On 2026-10-20 the server answered initialize and tools/list without a sign-in. First answer in 624 ms.

• Its tools do none of the product's use cases we checked: add beat and section markers to Premiere Pro timelines; check tide times and heights on a Garmin watch; redact tracked objects from CCTV footage offline.

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.

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 →
