DeepWiki MCP Tools

When to Use

• Understanding a GitHub repository's architecture
• Cross-repo comparisons and Q&A
• Finding how a specific feature is implemented in a repo
• Getting an overview of unfamiliar codebases

Available Tools

• mcp__deepwiki__read_wiki_structure — Get documentation topics for a repo
• mcp__deepwiki__read_wiki_contents — Read full documentation for a repo
• mcp__deepwiki__ask_question — Ask any question about a repo

Query Strategies

• Start with read_wiki_structure to understand what documentation is available
• Use ask_question for specific implementation questions: "How does auth work in owner/repo?"
• For comparisons, ask about each repo separately then synthesize
• Repository names use owner/repo format (e.g., "langchain-ai/langchainjs")

Limitations

• Free to use, no API key required
• Only works with public GitHub repositories
• Documentation is AI-generated and may miss recent changes
• Best for architecture-level understanding, not line-by-line code review
