LinkedIn Post MCP

An MCP (Model Context Protocol) server that lets an MCP client (e.g. Claude) publish posts to a LinkedIn profile via the official LinkedIn API.

How it works

  • 3-legged OAuth (member token) against LinkedIn (openid profile w_member_social) — the member authorizes once, the resulting access/refresh token is persisted locally and refreshed automatically.

  • FastMCP server, HTTP transport on /sse. Authentication towards the MCP client is expected to be handled upstream (e.g. by an MCP gateway); here OAuth is only towards LinkedIn.

  • Tools: import an existing token, run the interactive OAuth flow, post a text post (supports markdown formatting → LinkedIn richtext), inspect token state.
