Documentation Lookup

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

Run commands with npx ctx7@latest so setup always uses the latest CLI without a global install:

npx ctx7@latest library <name> "<query>"
npx ctx7@latest docs <libraryId> "<query>"

Optionally install globally if you prefer a bare ctx7 command:

npm install -g ctx7@latest

Workflow

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

# Step 1: Resolve library ID
npx ctx7@latest library <name> "<query>"

# Step 2: Query documentation
npx ctx7@latest docs <libraryId> "<query>"

You MUST call 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.

npx ctx7@latest library React "How to clean up useEffect with async operations"
npx ctx7@latest library "Next.js" "How to set up app router with a proxy"
npx ctx7@latest library Prisma "How to define one-to-many relations with cascade delete"

Use the official library name with proper punctuation (e.g., "Next.js" not "nextjs", "Customer.io" not "customerio", "Three.js" not "threejs"). If results look wrong, try alternate spellings such as next.js before changing the query.

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.
