MCP

• let your agent use other people’s developed tools

• examples:
  • context7
  • playwright
• My favorite: postgres MCP
  • demo?
• Capabilities: files, APIs, databases, dev/cloud systems.
• Impact: turns chat into an operational workflow.
• Safety: least privilege, explicit approvals, human review.

Example MCPs (easy -> advanced)

1. Filesystem MCP: read/write project files and generate code changes.
2. GitHub MCP: open issues, inspect PRs, and post review comments.
3. Production Ops MCP: query telemetry, run safe diagnostics, and trigger controlled deploy workflows.

Install MCP (Codex + Claude Code)

• Codex: Settings -> MCP Servers -> Add Server -> provide server command/env -> connect -> verify tools appear.
• Claude Code: configure MCP in ~/.claude/settings.json or project .mcp.json, then restart session and verify tool list.
