Documentation Lookup

Retrieve current documentation and code examples for any library using the Context7 CLI.

Make sure the CLI is up to date before running commands:

npm install -g ctx7@latest

Or run directly without installing:

npx ctx7@latest <command>

Workflow

Two-step process: resolve the library name to an ID, then query docs with that ID.

# Step 1: Resolve library ID
ctx7 library <name> <query>

# Step 2: Query documentation
ctx7 docs <libraryId> <query>

You MUST call ctx7 library first to obtain a valid library ID UNLESS the user explicitly provides a library ID in the format /org/project or /org/project/version.

IMPORTANT: Do not run these commands more than 3 times per question. If you cannot find what you need after 3 attempts, use the best result you have.

Step 1: Resolve a Library

Resolves a package/product name to a Context7-compatible library ID and returns matching libraries.

ctx7 library react "How to clean up useEffect with async operations"
ctx7 library nextjs "How to set up app router with middleware"
ctx7 library prisma "How to define one-to-many relations with cascade delete"

Always pass a query argument — it is required and directly affects result ranking. Use the user's intent to form the query, which helps disambiguate when multiple libraries share a similar name. Do not include any sensitive or confidential information such as API keys, passwords, credentials, personal data, or proprietary code in your query.

Result fields

Each result includes:

• Library ID — Context7-compatible identifier (format: /org/project)
• Name — Library or package name
• Description — Short summary
• Code Snippets — Number of available code examples
• Source Reputation — Authority indicator (High, Medium, Low, or Unknown)
• Benchmark Score — Quality indicator (100 is the highest score)
• Versions — List of versions if available. Use one of those versions if the user provides a version in their query. The format is /org/project/version.
