=<Type> -l - Governance fields not in
fab find(last visit, last refresh, owner, storage mode, capacity SKU, Copilot readiness):scripts/search_across_workspaces.py; see workspaces.md for the delta - Downstream reports for a given model:
scripts/get-downstream-reports.py - Tenant-wide admin APIs: admin.md
- Routine search across name, description, workspace:

Querying data
| Command | Purpose | Example |
|---|---|---|
fab get -q "definition" |
Get model schema | fab get "ws.Workspace/Model.SemanticModel" -q "definition" -f |
fab api -A powerbi |
Execute DAX | fab api -A powerbi "groups/<ws-id>/datasets/<model-id>/executeQueries" -X post -i '{"queries":[{"query":"EVALUATE..."}]}' |
fab ls |
Browse files / tables | fab ls "ws.Workspace/LH.Lakehouse/Files" |
fab table schema |
Lakehouse table schema | fab table schema "ws.Workspace/LH.Lakehouse/Tables/sales" |
fab cp |
Upload / download OneLake file | fab cp ./local.csv "ws.Workspace/LH.Lakehouse/Files/" |
duckdb + delta_scan |
Query Delta tables (requires DuckDB) | duckdb -c "... delta_scan('abfss://<ws-id>@onelake.../<lh-id>/Tables/schema/table')" |
duckdb + read_csv/json |
Query raw files (requires DuckDB) | duckdb -c "... read_csv('abfss://.../Files/data.csv')" |
Flags:
-A fabric|powerbi|storage|azure(API audience)-X get|post|put|delete|patch(HTTP method)-i(JSON body or file)-f(skip sensitivity prompt on definition pulls).
Fabric exposes three query paths depending on the source; always prefer the wrapper scripts -- they resolve IDs, hosts, and auth for you:
- Semantic models (DAX):
- Find model fields first:
fab get "ws.Workspace/Model.SemanticModel" -q "definition" - Query:
scripts/execute_dax.py
- Find model fields first:
- Lakehouses / Warehouses via Delta over OneLake (DuckDB):
- Query a single table:
scripts/query_lakehouse_duckdb.py(usetblas a placeholder and pass-t schema.table) - Multi-table joins or raw files in
Files/: pass--sqlwith your owndelta_scan()/read_csv/read_json_autocalls - Optionally scaffold a Direct Lake model instead:
scripts/create_direct_lake_model.py
- Query a single table:
- Lakehouse SQL endpoint, Warehouse, or SQL Database (T-SQL):
- Use
scripts/query_sql_endpoint.py(sqlcmd; auto-detects host per item type, reusesaz loginviaActiveDirectoryAzCli) - The plugin ships no
fabric-sqlMCP; use one only if the user registered it themselves - Prefer either over DuckDB when you need
INFORMATION_SCHEMA,sys.*metadata, CTEs, or window functions - Full route priority: querying-data.md
- Use
Check references before writing queries:
Changing metadata or access (descriptions, tags, endorsement, properties, bindings, permissions)
| Command | Purpose | Example |
|---|---|---|
fab set |
Update property | fab set "ws.Workspace/Item" -q displayName -i "New Name" |
fab mv |
Rename / move item | fab mv "ws/Old.Notebook" "ws/New.Notebook" -f |
fab acl ls |
List permissions | fab acl ls "ws.Workspace" |
fab acl set |
Grant permission | fab acl set "ws.Workspace" -I <objectId> -R Member |
fab acl rm |
Revoke permission | fab acl rm "ws.Workspace" -I <upn> |
fab label set |
Set sensitivity label | fab label set "ws/Nb.Notebook" --name Confidential |
Flags:
-q <field>+-i <value>(set a single property)-I(object ID or UPN forfab acl)-R Admin|Member|Contributor|Viewer(role forfab acl set)-f(skip confirmation; ask user first if sensitivity labels are in play)
Metadata and access changes fall into a few groups:
- Properties (displayName, description, sensitivity config):
- Native update:
fab set "<path>" -q <field> -i "<value>" - Capture current state first so you can revert:
fab get -v -o /tmp/before.json
- Native update:
- Endorsement, certification, and tags (no first-class
fabcommands):- Patch via
fab apiwith item-specific endpoints - Tag workflow: tags.md
- Endorsement patterns: reference.md
- Patch via
- Folder placement:
- Move items between workspace subfolders: folders.md
- Access control and sensitivity labels:
- Grant / revoke:
fab acl set,fab acl rm - Set sensitivity label:
fab label set - Verify the principal first:
az ad user show - Never change permissions or labels without explicit user confirmation
- Grant / revoke:
- Bindings:
- Rebind a thin
.Reportto a different.SemanticModel: reports.md - Semantic model source rebinds (e.g. swap a lakehouse): semantic-models.md
- Rebind a thin

