MCP Servers and AI Agents

Answer-first: MCP servers make AI agents reliable in production.

AI agents are autonomous systems that observe, reason, act, and repeat. Without structure, agents quickly accumulate permissions, blur responsibilities, and fail unpredictably.

MCP servers define explicit boundaries:

Which actions are allowed
Which tools can be used
How inputs and outputs are handled
What side effects are acceptable
How actions are logged

This allows agents to plan and reason freely, but ensures they operate predictably when acting. Over time, agents become reliable collaborators rather than unpredictable “autonomous entities.”

Takeaway: MCP servers act as the operating system for AI agents, turning them from impressive demos into production-ready systems.
