Cloudflare Docs: task by task
- Works connect (no auth) (295 ms)
- Works list tools (126 ms)
- Works search ("Workers KV") (4.0 s)
- Works read (migrate_pages_to_workers_guide) (173 ms)
- Works search with no matches (3.0 s)
- Works error handling (malformed args) (28 ms)
Cloudflare Docs gotchas
- resources/list returns MCP error -32601 (Method not found). The server offers tools and prompts only.
- There is no fetch-page tool. You can only search, so you cannot pull a specific docs URL by path.
- 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.
- A no-match search returns an empty text block with no "no results" message, so clients must handle an empty response.
