For the publisher
- This server is in the heaviest 10 % of the registry. Its 5 most expensive tools are 61 % of the cost. Shorter descriptions, fewer optional parameters and fewer tools cut the cost. The command npx mcpcost --url <endpoint> --tools 50 lists every tool with its cost.
- The Anthropic count_tokens endpoint refused the tool schemas (tools.1.custom.input_schema: input_schema does not support oneOf, allOf, or anyOf at the top level). A client that validates schemas can refuse them too.
