Context7 CLI (c7)

A simple and convenient command-line interface (CLI) for interacting with the Context7 API.

Quickly search for projects, get information about them, and query specific topics within a project's context, all directly from your terminal. Provides the c7 command.

⚠️ Important: All data provided by this tool comes directly from the official Context7 API (https://context7.com). This tool is simply a convenient wrapper and does not generate or host any content itself.

Features

• Query: Ask questions or request information on specific topics within a project's documentation context.
• Search: Discover available projects indexed by Context7 based on keywords.
• Info: Get metadata about a specific project (like its source repository, last update time, etc.).
• Flexible Output: Get query results in plain text (txt, default) or structured json.
• Save Results: Easily save query output directly to a file (llms_{project}.{format}).
• User-Friendly: Uses spinners for feedback during API calls and colored output for readability.

Installation

Prerequisites

• Node.js (Version 18+ recommended for native fetch, but should work with v16+ if needed)
• npm (usually comes with Node.js) or Bun

Install

npm install -g context7
yarn i -g context7
bun i -g context7

Usage

The basic command structure is:

c7 [command] [arguments...] [options...]

Commands

1. Query (Default Command)

Fetches information about a specific topic within a project. This is the default command if no other command (search, info) is specified.

Syntax:

c7 <projectname> <query...> [options]

Arguments:

• <projectname>: The exact name of the project (e.g., nextjs, react, uv). Use c7 search <term> to find valid names. (Required)
• <query...>: The topic, question, or keywords to query within the project's context. (Required)

Options:

• --type, -t: Specify the output format.
  • txt (Default)
  • json
• --save, -s: Save the output to a file named llms_{projectname}.{format} in the current directory instead of printing to the console. (Boolean flag)
• --tokens, -k: Specify the maximum number of tokens for the API response. (e.g., --tokens 1000). The API default is used if omitted. (Number)

Examples:

# Get info about data fetching in Next.js (default TXT output)
c7 nextjs data fetching strategies

# Get info about state management in React, output as JSON
c7 react state management -t json

# Search for info on installation in the 'uv' project and save to llms_uv.txt
c7 uv installation steps --save

# Query Node.js streams and save the result as llms_nodejs.json
c7 nodejs streams api -t json -s

# Query Next.js data fetching and use only 1000 tokens
c7 nextjs data fetching -k 1000

2. Search

Searches for available Context7 projects based on a keyword in their title. It filters out projects whose internal path contains a /, as these are often duplicates or not directly queryable via this tool.

Syntax:

c7 search <term>

Arguments:

• <term>: The keyword to search for in project titles (e.g., react, python, aws). (Required)

Example:

c7 search next
# Output might look like:
# --- Search Results (Use "Project Name" for queries) ---
#   - Next.js (Project Name: nextjs)
# -------------------------------------------------------
# Example query: c7 nextjs <your query>

3. Info

Displays metadata associated with a specific project.

Syntax:

c7 info <projectname>

Arguments:

• <projectname>: The exact project name (e.g., nextjs, react). Use the name shown in parentheses from the search command results. (Required)

Example:

c7 info react
# Output will show details like Title, Project Name, Docs Source, Last Update, etc.

Getting Help

You can always get help on commands and options:

c7 --help          # General help for all commands
c7 query --help    # Help specifically for the query command (same as default)
c7 search --help   # Help for the search command
c7 info --help     # Help for the info command
