AI tools (MCP)

Connect an AI assistant such as Claude Code, Codex, Cursor, or VS Code to Harmony, then ask about your contacts, calls, transcripts, and workflows in plain language. The assistant can read your data but can't change it.

What you need​

  • A Harmony API key. Create one in Settings > Developers.
  • The Harmony MCP server address:
    • US: https://api.harmony.ai/api/mcp
    • EU: https://api.eu.harmony.ai/api/mcp, if you sign in at app.eu.harmony.ai

Set up your assistant​

For other assistants, see Tools and details.

OAuth support is in progress​

ChatGPT, and Claude without the request headers beta, connect only through OAuth sign-in. Harmony is adding OAuth support, so these assistants can't connect yet.

Things to ask​

  • "List my Harmony workflows."
  • "Find the contact Dana Lee in Harmony and list their calls."
  • "Summarize the transcript of their last call."

Keep your key safe​

Your assistant can read everything you can read in Harmony, and it sends what it reads to its AI model. Use a separate key for each assistant, never commit a key to a repository, and revoke keys you no longer use.
