DeepWiki MCP for Claude Code & Grok — chat with any public GitHub repo's auto-generated documentation, wiki pages, and Q&A without cloning.
/plugin marketplace add 88plug/claude-code-plugins
/plugin install deepwiki@88plug
grok plugin marketplace add 88plug/claude-code-plugins
grok plugin install deepwiki@88plug --trust
No API key, no local MCP server, no config file. The plugin registers Cognition AI's remote DeepWiki MCP endpoint; Claude Code and Grok connect over HTTP.
After install, ask your AI agent about any public GitHub repository:
Using deepwiki, how does the React reconciler schedule work?
The agent calls the DeepWiki MCP tools, reads the indexed documentation for facebook/react, and answers in the same turn — no clone, no local wiki build.
Other prompts that work well:
Using deepwiki, summarize the architecture of vercel/next.js
Using deepwiki, what does read_wiki_structure return for torvalds/linux?
Mention deepwiki (or the owner/repo) so the agent routes to the MCP server instead of guessing from training data.
DeepWiki is a thin Claude Code plugin that wires up Cognition AI's hosted DeepWiki MCP server (Model Context Protocol). It gives Claude and other AI agents read-only access to auto-generated GitHub documentation and natural-language Q&A over public repositories.
Use it when you want to:
- Research an unfamiliar codebase before adopting or contributing
- Answer dependency questions without leaving your Claude Code session
- Pull architecture and API context into a task without cloning gigabytes of source
- Give LLM agents a wiki-style documentation surface instead of raw tree walks
Any public repo at github.com/<owner>/<repo> is reachable. Cognition's DeepWiki indexes it and serves the docs; this plugin is the one-command install path so your agent can query it programmatically.
| Feature | Detail |
|---|---|
| Marketplace install | One command via the 88plug Claude Code plugins marketplace |
| No API key | No local process, no manual MCP config |
| Remote MCP server | HTTP to https://mcp.deepwiki.com/mcp |
| Read-only research | Agent reads docs and asks questions — nothing more |
| Any public GitHub repo | Works against github.com/<owner>/<repo> |
| Agent-friendly | Surfaces as named MCP tools your LLM can call |
The plugin exposes one MCP connection named deepwiki (model-context-protocol tools):
| Tool | What it does |
|---|---|
read_wiki_structure | List auto-generated documentation / wiki pages for a repository |
read_wiki_contents | Fetch the full documentation for a repository |
ask_question | Ask a natural-language question about a repository; get an AI-generated answer |
You normally do not call these by hand. Mention deepwiki or a GitHub repository in your prompt and the agent selects the right tool. That workflow fits AI agents, automation, and developer-tools CLI use inside Claude Code.
- Developers who use Claude Code (Anthropic) and need fast documentation lookup on public GitHub projects
- AI agent builders who want a documentation / wiki MCP server without hosting one
- Teams doing LLM-assisted research, onboarding, or dependency review against open-source codebases
- Anyone who wants RAG-style answers over repo docs without standing up a local index
Note
This plugin is configuration only. Indexing, the model, and the served documentation are operated by Cognition AI (the team behind Devin) at https://mcp.deepwiki.com/mcp. 88plug does not run the underlying service. When the agent queries DeepWiki, your query text goes to that endpoint; the plugin does not proxy or log anything. Only public repositories are indexed — do not send private repository names.
What this plugin is, and what it isn't
- Is: a small plugin manifest that registers the remote MCP endpoint and surfaces it through the 88plug marketplace as a single install command. No original business logic.
- Is not: the DeepWiki service itself. If the upstream endpoint changes or goes down, this plugin is just config — open the manifest and update the URL.
Local checkout is only needed if you are changing the plugin packaging:
git clone https://github.com/88plug/deepwiki.git
cd deepwiki
claude --plugin-dir "$PWD"The live MCP URL is pinned in .claude-plugin/plugin.json (type: http, https://mcp.deepwiki.com/mcp). See tests/smoke.sh for the smoke checks that guard that URL and the marketplace entry shape.

Issues and pull requests are welcome at 88plug/deepwiki. Keep changes small; the plugin is intentionally a thin wrapper over the remote MCP server.
