What an inspection observes

Four layers of evidence, captured passively on every observation.

Protocol & transport era

Streamable HTTP, SSE, or the modern stateless era — plus the negotiated protocol version, straight from the initialize handshake.

Capability inventory & schemas

Every advertised tool, resource, and prompt, with full input schemas: parameters, types, constraints, and which ones are required.

Contract hash & drift

A canonical hash of the normalized surface. When it changes, you get a structured diff, classified from breaking to informational.

Availability & latency

Reachability, response time, and auth behavior on every check — accumulated into an uptime history that starts honest and stays honest.

Inspect freely. Let us do the watching.

The whole public record — inventories, timelines, contract diffs — is free for everyone, always. Add an account and MCP Tools watches your endpoints continuously and tells you the moment something meaningful changes. Free Pro until 12/31/2026 — no credit card.