Working with workspaces
| Command | Purpose | Example |
|---|---|---|
fab mkdir |
Create workspace / item | fab mkdir "New.Workspace" -P capacityname=MyCapacity |
fab assign |
Attach capacity / domain | fab assign .capacities/cap.Capacity -W ws.Workspace -f |

Flags:
-P key=value(creation params forfab mkdir)-W(target workspace forfab assign/fab unassign)-r(recursive copy/move)-bpc(block on path collision forfab cp)-f(skip confirmation)
Workspace-scope operations fall into a few groups:
- Create and provision:
- Create workspace:
fab mkdir "<Name>.Workspace" -P capacityname=<cap> - Attach capacity or domain:
fab assign .capacities/<cap>.Capacity -W <ws>.Workspace - Planning context, create/get/set surface, large storage format, Spark pools, OneLake defaults, Git: workspaces.md
- Create workspace:
- Copy, fork, download:
- Duplicate a workspace in-tenant:
fab cp -r "dev.Workspace" "prod.Workspace" - Dry-run the source tree first:
fab ls "dev.Workspace" - Full local snapshot (items + lakehouse files):
scripts/download_workspace.py
- Duplicate a workspace in-tenant:
- Permissions:
- Inspect / grant / revoke:
fab acl ls | set | rm - Tenant-wide governance audit: use the
audit-tenant-settingsskill from thefabric-adminplugin

Executing or scheduling jobs (notebooks, notebook cells, pipelines, semantic model refresh)
| Command | Purpose | Example |
|---|---|---|
fab job run |
Run synchronously | fab job run "ws/ETL.Notebook" -P date:string=2025-01-01 |
fab job start |
Run asynchronously | fab job start "ws/ETL.Notebook" |
fab job run-list |
List executions | fab job run-list "ws/Nb.Notebook" |

fab api -A powerbi .../refreshes |
Trigger semantic model refresh | fab api -A powerbi "groups/<ws-id>/datasets/<model-id>/refreshes" -X post -i '{"type":"Full"}' |
Flags:
-P key:type=value(parameters, type isstring|int|bool)--id(job run ID)-w(wait on cancel)--timeout(overall timeout for synchronous runs)--polling_interval(status poll cadence)
Jobs map to different endpoints depending on item type:
- Notebooks and pipelines:
- Run synchronously:
fab job run "ws/ETL.Notebook" -P date:string=2025-01-01 - Run asynchronously:
fab job start "ws/ETL.Notebook" - Check status:
fab job run-status "ws/Nb.Notebook" --id <job-id> - List history:
fab job run-list "ws/Nb.Notebook" - Verify the REAL outcome: a job
Completedonly means the process finished -- a notebook can catch its own exception and exit a failure payload while still showingCompleted. Read its exit value, or usescripts/run_notebook_checked.py; details in notebooks.md - Python / PySpark kernels, Livy sessions, cell-level CRUD: notebooks.md
- Run synchronously:
- Semantic model refresh (not exposed as
fab job):- Trigger:
fab api -A powerbi "groups/<ws-id>/datasets/<model-id>/refreshes" -X post -i '{"type":"Full"}' - Check current run before starting a new one (409 if already running):
fab api -A powerbi "groups/<ws-id>/datasets/<model-id>/refreshes?\$top=1" - Enhanced refresh, incremental policies, partition targeting: semantic-models.md
- Trigger:
- Dataflow refresh:
- Gen1 and Gen2 have different endpoints: dataflows.md
- Scheduling:
- Per-item schedules via the scheduler API: notebooks.md, reference.md

Fabric admin operations (auditing, management)
| Command | Purpose | Example |
|---|---|---|
fab api "admin/items" |
Cross-workspace item search | fab api "admin/items" -P "type=SemanticModel" -q "itemEntities[?contains(name,'Sales')]" |
fab api "admin/workspaces" |
Workspace inventory | fab api "admin/workspaces" |
fab api "admin/tenantsettings" |

