LLMs rely on outdated or generic information about the libraries you use. You get:
Context7 pulls up-to-date, version-specific documentation and code examples straight from the source — and gives them to your coding agent.
Create a Next.js proxy that checks for a valid JWT in cookies
and redirects unauthenticated users to /login. use context7
Configure a Cloudflare Worker script to cache
JSON API responses for five minutes. use context7
Show me the Supabase auth API for email/password sign-up.
Context7 fetches up-to-date code examples and documentation right into your coding agent's context. No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.
Works in two modes:
ctx7 CLI commands (no MCP required)[!NOTE]
API Key Recommended: Get a free API key at context7.com/dashboard for higher rate limits.
Set up Context7 for your coding agents with a single command. The ctx7 CLI requires Node.js 22.13 or newer.
npx ctx7 setup
Authenticates via OAuth, generates an API key, and installs the appropriate skill. You can choose between CLI + Skills or MCP mode. Use --cursor, --claude, or --opencode to target a specific agent.
To remove the generated setup later, run npx ctx7 remove. If you globally installed the CLI with npm install -g ctx7, remove that package separately with npm uninstall -g ctx7.
To configure manually, use the Context7 server URL https://mcp.context7.com/mcp with your MCP client and pass your API key via the Authorization: Bearer YOUR_API_KEY header. See the link below for client-specific setup instructions.
[Manual Installation / Other Clients →](https://context7.com/docs/resources/all-clients)
If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 can skip the library-matching step and directly retrieve docs.
Implement basic authentication with Supabase. use library /supabase/supabase for API and docs.
The slash syntax tells Context7 exactly which library to load docs for.
To get documentation for a specific library version, just mention the version in your prompt:
How do I set up a Next.js 16 proxy? use context7
Context7 will automatically match the appropriate version.
If you installed via ctx7 setup, a skill is configured automatically that triggers Context7 for library-related questions. To set up a rule manually instead, add one to your coding agent:
Cursor Settings > RulesCLAUDE.mdExample rule:
Always use Context7 when I need library/API documentation, code generation, setup or configuration steps without me having to explicitly ask.
