Gotchas
- MCP TypeScript SDK (reference client): Answers are good but slow: about 15 s for one question. Set a generous tool timeout.
- MCP TypeScript SDK (reference client): read_wiki_contents returns the whole wiki in one response (about 1 MB for next.js). That will blow past most context windows. Use read_wiki_structure or ask_wiki_question instead.
- MCP TypeScript SDK (reference client): Unindexed repos return an error that points you to deepwiki.com to index them first.
- MCP TypeScript SDK (reference client): Validation errors are raw Pydantic output with links to errors.pydantic.dev, which is noisy for an agent to read.
