Marketplace Publish Extension

Publish (register or update) a dcc-mcp extension package to a marketplace catalog (marketplace.json).

Tools

marketplace_publish_extension__publish

Scan an extension directory, build a CatalogEntry, and upsert it into the target marketplace.json (local file or remote URL-backed file). When the catalog source is a local git repository the tool can optionally commit and push the change.

Prerequisites

• dcc-mcp-core installed
• Write access to the target marketplace catalog path
• Git (if using commit+push mode)

Workflow

1. Point the tool at a local extension directory containing SKILL.md.
2. The tool reads the SKILL.md frontmatter and any accompanying metadata.
3. Additional CLI-supplied fields (install url, ref, tags, maintainer, icon, etc.) are merged in.
4. A CatalogEntry is built and upserted into the target marketplace.json.
5. If the catalog source is a git repo and --commit is passed, the updated marketplace.json is committed and pushed.
