Linkedin MCP Server

MCP server for interacting with Linkedin Community Management API.

This MCP server:

• Can be hosted locally or remotely : uses HTTP+SSE transport defined in MCP

• Implements the Draft Third-Party Authorization Flow from MCP specs to delegate authorization to LinkedIn's OAuth authorization server

⚠️ Disclaimer: The Third-Party Authorization Flow proposal status is currently in draft. The only MCP client, to my knowledge, that currently implements this specification of the protocol is the MCP Inspector

Features

Tools

• user-info - Get current logged in user infos (name, headline and profile picture)

• create-post - Create a new post on LinkedIn
