majiayu000 DeepWiki - Repository Documentation
Query DeepWiki for AI-generated documentation about any public GitHub repository.
Overview
DeepWiki (deepwiki.com) provides AI-generated documentation for GitHub repositories, including:
- Repository structure and architecture
- API documentation
- Code explanations
- Interactive diagrams
Quick Start
URL Pattern: Replace github.com with deepwiki.com in any repo URL:
github.com/vercel/next.js→deepwiki.com/vercel/next.js
MCP Server Setup
DeepWiki provides a free MCP server with no authentication required for public repos.
Add to Claude Code (one-time setup)
claude mcp add -s user -t http deepwiki https://mcp.deepwiki.com/mcp
For Cursor/Windsurf
Add to your MCP config:
{
"mcpServers": {
"deepwiki": {
"serverUrl": "https://mcp.deepwiki.com/sse"
}
}
}
Available MCP Tools
Once configured, these tools become available:
| Tool | Purpose |
|---|---|
read_wiki_structure |
Get documentation topics/structure for a repo |
read_wiki_contents |
Retrieve actual documentation content |
ask_question |
Ask AI-powered questions about the repo |
Usage Examples
Via WebFetch (works immediately)
# Fetch documentation overview
WebFetch https://deepwiki.com/owner/repo "Summarize the architecture"
# Example
WebFetch https://deepwiki.com/vercel/next.js "How does routing work?"
Via MCP (after setup)
Use the MCP tools directly:
mcp__deepwiki__read_wiki_structure- Get repo structuremcp__deepwiki__read_wiki_contents- Get documentationmcp__deepwiki__ask_question- Ask questions
Fallback: GitHub + AI
If DeepWiki lacks coverage for a repo, use GitHub API:
Get Repository Overview
gh api repos/owner/repo | jq '{description, language, topics, stars: .stargazers_count}'
Get README
gh api repos/owner/repo/readme --jq '.content' | base64 -d
Get File Structure
gh api repos/owner/repo/git/trees/main?recursive=1 | \
jq -r '.tree[] | select(.type == "blob") | .path' | head -50
Wire Protocols
Two protocols are supported:
- SSE at
https://mcp.deepwiki.com/sse- Official MCP spec - HTTP at
https://mcp.deepwiki.com/mcp- Cloudflare/OpenAI compatible
Best Practices
- Use WebFetch first - Works without MCP setup
- Check if repo is indexed - Popular repos have better coverage
- Ask specific questions - DeepWiki excels at targeted queries
- Fall back to GitHub - For unindexed or private repos
Limitations
- Public repos only - Private repos require Devin account
- Coverage varies - 50,000+ popular repos indexed
- No authentication - Can't access private documentation
