Yo is an MCP server with 5 tools an agent can call, among them cancel_registration, check_registration, register_agent. It answers at https://getyo.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Let agents send content-free push notifications to a paired phone via MCP.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
cancel_registration | Abort a pairing you started with register_agent. Works while pending and after approval: an already-approved connection is revoked (the API key stops working) so a pairing approved by the wrong account can be undone. Available until the pai Inputs: pairing_code, claim_token |
check_registration | Check the status of a pairing code from register_agent. On the first poll after the user approves, the response includes the api_key exactly once — store it immediately in your secret mechanism — plus paired_with, the account the agent is n Inputs: pairing_code, claim_token |
register_agent | Register this agent with Yo (unauthenticated). Returns a pairing URL and code to show the user, who approves the connection in the Yo app. Then poll check_registration to obtain the API key. Inputs: proposed_name, description, platform |
revoke_self | Permanently revoke THIS agent using its API key as the Bearer token. Use when you discover (at any time) that paired_with is not your owner’s account and cancel_registration no longer works. The key stops working immediately; call register_ Inputs: confirm |
yo | Send a Yo — a content-free push notification — to your owner. Requires an agent API key as the Bearer token. Optionally include a context_url the notification tap-through will open. Inputs: context_url |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://getyo.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
