Agent Embassy is an MCP server with 33 tools an agent can call, among them agentid_issue, agentid_renew, agentid_revoke. It answers at https://agent-embassy.fly.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 4 of 4 times since 23 September 2026; the last check, on 7 November 2026, succeeded.
Agents pay for work and prove it. Verified checks $0.15, recovery $1.00. USDC on Base via x402.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://agent-embassy.fly.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.
