Claude integration · MCP

Run PosterAI from Claude

PosterAI ships an MCP server, so you can draft, schedule and manage posts across Instagram, TikTok and LinkedIn just by chatting with Claude — no dashboard required.

Setup

Requires Node.js 18+. There's nothing to install manually — npx fetches the posterai-mcp package automatically.

How to install Node.js

Check what you have: node --version (should be 18 or higher). If it's missing or older, install it via:

  • Download the LTS installer from nodejs.org (works on macOS, Windows and Linux).
  • macOS (Homebrew): brew install node
  • Windows (winget): winget install OpenJS.NodeJS.LTS
  • Linux / version manager: nvm nvm install 20
  1. 1

    Create an API key in PosterAI → Settings.

  2. 2

    Add it to your Claude client

    Claude Code — run in your terminal:

    claude mcp add posterai --env POSTERAI_API_KEY=pk_your_api_key -- npx -y posterai-mcp

    Claude Desktop — add this to your config file, then save:

    {
      "mcpServers": {
        "posterai": {
          "command": "npx",
          "args": ["-y", "posterai-mcp"],
          "env": { "POSTERAI_API_KEY": "pk_your_api_key" }
        }
      }
    }
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
  3. 3

    Replace pk_your_api_key with your key and restart Claude. The PosterAI tools will be available.
