@mhdd_24/linkedin-mcp

MCP server that posts to LinkedIn through the LinkedIn API. Use it from Cursor, Claude Desktop, VS Code Copilot, or any MCP-compatible client.

You type natural language — the assistant calls create_post for you. No manual member ID setup; your LinkedIn OAuth access token resolves identity automatically.

Full documentation: docs/WIKI.md

How it works (30 seconds)

You (chat) → MCP client → linkedin-mcp → LinkedIn userinfo (access token)
                                      → LinkedIn ugcPosts API
                                      → Text post on your profile

1. Access token calls userinfo → returns memberId, name, email

2. Author URN is built from memberId — not hardcoded

3. Visibilities come from config — validated before posting

4. create_post validates visibility, POSTs the share, returns the post URN

Prerequisites

Required OAuth scopes

Obtain a token via the LinkedIn OAuth 2.0 Authorization Code flow.

Install

Option A — npm (recommended after publish)

npm install -g @mhdd_24/linkedin-mcp

This installs the linkedin-mcp CLI and compiles dist/ via the package prepack script.

Option B — npx (no global install)

npx @mhdd_24/linkedin-mcp

Downloads and runs the latest published version on each invocation.

Option C — clone and build (contributors)

git clone https://github.com/Mhdd-24/Linkedin-MCP.git
cd Linkedin-MCP
npm install
npm run build
node dist/index.js

Configure your MCP client

Cursor

Edit Cursor Settings → MCP or ~/.cursor/mcp.json:

{
  "mcpServers": {
    "linkedin": {
      "command": "npx",
      "args": ["-y", "@mhdd_24/linkedin-mcp"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "<your-oauth-access-token>",
        "DEFAULT_VISIBILITY": "PUBLIC"
      }
    }
  }
}

After global install, you can use:

"command": "linkedin-mcp"

Local development:

"command": "node",
"args": ["/path/to/linkedin-mcp/dist/index.js"]

Restart Cursor (or toggle the MCP server off/on) after saving.

Claude Desktop

%APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "linkedin": {
      "command": "npx",
      "args": ["-y", "@mhdd_24/linkedin-mcp"],
      "env": {
        "LINKEDIN_ACCESS_TOKEN": "<your-oauth-access-token>",
        "DEFAULT_VISIBILITY": "PUBLIC"
      }
    }
  }
}

Environment variables

* Or pass accessToken on each tool call.

Aliases: LI_ACCESS_TOKEN, accessToken, defaultVisibility, etc. (see WIKI).

Never commit access tokens. Put them only in MCP env or a local .env (for npm run dev).

Tools

Usage

Step 1 — Verify setup (optional)

In chat:

Run whoami on the linkedin MCP.

Expected: your LinkedIn identity and author URN.

Step 2 — See valid visibilities (optional)

list_visibilities

Examples: PUBLIC, CONNECTIONS

Step 3 — Create a post

Post to LinkedIn: Just shipped a new feature! Excited to share what we've been building.

Create a LinkedIn post with visibility PUBLIC: Happy to announce our open-source MCP server for LinkedIn integration.

create_post parameters

* Optional when DEFAULT_VISIBILITY is set in MCP config.

What happens after npm install?

1. Package files land in node_modules/@mhdd_24/linkedin-mcp/ (or global prefix if -g).

2. prepack / publish includes compiled dist/ — no local build needed for end users.

3. The linkedin-mcp bin points to dist/index.js.

4. Your MCP client runs that entry over stdio (stdin/stdout = MCP protocol; logs go to stderr).

5. On startup: validateEnv() warns if access token is missing.

6. Tools are registered; the server waits for CallTool requests from the AI.

After publishing to npm (maintainers)

1. Bump version in package.json and src/config/linkedin.config.ts (LI.SERVER.VERSION).

2. Build and test: npm run build then test with local mcp.json.

3. Publish: npm publish --access public (logged in as package owner).

4. Users update by restarting MCP — npx picks up the new version automatically.

5. Global install users: npm update -g @mhdd_24/linkedin-mcp.

Current package version: 1.0.0.
