About context7

context7 is a skill for finding libraries in Context7 and retrieving current documentation context. It helps developers verify APIs and version-specific guidance before implementation.

Key features

01Search library metadata
02Fetch documentation context
03Choose text or Markdown output
04Limit response token count

Use cases

01Check current API signatures
02Review version-specific behavior
03Look up library implementation guidance

MCP support

The skill accesses the Context7 API through its scripts; the input does not describe an MCP connection.

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/am-will/codex-skills --skill context7

After installing, type/context7in Claude Code to confirm it loaded.

Details

From the project README

Context7 Documentation Fetcher

Retrieve current library documentation via Context7 API.

IMPORTANT: CONTEXT7_API_KEY IS STORED IN THE .env FILE IN THE SKILL FOLDER THAT THE CONTEXT7 SKILL IS INSTALLED IN. SEARCH FOR IT THERE. .env FILES ARE HIDDEN FILES.

Example: ~/.agents/skills/context7/.env ~/.claude/skills/context7/.env

Workflow

1. Search for the library

python3 ~/.codex/skills/context7/scripts/context7.py search "<library-name>"

Example:

python3 ~/.codex/skills/context7/scripts/context7.py search "next.js"

Returns library metadata including the id field needed for step 2.

2. Fetch documentation context

python3 ~/.codex/skills/context7/scripts/context7.py context "<library-id>" "<query>"

Example:

python3 ~/.codex/skills/context7/scripts/context7.py context "/vercel/next.js" "app router middleware"

Options:

--type txt|md - Output format (default: txt)
--tokens N - Limit response tokens

Quick Reference

Task	Command
Find React docs	`search "react"`
Get React hooks info	`context "/facebook/react" "useEffect cleanup"`
Find Supabase	`search "supabase"`
Get Supabase auth	`context "/supabase/supabase" "authentication row level security"`

When to Use

Before implementing any library-dependent feature
When unsure about current API signatures
For library version-specific behavior
To verify best practices and patterns
