Claude Code

Context7 integrates with Claude Code to provide current library documentation instead of relying on training data. Set it up with ctx7 setup, or install the Context7 plugin.

Installation#

Run the setup command to configure Context7 for Claude Code:

npx ctx7 setup --claude

This flow authenticates via OAuth, generates an API key, and installs the appropriate skill. You can choose between CLI or MCP mode. Login uses the OAuth device flow — it shows a verification link and short code you open on any device, so it works the same locally or on a remote, headless, or SSH host.

Create or manage API keys in the Context7 dashboard. For manual MCP installation or other configuration options, see All MCP Clients.

Using Context7#

With ctx7 setup, a skill is installed that triggers automatically when you ask about libraries — no need to say “use context7”. You can also invoke it explicitly:

use context7 to show me how to set up a proxy in Next.js 16use context7 for Prisma query examples with relationsuse context7 for the Supabase syntax for row-level security

If you know the library ID, use it directly to skip resolution:

use context7 with /supabase/supabase for authentication docsuse context7 with /vercel/next.js for app router setup

The Context7 Plugin#

The Context7 plugin connects Claude Code to the hosted Context7 MCP server (https://mcp.context7.com/mcp). It adds the resolve-library-id and query-docs tools, with no local Node.js, npm, or npx required.

Installing the Plugin#

The plugin is available from the Context7 marketplace. Run these commands in Claude Code:

/plugin marketplace add upstash/context7/plugin install context7@context7-marketplace

Signing In#

After installing the plugin, restart Claude Code and run /mcp. Select Context7 and follow the browser sign-in flow. No API key is required.
