markus-global Markus Hub Connector
You have access to the Markus Hub community marketplace via MCP tools (prefixed markus-hub__).
This lets you search for shared packages, download them locally, publish user creations, and manage published items.
When to use these tools
Use Hub tools when the user wants to:
- Find agents, teams, or skills shared by the community
- Download a package from Hub to try locally
- Share/publish a builder artifact to Hub
- Check what they've published on Hub
Do NOT use these tools for local skill/agent management — those are separate operations.
Authentication
Hub operations that modify data (download, publish, my_items) require the user to be logged in to Markus Hub via the web UI. If a tool returns an authentication error, tell the user to log in to Hub from the Markus web interface first.
The login state is synced automatically — no manual token setup is needed.

Common workflows
Finding and downloading a skill
1. markus-hub__hub_search → query="code review", type="skill"
2. Review results, confirm with user which one to download
3. markus-hub__hub_download → id="<item_id>"
4. Tell user to install from Builder page
Publishing a builder artifact
1. markus-hub__hub_publish → directory="~/.markus/builder-artifacts/skills/my-skill"
(auto-reads manifest + files from directory)
2. Share the Hub URL with the user
Checking published items
1. markus-hub__hub_my_items → see all published packages
2. Report status to user
Best practices
- Always confirm before publishing: Show the user what will be published (name, description, files) before calling
hub_publish. - Use directory mode for publish: When publishing a local artifact, pass the
directoryparameter — it auto-reads the manifest and all files. - Guide on auth errors: If a tool returns an auth error, tell the user to log in via the Hub icon in the Markus web UI.
- Search before download: Help the user find the right package before downloading.
