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
