How do I install MCP servers?

Model Context Protocol (MCP) servers are standardized tools defined by Anthropic. If a skill provides an 'npx' installation command, you can run it in your terminal to configure Claude with that tool.

Do these work with Cursor?

Yes, many of the skills in this directory can be copied as .mdc rules into your .cursor/rules directory to instruct the Cursor agent.
