• Whether its tools do the product's job has not been judged yet.
• Checked on 1 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

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 (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). 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 →

• sw_get

  Gets one Star Wars entity by numeric record id and returns it as a JSON object. Take the id from the end of an entity's url field (from sw_search, sw_list or a relation URL). Ids are record ids, not episode numbers: FILMS id 1 is A New…

• sw_list

  Lists every entity of one Star Wars resource type as a JSON array (Episodes I-VI data). Responses are large (all 82 PEOPLE, about 38 KB); to find a single entity, prefer sw_search, then sw_get; for a compact index pass fields, e.g…

• sw_random

  Returns one random Star Wars entity of the given resource type as a JSON object. Each call can return a different entity, so it is not idempotent. Useful for demos and quizzes; to fetch a specific entity use sw_search or sw_get.

• sw_search

  Start here. Finds Star Wars entities by name (title for FILMS) with a case-insensitive substring match: 'sky' finds Luke, Anakin and Shmi Skywalker. Returns a JSON array of full entities; an empty array [] means no match; pass fields to…
