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

Installation

Follow those instructions to run Linkedin MCP server on your host. You'll need to provide your own Linkedin client.

Requirements

- Node 22 (lts/jod)
- pnpm 10
- a Linkedin client with Community Management API product installed and http://localhost:3001/callback added to the authorized redirect URLs

Instructions

- Install dependencies:

pnpm install

- Create env file and populate with your Linkedin client credentials and a random string secret value for JWT_SECRET:

cp .env.template .env && vi .env

- Run the server:

pnpm run dev

- Configure your favorite MCP client to use this new server:

{
  "mcpServers": {
    "linkedin": {
      "url": "http://localhost:3001/sse"
    }
  }
}

Debugging

Start the MCP Inspector to debug this server, which is available as a package script:

pnpm run inspector

Access the inspector in your browser at http://localhost:5173
