DeepWiki - AI Developer Tools Tool

Overview

DeepWiki is an AI-powered documentation generator that automatically converts public GitHub repositories into structured, wiki-style documentation with architecture diagrams, source links, and a conversational Q&A interface. The service is published by the team behind Devin and will auto-generate wikis for public repos; private-repo indexing is available via a Devin account. ([docs.devin.ai](https://docs.devin.ai/work-with-devin/deepwiki?utm_source=openai)) DeepWiki analyzes repository code, README and configuration files, builds embeddings for retrieval, and produces navigation-ready pages plus interactive Mermaid-style diagrams. It exposes programmatic access via a Model Context Protocol (MCP) server (tools include read_wiki_structure, read_wiki_contents, and ask_question) so other AI apps and assistants can query a repo’s documentation. DeepWiki is presented as free for public repos through the DeepWiki MCP endpoint; teams that need private-repo indexing can do so through Devin. Recent release notes indicate DeepWiki was launched in April–May 2025 and that a free, no-auth MCP server was added to enable integrations. ([docs.devin.ai](https://docs.devin.ai/work-with-devin/deepwiki-mcp?utm_source=openai))

Key Features

• Auto-generate wiki pages summarizing modules, core functions, and architecture.
• Interactive Mermaid diagrams visualizing module relationships and call graphs.
• Conversational Q&A (Ask) to query repository content with code citations.
• Programmatic access via MCP (read_wiki_structure, read_wiki_contents, ask_question).
• Public repos indexed for free; private-repo indexing available through Devin accounts.
• Steering via .devin/wiki.json to control wiki page generation for large repos.
• Integrations with AI toolchains and MCP-capable clients (Claude, Windsurf, Cursor).

Example Usage

Example (python):

import requests
import json

# Illustrative example: call DeepWiki's streamable HTTP MCP endpoint.
# The DeepWiki MCP offers tools like read_wiki_structure and ask_question.
# See DeepWiki MCP docs for client-specific configuration and SSE usage.
# Docs: https://docs.devin.ai/work-with-devin/deepwiki-mcp

MCP_URL = "https://mcp.deepwiki.com/mcp"

payload = {
    "tool": "read_wiki_structure",
    "params": {
        "owner": "facebook",
        "repo": "react"
    }
}

resp = requests.post(MCP_URL, json=payload, timeout=30)

if resp.ok:
    try:
        data = resp.json()
    except ValueError:
        data = resp.text
    print("Response:\n", json.dumps(data, indent=2))
else:
    print("Request failed:", resp.status_code, resp.text)

# NOTE: This is an illustrative HTTP call. Many MCP clients prefer the SSE
# endpoint (https://mcp.deepwiki.com/sse) or use an MCP-aware client library
# (Windsurf, Cursor, Claude integrations). Check the official MCP docs.

Pricing

DeepWiki-generated documentation for public GitHub repositories is available free via the DeepWiki MCP server. Private-repo indexing and deeper Devin integration require a Devin account; Devin’s published pricing shows a Core (pay-as-you-go) option (starting at $20) and a Team plan ($500/month), with Enterprise custom pricing. For private-repo access and exact billing details, see Devin’s pricing and signup pages. ([docs.devin.ai](https://docs.devin.ai/work-with-devin/deepwiki?utm_source=openai))
