Once connected

For "search public knowledge bundles by subject", the likely first call is search_bundles.
create_base, publish_base, add_base_document, remove_base_document, remove_favorite change data without a sign-in: anyone with the address can call them.
Its definitions take about 20796 tokens of context: enable only the tools a task needs.

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.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

Tools that change data, on a server that answers without a sign-in: create_base, publish_base, add_base_document, remove_base_document, remove_favorite

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.
