MCP: Interoperable Tools for Agents

We just expanded Skills and Tools Management with a new section on the Model Context Protocol (MCP) and how it shapes modern agent tooling.

Why This Matters

MCP has shifted from an emerging idea to a shared tool interoperability layer. Instead of wiring every assistant to every system, teams define tools once in MCP servers and let multiple clients discover and use them safely.

What the New Section Covers

• How MCP enables portable tool definitions and safer execution
• Common usage patterns (server catalogs, context stitching, permission-first workflows)
• Adoption notes for Codex, GitHub Copilot, and Claude
• Practical guidance for documenting and versioning MCP tool contracts

Read the Update

Head to Skills and Tools Management to read the new MCP section and see how it fits into tool design, discovery, and best practices.
