• 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 →

• get_pricing

  Formation packages, the trademark package, and USPTO fees.

• quote_application

  Every fee for a number of classes, with the government's marked. Saves nothing.

  Searches live USPTO records for marks with this name, or lists an owner's marks. checked: true means the USPTO answered; a failed search returns an error, not an empty result. Federal records only.

• suggest_alternatives

  Names that keep the idea of a risky mark. Each has passed the refusal screen and a USPTO search.

  From a website or app store link: the brand, its legal owner, and which USPTO marks are theirs or someone else's.
