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 structure mcp__deepwiki__read_wiki_contents - Get documentation mcp__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 Resources Website: https://deepwiki.com Docs: https://docs.devin.ai/work-with-devin/deepwiki GitHub: https://github.com/CognitionAI/deepwiki
