Question 1

What is Model Context Protocol (MCP) and why does my business need it?

Accepted Answer

MCP is the open standard created by Anthropic for connecting AI models to external tools, databases, and business systems securely. Instead of building brittle, custom API wrappers, MCP creates an isolated, interoperable protocol bridge that prevents data leakage and enforces strict permission boundaries.

Question 2

How does an MCP server guarantee that production database data doesn't leak?

Accepted Answer

The MCP server exposes database schemas (table names, column types, foreign keys) without row data. When an LLM generates a SQL query, the MCP server validates it against an AST whitelist, executes it within a sandboxed read-only transaction, and returns only aggregated results or specific answer metrics.

Question 3

Which transports and SDKs do you support?

Accepted Answer

I build production MCP servers using the official FastMCP Python SDK and TypeScript SDKs, supporting both standard input/output (stdio) for local tools (Claude Desktop, Cursor) and Server-Sent Events (SSE) for distributed web applications.

Question 4

Can an MCP server integrate with internal company REST APIs?

Accepted Answer

Yes. An MCP server can wrap internal microservices, CRM APIs, Stripe, Jira, or ERP endpoints, exposing them as safe tools with typed parameters and strict rate-limiting.
