Use when you need current, version-specific documentation for npm packages, Python libraries, or other programming languages. metadata: short-description: Query library docs via Context7 MCP

Context7 Skill

Use this skill to query library documentation and code examples.

Prerequisites

• uxc skill is installed (see uxc skill for installation)
• Network access to https://mcp.context7.com/mcp

Core Workflow

1. Use fixed link command by default:

   • command -v context7-mcp-cli
   • If missing, create it: uxc link context7-mcp-cli mcp.context7.com/mcp
   • context7-mcp-cli -h
   • If command conflict is detected and cannot be safely reused, stop and ask skill maintainers to pick a different fixed command name.

2. Resolve a library name to get library ID:

   • context7-mcp-cli resolve-library-id libraryName=react query='useState hook'

3. Query documentation:

   • context7-mcp-cli query-docs libraryId=/reactjs/react.dev query='how to use useState'

Available Tools

• resolve-library-id: Resolve a package/library name to Context7 library ID
• query-docs: Query documentation and code examples for a specific library

Usage Examples

Find React documentation

# First resolve the library
context7-mcp-cli resolve-library-id libraryName=react query='React useState hook'

Query specific documentation

context7-mcp-cli query-docs '{"libraryId":"/reactjs/react.dev","query":"how to use useEffect"}'

Query Node.js documentation

context7-mcp-cli resolve-library-id libraryName=node query='file system'

Notes

• Requires library name first, then use the returned libraryId for queries
• Context7 provides version-specific, up-to-date documentation
• Supports npm packages, Python libraries, and more
• context7-mcp-cli <operation> ... is equivalent to uxc mcp.context7.com/mcp <operation> ....
• If link setup is temporarily unavailable, use direct uxc mcp.context7.com/mcp ... calls as fallback.
