Wikidata as tools for your agent. Unofficial: not affiliated with or endorsed by wikidata.org. Unbrowse compiled these from wikidata.org's own requests: each call replays the site's first-party API server-side and returns a verified result. No scraping of rendered pages, no browser on your side, no wikidata.org API key.
Connect the wikidata.org MCP
This server is a tool scope holding only wikidata.org: its compiled tools plus the Unbrowse tools that run them, so the agent's tool list stays small and every call stays on wikidata.org.
claude mcp add --transport http wikidata https://unbrowse.ai/mcp/wikidata.org

{"mcpServers":{"wikidata":{"url":"https://unbrowse.ai/mcp/wikidata.org"}}}
The first connect signs in to Unbrowse with OAuth (free tier, only verified results count). For scripts, send Authorization: Bearer $UNBROWSE_API_KEY (key from https://unbrowse.ai/app/keys; keep it in a secret manager, never in config you commit).
If none of the tools below are in this session's tool list, the server is not connected or not signed in: say so and stop. Do not fetch wikidata.org some other way and present it as this skill's result.
Tools
wikidata_org__get_w_3 — Search wikidata
Search wikidata. Inputs: query. Returns the page's title, readable text and links. Read-only on wikidata.org.
query(string, required) — query (typed during “fill Search Wikidata”)title(string) — optional, e.g. "Special:Search"ns0(integer) — optional, e.g. "1"select(array) — Keep only these parts of the result: dots walk keys, [] maps over a list, a final {a,b} keeps several keys (e.g. "results[].{title,url}"). Unmatched paths come back in selectMissing.- 1 more of the site's own parameters (locale, paging and the like), sent as recorded
{"query":"<query>"}
Always there too: unbrowse.run (a task on wikidata.org in plain words), unbrowse.inspect, unbrowse.resume, unbrowse.scrape and unbrowse.map (any page on wikidata.org), and the recorded cloud browser unbrowse.browse.open → unbrowse.browse.act → unbrowse.browse.finish. Hosts that reject dotted names show them with _ (unbrowse_run).
How to call
- Pick the tool whose title matches the job and pass its inputs. Leave the site's recorded parameters out unless the user asked for something they control.
- Read
status.succeededcarries the verifiedresult.input_requiredis not a failure: answer the open fields withunbrowse.resume {runId, answers}on the same run. - No tool fits:
unbrowse.run {task}. It fails withno_capabilitywhen nothing is compiled for that yet: do it once withunbrowse.browse.openon wikidata.org →unbrowse.browse.act→unbrowse.browse.finish, which compiles a new tool this server lists next time. Anything off wikidata.org is refused here (not_in_scope): use the general Unbrowse server for that. - Signing in: never ask the user for a password.
unbrowse.browse.actwithaction: "autofill"fills wikidata.org's login from their Unbrowse password manager. - Report only what a
succeededresult says.outcome_unknownmeans a change may have happened: check before retrying. Posting, buying, sending or deleting needs the user's go-ahead.
Without MCP
Every tool is also a REST call:

-H "authorization: Bearer $UNBROWSE_API_KEY" -H "content-type: application/json" \
-d '{"query":"<query>"}'
OpenAPI: https://unbrowse.ai/api/v1/sites/wikidata.org/openapi.json. Every other site: the general Unbrowse skill (https://github.com/unbrowse-ai/unbrowse) and https://unbrowse.ai/mcp.
