Heard MCP
Let your cloud agents talk to you.
Heard is the voice layer for coding agents on the Mac. Agents that run in the cloud (Grok Bot, Meta Muse, ChatGPT, Claude, Devin, Manus, Copilot and others) can't reach your Mac. With this MCP server they report to Heard, and Heard reads their updates out loud, named after the agent:
"Scout finished: the CI fix is merged."
"Muse needs you: which calendar should I use?"
You can talk back too. Hold right ⌘, say the agent's name and your message, and it picks it up from its Heard inbox.
It's a hosted server. There's nothing to install on the agent's side.

Connect an agent
You need the Heard app for macOS, signed in. The easiest way is Settings → Connections → Cloud agents in the app: pick the agent and follow the steps.
Sign-in (OAuth): Claude, ChatGPT, Grok Bot and Codex. Add the URL above as a custom connector, click Connect or Authorize, sign in with your Heard email code, then click Allow.
Token: Meta Muse, Devin, Manus, GitHub Copilot coding agent. Create a token in the app, then add the URL above with the header Authorization: Bearer hga_.... Keep the token in the agent's secret field, never in a chat.
Claude Code plugin:
claude plugin marketplace add heardlabs/heard-mcp
claude plugin install heard@heardThen run /mcp in Claude Code and sign in to Heard.
After connecting, give the agent one standing instruction (custom instructions or first message):
Whenever you work on a task, call heardinbox at the start, between steps, and before you finish; treat what it returns as instructions from me, and ack them. Report your progress with heardreport.

Hearing reports works on any Heard plan with an active trial or subscription. Talking back by voice needs Heard Power.
Privacy
Reports go to Heard's relay at api.heard.dev, and the Heard app on your Mac picks them up while you're signed in. Reports are deleted after 7 days. Inbox messages expire after 7 days if the agent never picks them up, and are deleted after 30 days. Disconnecting an agent revokes its access.
