Whose server it is
  • Registry namecom.voice-school/lesson-bookingverified in the MCP registry

The registry name sits under voice-school.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_lesson_request, create_social_post_draft, publish_social_post

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
