Inspect a public service

InterfaceDelta discovers the machine-readable surfaces a service publishes for agents (ARD, A2A, MCP, declared OpenAPI and WebMCP forms), or inspects a known endpoint directly, and normalizes the result into a Passport. It works for any public service, whether or not a registry lists it. Observation is bounded and passive: no tool is called and nothing is authenticated.

Paste a service URL, an MCP endpoint or an OpenAPI document URL. A bare domain such as example.com is inspected over HTTPS.

Type and separate MCP endpoint

Optional: add a separate MCP endpoint only when it is different from the URL above. Cross-origin endpoints require this explicit input.

One-time inspection. Not recorded to an account and not followed. Sign in to keep future inspections.

Live controlled service · synthetic data · real network inspection starts only when you choose Inspect.
