Deepwiki MCP Server

What is DeepWiki MCP Server?

This DeepWiki MCP server is an unofficial, community-built tool (mcp-deepwiki by regenrek) that crawled deepwiki.com pages and returned them to your editor as Markdown. Its README says it no longer works because DeepWiki blocked scraping, and recommends the official DeepWiki MCP server instead.

DeepWiki generates documentation wikis for GitHub repositories. The official DeepWiki MCP server, run by Devin, is a free remote server at https://mcp.deepwiki.com/mcp that needs no authentication for public repositories. If you searched for "deepwiki mcp" to give Cursor or Claude context about a repository, the official server is the one to install. This page covers both, clearly labeled.

How to use DeepWiki MCP Server?

Recommended: the official DeepWiki MCP server

No install, API key or account is needed for public repositories. Use the Streamable HTTP endpoint https://mcp.deepwiki.com/mcp. The SSE endpoint https://mcp.deepwiki.com/sse still exists but is being deprecated.

Claude Code

claude mcp add -s user -t http deepwiki https://mcp.deepwiki.com/mcp

Cursor

Add to .cursor/mcp.json (the same url format works in other clients that use it):

{
  "mcpServers": {
    "deepwiki": {
      "url": "https://mcp.deepwiki.com/mcp"
    }
  }
}

Claude Desktop

Add https://mcp.deepwiki.com/mcp as a remote server through Claude's custom connector settings. Devin's docs link to Anthropic's guide for connecting remote MCP servers rather than giving a config file.

For private repositories, Devin's docs point to the separate Devin MCP server, which requires a Devin account and API key.

This community server (mcp-deepwiki)

The project's original Cursor setup in .cursor/mcp.json was:

{
  "mcpServers": {
    "mcp-deepwiki": {
      "command": "npx",
      "args": ["-y", "mcp-deepwiki@latest"]
    }
  }
}

It can also be built from source with git clone https://github.com/regenrek/deepwiki-mcp.git, npm install and npm run build. Expect fetch errors: according to the README notice, DeepWiki has cut off the scraping this server relies on.

Key features of DeepWiki MCP Server

These are the community server's designed features, as listed in its README:

• Domain safety: only processes URLs from deepwiki.com
• HTML sanitization that strips headers, footers, navigation, scripts and ads
• Link rewriting so links work in Markdown
• Two output modes: one aggregated document or structured page-by-page data
• Adjustable crawl concurrency, depth, timeouts and retries via environment variables
• Progress events while crawling, and stdio or HTTP (--http) transport

The official server, by contrast, reads DeepWiki's generated wiki directly and can answer questions about a repository.

DeepWiki MCP Server tools

The community server registers one tool, deepwiki_fetch. It takes url (required; the starting deepwiki.com URL), mode (aggregate for one Markdown document, the default, or pages for structured pages) and maxDepth (default 10). It returns ok, partial or error responses with page counts and timing.

The official DeepWiki MCP server exposes three different tools:

• read_wiki_structure: lists the documentation topics for a GitHub repository
• read_wiki_contents: returns the documentation about a repository
• ask_question: answers a question about a repository with an AI-generated, context-grounded response

Use cases of DeepWiki MCP Server

With the official server, which is where these prompts work today:

• Learning an unfamiliar library: "Using DeepWiki, explain how routing works in vercel/next.js."
• Finding the right part of the docs: "List the wiki topics for shadcn-ui/ui, then read the one about theming."
• Answering a concrete question: "Ask DeepWiki how to create a new block in shadcn-ui/ui."
• Checking architecture before a contribution: "Summarize how tailwindlabs/tailwindcss structures its theme system."
• Giving a coding agent up-to-date context on a dependency without pasting docs into the chat.

DeepWiki MCP Server vs alternatives

The official DeepWiki MCP server is the direct replacement for this listing: it is maintained by DeepWiki's operator, needs no scraping and adds ask_question. For library documentation from package sources rather than DeepWiki, Context7 MCP serves version-specific docs to coding agents. To read a project's actual source, the GitHub MCP Server gives agents access to repositories, issues and pull requests.

Troubleshooting DeepWiki MCP Server

• deepwiki_fetch returns errors or empty results: this is the known failure described in the README notice. Switch to the official server at https://mcp.deepwiki.com/mcp.
• DOMAIN_NOT_ALLOWED error: the community server only accepts deepwiki.com URLs.
• Timeouts on large repositories: raise DEEPWIKI_REQUEST_TIMEOUT and DEEPWIKI_MAX_CONCURRENCY, for example DEEPWIKI_REQUEST_TIMEOUT=60000 DEEPWIKI_MAX_CONCURRENCY=10 npx mcp-deepwiki.
• EACCES permission denied: make the binary executable with chmod +x ./node_modules/.bin/mcp-deepwiki.
• Official server ignored in Devin Desktop: that client expects the serverUrl field; using the wrong field name causes the server to be silently ignored.
