For the publisher
- This server is in the heaviest 10 % of the registry. 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.317.custom.input_schema: JSON schema is invalid. It must match JSON Schema draft 2020-12 (https://json-schema.org/draft/2020-12). Learn more about tool use at https://platform.claude.com/docs/en/agents-and-tools/tool-use/overview.). A client that validates schemas can refuse them too.
