name: context7 description: Retrieve up-to-date documentation for software libraries, frameworks, and components via the Context7 API. Use when looking up documentation for any programming library or framework, finding code examples for specific APIs or features, verifying correct usage of library functions, or obtaining current information about library APIs that may have changed since training.

Context7

Fetch current documentation for software libraries via Context7 API.

Setup

API key stored in .env.local as CONTEXT7_API_KEY. Read the key value directly and use it in curl commands.

Usage

Important: Use curl commands directly with the API key value (not shell variables). This ensures permission rules like Bash(curl:*) can match and auto-execute.

Step 1: Search for library ID

bash

curl -s -H "Authorization: Bearer <API_KEY>" "https://context7.com/api/v2/libs/search?libraryName=LIBRARY&query=TOPIC" | jq -r '.results[0].id'

Step 2: Fetch documentation

bash

curl -s -H "Authorization: Bearer <API_KEY>" "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=TOPIC&type=txt"

Notes

•Read API key from .env.local and substitute directly into commands
•Do NOT use export, source, or ${} variable expansion - these create complex commands that won't match permission rules
•Use type=txt for readable output
•URL-encode spaces as + or %20
•Common library IDs: /websites/react_dev, /vitejs/vite, /tailwindlabs/tailwindcss.com, /tanstack/query, /shadcn-ui/ui
