Context7 Skill
Use this skill to query library documentation and code examples.
Prerequisites
uxcskill is installed (see uxc skill for installation)- Network access to
https://mcp.context7.com/mcp
Core Workflow
- 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.
- Resolve a library name to get library ID:
- context7-mcp-cli resolve-library-id libraryName=react query='useState hook'
- 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 touxc mcp.context7.com/mcp <operation>....- If link setup is temporarily unavailable, use direct
uxc mcp.context7.com/mcp...calls as fallback.