Flags:
-P key=value(query params, e.g.type=SemanticModel)-q(JMESPath filter)-X post+-i(write ops)--show_headers(inspectRetry-Afteron 429)
Admin-scope work is gated behind the Fabric / Power BI admin role. Confirm access first with fab api "admin/capacities" 2>&1 | head -5; if it errors, stop rather than retry.
Two entry points cover most admin tasks:
- Governance audits (tenant settings, delegated overrides, Entra SG scoping):
- Use the
audit-tenant-settingsskill from thefabric-adminplugin. It owns the curated metadata baseline, the audit + change-detection script, delegated-override enumeration, and the Entra SG investigation workflow. - Invoke it whenever the question combines tenant posture with group membership, override scope, or drift against the baseline.
- Use the
- Raw admin APIs (cross-workspace search, activity events, artifact access, item search):
- Patterns in admin.md
- Rate limit: 25 write requests / minute; honor
Retry-Afteron 429 - Print the exact command and wait for user confirmation before any destructive admin operation
Check references before admin work:
- admin.md
- permissions.md for workspace / item ACL exposure audits
Definitions and deployment (item definitions, deployment pipelines, git integration, cicd)
| Command | Purpose | Example |
|---|---|---|
fab get -q "definition" |
Read raw definition | fab get "ws/Model.SemanticModel" -q "definition" -f |
fab export |
Export item to local | fab export "ws/Nb.Notebook" -o ./backup -f |
fab import |
Import item from local | fab import "ws/Nb.Notebook" -i ./backup/Nb.Notebook -f |
fab cp |
Copy between workspaces | fab cp "dev/Item" "prod.Workspace" -f |
fab api "deploymentPipelines" |
Deployment pipelines API | fab api "deploymentPipelines" -q "value[]" |
Flags:
-o(output path forfab export)-i(input path or JSON body forfab import)--format(definition format for export / import)-f(skip overwrite and sensitivity prompts)
[!IMPORTANT] The poll interval is by far the biggest performance lever for any definition change. Creating or updating an item definition is a long-running operation (LRO): the API returns
202 Acceptedwith aRetry-After: 20header.fab import,nb create, andnb cell editwait roughly that long between status polls, so a notebook that the server finishes in ~1s takes them 25-60s. Neitherfabnornbexposes a knob to change that interval. For notebook definition changes, strongly preferscripts/deploy_notebook.py, which polls the LRO every ~0.3s (tunable via--poll-interval) and creates in ~1-2s or updates in place in ~1s. Auto-detects create vs update. When you must roll your own for another item type, the rule is the same: pollupdateDefinition/ create at ~0.3s, not the advertised 20s.python3 scripts/deploy_notebook.py "ws.Workspace/ETL.Notebook" -i ./ETL.Notebook # create or update in place
Every Fabric item has a serializable definition. Move definitions between environments depending on scope:
- Single item:
- Round-trip locally:
fab exportthenfab import(alwaysmkdir -pthe output directory first;fab exportdoes not create intermediate directories and fails with[InvalidPath]) - Same-tenant shortcut, no local hop:
fab cp "dev/Item" "prod.Workspace"
- Round-trip locally:
- Semantic model as PBIP (TMDL + blank report):
- Export the model with
fab export, create the report withpbir new report, then combine them withpbir report merge-to-thick; see import-download-deploy.md
- Export the model with
- Full workspace snapshot (items + lakehouse files):
- Backups, offline analysis, cross-tenant forks:
scripts/download_workspace.py
- Backups, offline analysis, cross-tenant forks:
- Promotion between Dev, Test, Prod:
- Fabric deployment pipelines API (covers all item types)
- Power BI pipelines API (Power BI items only, but finer-grained deploy flags like
allowPurgeData,allowTakeOver) - When to use each, selective deploy, LRO polling: deployment-pipelines.md
- Git integration (connect workspace to repo, branch, commit, update from git):
- Workspace git section in workspaces.md
Check references before deploying:
- import-download-deploy.md ; export / import / copy / move, PBIP round-trips, migration patterns, rebinding gotchas
- deployment-pipelines.md
- semantic-models.md
- reports.md
- paginated-reports.md
- notebooks.md
- workspaces.md

