Context7 MCP (Up-to-date docs)
context7-mcp
Always use Context7 MCP to fetch up-to-date library/API documentation before generating code that depends on external libraries or config. Use when the user asks for setup steps, configuration, or code involving third-party libraries. Prefer Context7 docs over memory. Include citations to the ret...

Context7 MCP (Up-to-date docs)
Default behavior
Whenever the task involves any external library/framework:
- Next.js, React, Vite
- Supabase SDK
- PyMuPDF, pdfplumber
- Tailwind, shadcn/ui
- FastAPI, Pydantic
- Anthropic SDK
- Any npm/pip package
Do this:
- Resolve the correct library ID in Context7
- Pull the relevant docs snippet(s)
- Only then generate code/config
- If docs conflict with assumptions, prefer docs
Setup (if not installed)
Remote server (recommended)
claude mcp add --transport http context7 https://mcp.context7.com/mcp --header "CONTEXT7_API_KEY: YOUR_API_KEY"
Local server (npx)
claude mcp add context7 -- npx -y @upstash/context7-mcp --api-key YOUR_API_KEY
API key is optional for basic usage, but helps with rate limits/private repos.
Available tools
resolve-library-id
Find the correct library identifier:
Input: "react" or "fastapi"
Output: library ID to use with get-library-docs
get-library-docs
Fetch documentation for a library:
Input: library ID + optional topic filter
Output: relevant documentation snippets
Usage patterns
Before writing code
1. User asks: "Add Supabase auth to the app"
2. Claude: resolve-library-id("supabase")
3. Claude: get-library-docs(id, topic="authentication")
4. Claude: Generate code based on current docs
When docs conflict with memory
- Always prefer Context7 docs (more recent)
- Mention the source version when relevant
- If uncertain, cite the doc snippet
Recommended rule (add to CLAUDE.md)
"Always use Context7 when I need code generation, setup or configuration steps, or library/API documentation."
Output requirements
When Context7 is used:
- State what library/topic was looked up
- Cite version if available
- Use precise, version-aware steps from docs
