MCP vs Agent Skills: What's the Difference and Which Do You Need?

Short summary

MCP (Model Context Protocol) provides AI assistants live access to data sources; Agent Skills teach coding assistants to perform tasks correctly. Together they enable developers to build with both real-time context and accurate code generation—Cosmic ships both natively.

  • •MCP = standardized data access layer allowing AI models to connect to external tools and databases
  • •Agent Skills = task knowledge teaching AI coding assistants how to work correctly with specific platforms
  • •Using both together provides live data context plus correct code generation—the most powerful setup

Generated with AI, which can make mistakes.
