Article Summary
A tutorial details building an MCP server in Go for database interaction.
- The Model Context Protocol (MCP) server enables AI assistants to execute external tools and access resources, exemplified by database operations.
- The server handles `ToolUse` requests, allowing AI models to query or insert data into a PostgreSQL database using defined tools like `query_db` and `insert_db`.
- Code examples cover server setup with Go, database connection management, and processing MCP tool calls to return `ToolResult` messages.
- The setup emphasizes defining tools via a `tool_definitions.json` file, outlining their input parameters and descriptions for AI assistant consumption.
