Model Context Protocol

MCP server directory

25 public MCP servers, each checked by Merlonix with a real Model Context Protocol handshake — not just a ping. See the transport, protocol version, authentication posture, callable tool inventory, and an A–F security-posture grade for each.

Last checked at Jul 7, 2026, 09:39 PM UTC. These are point-in-time observations, not real-time — re-check any server live.

Independent directory maintained by Merlonix. Not affiliated with, endorsed by, or operated by the listed vendors. Each health check is Merlonix’s own point-in-time observation of a public endpoint; vendor names are used nominatively to describe what we checked. 6 of these servers expose their tools without authentication; the rest are live but gated behind a credential.

Check any MCP server — free, no signup.

Paste any MCP endpoint and Merlonix opens a real handshake: protocol version, tool inventory, transport, and an A–F security-posture scan. Then monitor it around the clock and catch silent tool-contract drift before it breaks your agents.
