out of 100, Discoverable

How far an agent gets, and where it stops. Routes run in parallel: no document is required to reach a server, and no server is required to publish one.

Starting from the bare domain

  • observed

    Server card D1

    GET each published candidate path

  • not observed

    DNS record D2

    TXT lookup at _mcp.<domain>

    Nothing at the paths this profile publishes. Not proof of absence.

  • not observed

    Conventional endpoint D3

    HEAD the conventional endpoint locations

    Nothing at the paths this profile publishes. Not proof of absence.

  • not observed

    Authorization metadata D4

    GET /.well-known/oauth-protected-resource

    No authorization metadata. Authorization is optional in MCP, so this says nothing about conformance.

  • not observed

    Advertised by the home page D7

    GET /, then read the Link header and the head

    Nothing at the paths this profile publishes. Not proof of absence.

Nothing converged on a server

  • not observed

    A server answered D5

    One unauthenticated JSON-RPC call to the endpoint

    Nothing at the paths this profile publishes. Not proof of absence.

  • not reached

    It listed its tools D6

    tools/list on the same connection

    The evidence this needs was never collected.

Holding the two ends against each other

  • not reached

    The card matches the server C1

    Compare the card's claims against the handshake

    The evidence this needs was never collected.

Not measured here

  • outside this profile

    Link relations on any page other than the home page

  • outside this profile

    Fetching an advertised catalog to see what is in it

  • outside this profile

    Anything behind authentication, or in a marketplace

A skip is not a failure: it means the check could not run, usually because an earlier one found nothing to work with. What each check does, and on what authority.
