Composio MCP — Auth Setup

Composio uses an API key to authenticate requests and manage your connected integrations.

1. Get your credentials

  1. Open the Composio Settings page (opens Composio — we never see your key)
  2. Navigate to API Keys and copy your existing key or generate a new one

2. Set environment variables

macOS / Linux — add to ~/.zshrc or ~/.bashrc:

export COMPOSIO_API_KEY=YOUR_API_KEY_HERE

Then run source ~/.zshrc (or open a new terminal).

Windows — run in Command Prompt (then restart):

setx COMPOSIO_API_KEY "YOUR_API_KEY_HERE"

3. Verify

npx claude-skills doctor

You should see ✅ next to the Composio MCP entry. If you see ❌, confirm the key is set: echo $COMPOSIO_API_KEY.

4. Restart Claude Code

Quit and reopen Claude Code (or run /mcp list inside Claude Code to confirm the Composio MCP appears).
