DeepWiki MCP Skill

Ask questions and read documentation about any GitHub repository using DeepWiki MCP. Use when you need to understand a codebase, find specific APIs, or get context about a repository.

DeepWiki Skill

Use this skill to query GitHub repository documentation and ask questions about codebases.

Prerequisites

• uxc is installed and available in PATH.
• Network access to mcp.deepwiki.com/mcp

Note: Repositories must be indexed on DeepWiki first. Visit https://deepwiki.com to index a repository.

Install uxc

Choose one of the following methods:

Homebrew (macOS/Linux):

brew tap holon-run/homebrew-tap
brew install uxc

Install Script (macOS/Linux, review before running):

curl -fsSL https://raw.githubusercontent.com/holon-run/uxc/main/scripts/install.sh -o install-uxc.sh
less install-uxc.sh
bash install-uxc.sh

Cargo:

cargo install uxc

Core Workflow

1. Use fixed link command by default:

   • command -v deepwiki-mcp-cli
   • If missing, create it: uxc link deepwiki-mcp-cli mcp.deepwiki.com/mcp
   • deepwiki-mcp-cli -h
   • If command conflict is detected and cannot be safely reused, stop and ask skill maintainers to pick a different fixed command name.

2. Ask a question about a repository:

   • deepwiki-mcp-cli ask_question repoName=owner/repo question='your question'

3. Read wiki structure:

   • deepwiki-mcp-cli read_wiki_structure repoName=owner/repo

4. Read wiki contents:

   • deepwiki-mcp-cli read_wiki_contents repoName=owner/repo

Available Tools

• ask_question: Ask any question about a GitHub repository and get an AI-powered response
• read_wiki_structure: Get a list of documentation topics for a repository
• read_wiki_contents: View documentation about a repository

Usage Examples

Ask about a codebase

deepwiki-mcp-cli ask_question repoName=facebook/react question='How does useState work?'

Explore repository structure

deepwiki-mcp-cli read_wiki_structure '{"repoName":"facebook/react"}'

Read documentation

deepwiki-mcp-cli read_wiki_contents repoName=facebook/react

Output Parsing

The response is an MCP JSON envelope. Extract the content from .data.content[].text.

Notes

• Maximum 10 repositories per question
• Some popular repositories may already be indexed
• Responses are grounded in the actual codebase
• deepwiki-mcp-cli <operation> ... is equivalent to uxc mcp.deepwiki.com/mcp <operation> ....
• If link setup is temporarily unavailable, use direct uxc mcp.deepwiki.com/mcp ... calls as fallback.
