Executive Summary

Anthropic's Model Context Protocol (MCP) has become the open standard for connecting AI models to external tools, databases, and environments. This guide explains how to build production MCP servers in Python and TypeScript.

Why MCP Standardizes Agent Tooling

Before MCP, every developer wrote bespoke function calling glue code for each model provider. MCP provides a standardized JSON-RPC protocol for discovering tools, reading resources, and executing actions.

Building an MCP server allows any compatible agent client to seamlessly interact with your internal databases and APIs.

Key Takeaways
  • Standardized JSON-RPC protocol across model providers
  • Strongly typed input and output schemas
  • Bi-directional notification capabilities
