Frequently Asked Questions about MCP Servers

What is an MCP server?

MCP vs. OpenAI “function‑calling” — what’s the difference?

Scope: OpenAI function‑calling is an API‑specific JSON protocol that lets ChatGPT call developer‑defined functions inside a single request cycle. MCP is an open, transport‑agnostic protocol that works with any LLM or IDE and supports persistent state, resource streaming and multi‑tool suites.

Transport: Function‑calling occurs over HTTPS. MCP supports STDIO for local processes and Server‑Sent Events for remote servers, enabling CLI‑level latency and bi‑directional progress events.

Security model: Function‑calling inherits the security context of the backend service. MCP adds tool‑level capability descriptors, allowing clients to review & approve each server before use.

Bottom line: choose MCP when you need an open ecosystem where any LLM, IDE or agent framework can reuse the same server; choose function‑calling for quick single‑model prototypes on OpenAI.

Are MCP servers safe to run locally?
Yes—each tool declares required environment variables and permissions up front; clients prompt you to approve before execution. For extra safety, run servers in Docker or point to hosted endpoints.
How does MCP compare to other AI interoperability protocols?
MCP is focused on context and data delivery between AI models and external systems, while protocols like Google’s Agent2Agent (A2A) target agent-to-agent communication. MCP is designed to complement, not replace, other standards in the AI ecosystem.
