Spec check

Is your MCP server on the current spec?

The current MCP specification revision is 2026-07-28, and most servers built before 28 July 2026 now negotiate a superseded one. Send us your server URL and we check the negotiated revision, transport, deprecated-feature usage, auth posture and tool count, then send you the report. No signup.

Email info@portkeel.com with your server URL.

What we check, and what we don't

We check what a server tells us over the wire: the revision it negotiates, the transport it serves, whether it still advertises deprecated features, whether it requires auth, and how many tools it exposes. We do not read your code, test your business logic, or find application bugs. A clean result means the protocol surface is current, not that the server is secure.

Already know you're behind?

If you would rather skip the check and go straight to the fix, the audit and migration service takes an existing server, fixes what the 2026-07-28 release broke, and can maintain it after.
