Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

MCP server for the Guerrilla Mail temporary/disposable email API. Spin up throwaway inboxes, poll for mail, and read messages from any MCP client — Claude Desktop, Claude Code, Cursor, or any other.
Zero config. No API key. One command.
npx -y guerrillamail-mcpWhy
Need a throwaway email inside an AI workflow — signup testing, OTP capture, scratch inbox — without leaving the agent? This wires Guerrilla Mail's disposable inboxes straight into the Model Context Protocol so your agent can create an address, watch for mail, and read it, all on its own.
