Gotchas
- MCP TypeScript SDK (reference client): resources/list returns MCP error -32601 (Method not found). The server offers tools and prompts only.
- MCP TypeScript SDK (reference client): There is no fetch-page tool. You can only search, so you cannot pull a specific docs URL by path.
- MCP TypeScript SDK (reference client): Search is slow (about 3 to 4 s) and returns large blocks of XML-style results (about 28 KB), which eats context. The top hit for "Workers KV" was the Glossary page, not the KV docs.
- MCP TypeScript SDK (reference client): A no-match search returns an empty text block with no "no results" message, so clients must handle an empty response.
