Commands

search — browse available libraries

context7 search <library>

context7 search react
# {"ok":true,"data":[{"id":"/websites/react_dev","name":"React","description":"..."},…]}

With full metadata:

context7 search react --detail full
# {"ok":true,"data":[{"id":"/websites/react_dev","name":"React","description":"...","totalSnippets":2922,"trustScore":10,"benchmarkScore":95.1,"versions":[]},…]}

docs — fetch documentation

Accepts a library name (auto-resolves) or ID (direct lookup).

context7 docs <name-or-id> [--topic T] [--tokens N] [--detail concise|full]

# By name (auto-resolves to best match)
context7 docs nextjs --topic routing

# By ID (skips resolution)
context7 docs /vercel/next.js --topic routing

# Limit token budget
context7 docs nextjs --tokens 2000

# Full metadata (type, tokens, language per snippet)
context7 docs nextjs --topic hooks --detail full

Concise response (default):

{
  "ok": true,
  "library": "Next.js",
  "libraryId": "/vercel/next.js",
  "data": [
    { "title": "App Router > Routing", "content": "..." }
  ]
}

Full response (--detail full):

{
  "ok": true,
  "library": { "id": "/vercel/next.js", "name": "Next.js", "snippets": 2922, "trustScore": 10 },
  "data": [
    { "title": "App Router > Routing", "content": "...", "type": "code", "tokens": 450, "language": "typescript" }
  ]
}

Truncation — when results exceed the token budget, a steering message is appended:

{
  "truncated": "Result truncated at 2000 tokens. 3 more snippets available. Use --tokens 4000 or --topic to narrow results."
}

Flags

| Flag | Description | Default | |------|-------------|---------| | --api-key <key> | Context7 API key (or set CONTEXT7_API_KEY env var) | — | | --topic <topic> | Focus docs on a specific topic | "documentation" | | --tokens <number> | Token budget for docs response | 10000 | | --detail <concise\|full> | Response detail level | concise | | --help | Show help | — |

Authentication

Optional. Set CONTEXT7_API_KEY for higher rate limits:

export CONTEXT7_API_KEY=your-key-here
