Claude Code plugin: use deepwiki-open as RAG context provider via MCP

[MuLeiSY2021]

Hi! I built a Claude Code plugin that integrates deepwiki-open as a knowledge backend: deepwiki-mcp

What it does

It exposes deepwiki-open's wiki pages and code index as MCP (Model Context Protocol) tools, so Claude Code can automatically pull repository knowledge during coding sessions.

4 tools available

Tool	What it does
list_projects	List all indexed repositories
get_wiki_structure	Browse wiki table of contents
get_wiki_page	Read AI-generated documentation pages
search_repo	Semantic search over source code via FAISS (requires PR #496)

Bundled agent

The plugin includes a deepwiki agent that auto-resolves repository URLs — users just say "tell me about this project" and it figures out the repo from git remote or GitHub search. No need to paste full URLs.

Demo

# User is in a git repo, asks about architecture
> Ask deepwiki about the architecture of this project

# Agent auto-resolves URL, fetches wiki structure, reads relevant pages
# Claude Code synthesizes the answer using wiki content as context

For source-code-level questions, search_repo performs true vector similarity search over the indexed codebase and returns relevant code chunks — Claude Code then reasons over them directly.

Install

# In Claude Code
/plugin marketplace add MuLeiSY2021/deepwiki-mcp
/plugin install deepwiki-mcp

Requires deepwiki-open running locally (default http://localhost:8001).
