Socials MCP

Give Claude superpowers on X, LinkedIn, and Reddit.

Install

1. Load the Socials browser extension in your browser (companion app, distributed separately)

2. Build and run this MCP server from source (see Development below)

3. Register the server with Claude Code by pointing your MCP config at dist/index.cjs

Then talk to Claude naturally:

• "Connect with 100 LinkedIn recruiters hiring for React roles"

• "Find Reddit threads about note-taking and mention my app naturally"

• "Reply to 50 X posts about indie hacking and promote my SaaS"

How it works

The MCP server runs locally and bridges Claude to your browser via a WebSocket connection to the Socials extension. All actions happen through your real browser session — no API keys, no rate limits.

Troubleshooting

• Port 9847 in use — Kill stale node processes or set SOCIALS_MCP_RECLAIM_PORT=1

• Extension not connecting — Open the Socials side panel, then reload

• Tools not working — Make sure you're signed into Socials

Development

npm install
npm run build       # build dist/
npm run typecheck   # type check

Use local MCP in plugin dev mode

1. Build local MCP:

npm run build

1. Point your MCP client config at the local build:

{
  "mcpServers": {
    "socials": {
      "env": {
        "SOCIALS_MCP_DEV_MODE": "1",
        "SOCIALS_MCP_DEV_MCP_PATH": "/absolute/path/to/dist/index.cjs"
      }
    }
  }
}

1. Restart Claude Code.

To switch back to the default bundled server, set "SOCIALS_MCP_DEV_MODE": "0" and restart.
