DeepWiki¶

DeepWiki MCP for Claude Code & Grok — chat with any public GitHub repo's auto-generated documentation, wiki pages, and Q&A without cloning.

Install¶

Claude Code¶

/plugin marketplace add 88plug/claude-code-plugins
/plugin install deepwiki@88plug

Grok Build¶

grok plugin marketplace add 88plug/claude-code-plugins
grok plugin install deepwiki@88plug --trust

Tip

That is the whole setup. No API key, no local server, no MCP config file. The plugin registers Cognition AI's remote MCP endpoint; Claude Code and Grok connect over HTTP.

Quickstart¶

After installing, ask about any public repository:

Using deepwiki, how does the React reconciler schedule work?

The agent calls the DeepWiki tools, reads the indexed documentation for facebook/react, and answers in the same turn — without cloning the repo.

What it does¶

DeepWiki is a thin Claude Code plugin that wires up Cognition AI's hosted DeepWiki MCP server. It gives your agent read-only access to auto-generated documentation and Q&A over public GitHub repositories.

Use it when you want to:

Understand an unfamiliar codebase before adopting or contributing to it
Answer questions about a dependency without leaving your session
Pull architecture and API context into a task without cloning gigabytes of source

Any public repo at github.com/<owner>/<repo> is reachable. DeepWiki indexes it and serves the documentation; this plugin lets the agent query it programmatically.

Features¶

Feature	Detail
Marketplace install	One command via the 88plug marketplace
No API key	No local process, no manual MCP config
Remote MCP	Connects to `https://mcp.deepwiki.com/mcp` over HTTP
Read-only	The agent reads docs and asks questions — nothing more
Any public GitHub repo	Works against `github.com/<owner>/<repo>`

MCP tools¶

The plugin exposes one MCP connection named deepwiki:

Tool	What it does
`read_wiki_structure`	List the auto-generated documentation pages for a repository
`read_wiki_contents`	Fetch the full documentation for a repository
`ask_question`	Ask a natural-language question about a repository and get an AI-generated answer

You normally do not call these by hand. Mention deepwiki or a repository in your prompt and the agent selects the right tool.

Remote service¶

Note

This plugin is configuration only. The 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 is sent to that endpoint; the plugin does not proxy or log anything. Only public repositories are indexed, so do not send private repository names.

Tip

If the upstream endpoint changes or goes down, open .claude-plugin/plugin.json and update the MCP URL. This plugin is just config — no original business logic.

Contributing¶

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

Development¶

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.