Gotchas
- IMPORTANT: DON'T try to use
fab lson items that aren't data items (.Lakehouse, .Warehouse, etc); usefab lsto find workspaces and items, and usefab getto look at definitions - ALWAYS Use the
-fflag when usingfab get,fab import,fab export, etc. as described above - ONLY fallback to
fab apiwhen a command doesn't exist - Definition changes feel slow but aren't:
fab import/nb create/nb cell edittake 25-60s to push a notebook definition only because they poll the LRO at the server'sRetry-After: 20. The work is ~1s. Usescripts/deploy_notebook.py(tight-polls at ~0.3s) for definition changes; the poll interval is the single biggest lever

- Lakehouses - Endpoints, file/table operations, OneLake paths
- Warehouses - Create, browse, query via DuckDB, load data
- SQL Databases - Create, browse, query via DuckDB, auto-mirroring
- Semantic Models - TMDL, DAX, refresh, storage mode
- Reports - Export, import, visuals, fields
- Paginated Reports - RDL upload, export-to-file, datasources, parameters
- Notebooks - Python/PySpark kernels, metadata, cell CRUD, Livy execution, scheduling
- Workspaces - Create, manage, permissions
- Permissions - Sharing and distribution, workspace roles, item permissions, apps, embed, B2B, deployment pipeline permissions, licensing and capacity SKUs
- Deployment Pipelines - CI/CD, deploy stages, selective deploy, LRO polling
- Dataflows - Gen1 and Gen2, refresh, publish, admin
- Dashboards - Tiles, clone (dashboards are not reports)
- Org Apps - Read-only API for distributed content packages
- Scorecards - Goals, check-ins, status rules (Preview API)
- Gateways - Datasources, credentials, dataset binding
- Folders - Organize items into folders via API; includes best practices for structuring workspaces
- Tags - Create, apply, and audit tenant/domain tags on items and workspaces via
fab api(no nativefab tagcommand) - Capacity cost - Estimate CU-hours and capacity impact before acting: SKU budgets, smoothing, throttling stages, carry forward and burndown, pause billing, known flat charges (Plan, Ontology, Copilot)
- fab vs az CLI - When to use which; capacity, networking, Key Vault, monitoring, CMK, CI/CD
- Admin APIs - Cross-workspace search, tenant operations, governance
- API Reference - Capacities, domains, misc API patterns
- Connections - Create, update, list connections programmatically; credential types (WorkspaceIdentity, SPN, Basic); OAuth2 limitations
- Service Principals - Create an SP with az CLI, grant it workspace access, clear the tenant-setting gate, authenticate
fabas it (real login vs env-token testing), rotation and teardown - Full Command Reference - All commands detailed
Scripts (scripts that you can execute):
- search_across_workspaces.py ; cross-workspace governance complement to
fab find(last visit, last refresh, owner, storage mode, capacity SKU, Copilot readiness); see workspaces.md for when to choose which - get-downstream-reports.py ; find all reports connected to a given semantic model across accessible workspaces (no admin required)
- execute_dax.py ; execute DAX queries against semantic models; output as table, csv, or json
- query_lakehouse_duckdb.py ; query lakehouse or warehouse Delta tables via DuckDB against OneLake (reuses
az login); output as table, csv, or json - query_sql_endpoint.py ; query lakehouse SQL endpoint, warehouse, or SQL database via
sqlcmd(reusesaz loginthroughActiveDirectoryAzCli); output as table, csv, or json - create_direct_lake_model.py ; create a Direct Lake semantic model from lakehouse tables
- download_workspace.py ; download a full workspace with all item definitions and lakehouse files
- run_notebook_checked.py ; run a notebook and check its exit value, exiting non-zero when the notebook's own
{ok:false}verdict fails despite aCompletedjob status (reads the exit value via the notebook job-instance beta endpoint) - deploy_notebook.py ; create or update a notebook definition fast (~1-2s) by tight-polling the LRO instead of the CLI's ~20s
Retry-Aftercadence; auto-detects create vs update,--poll-intervalis the performance lever. Strongly prefer this overfab import/nbfor any notebook definition change - task_flow.py ; create, update, export or delete a workspace task flow from a JSON spec (tasks, items as
<displayName>.<Type>, edges) through the internal metadata endpoints the Fabric UI uses; no public API orfabcommand exists for task flows
See scripts/README.md for detailed usage, arguments, and examples. Always search the scripts/ folder before writing a new helper; a script may already exist for the task.
