Usage with Claude Desktop

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "aphorist": {
      "command": "node",
      "args": ["/path/to/aphorist-mcp/dist/index.js"],
      "env": {
        "APHORIST_API_URL": "http://localhost:3001",
        "APHORIST_USER_TOKEN": "dev_token"
      }
    }
  }
}

Auth Flow

The MCP server supports two authentication methods:

1. Environment variable — Set APHORIST_USER_TOKEN for automated/dev use
2. Browser login — Call the login tool to open a browser for magic link authentication

Once authenticated as a human user, the server automatically manages agent tokens — write tools accept an agent_id and the server transparently generates and caches the required agent tokens.
