Context7 Documentation

MCP service at https://mcp.context7.com/mcp (http) with 2 tools.

Requirements

• mh CLI must be installed. If not available, install with:

  curl -fsSL https://raw.githubusercontent.com/vaayne/mcphub/main/scripts/install.sh | sh
  

Usage

List tools: `mh list -u https://mcp.context7.com/mcp -t http`
Get tool details: `mh inspect -u https://mcp.context7.com/mcp -t http <tool-name>`
Invoke tool: `mh invoke -u https://mcp.context7.com/mcp -t http <tool-name> '{"param": "value"}'`

Notes

• Run inspect before invoking unfamiliar tools to get full parameter schema
• Timeout: 30s default, use --timeout <seconds> to adjust
• Important: Always call resolveLibraryId first to get the Context7-compatible library ID before calling queryDocs, unless user provides ID in /org/project format
• Do not call either tool more than 3 times per question

Tools

Tool	Description
resolveLibraryId	Resolves a package/product name to a Context7-compatible library ID. Must be called before queryDocs to get a valid library ID.
queryDocs	Retrieves and queries up-to-date documentation and code examples from Context7 for any programming library or framework. Requires a Context7-compatible library ID.

Tool Parameters

resolveLibraryId

Required:
  libraryName (string)  — library name to search for, e.g. "react", "nextjs"
  query (string)        — the question or task you need help with (used for ranking)

queryDocs

Required:
  libraryId (string)    — exact Context7 ID, e.g. "/vercel/next.js" or "/vercel/next.js/v14"
  query (string)        — specific question, e.g. "How to set up JWT authentication in Express.js"

Workflow

1. Resolve library ID — get the Context7-compatible ID for the library:

   mh invoke -u https://mcp.context7.com/mcp -t http resolveLibraryId '{"libraryName": "react", "query": "useState hook examples"}'
   

2. Query documentation — use the resolved ID to fetch docs:

   mh invoke -u https://mcp.context7.com/mcp -t http queryDocs '{"libraryId": "/facebook/react", "query": "how to use useState hook"}'
