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 (invalid x-api-key). A client that validates schemas can refuse them too.
