The original title is "Beyond Chatbots: Wrapping My RAG Agent in an MCP Server"

Short summary

The author wraps an existing RAG pipeline into a custom MCP server using FastMCP, exposing four tool categories (calculator, document search, employee leave, ticket info) that AI agents can discover and invoke over HTTP. The RAG search tool was the hardest part because it crosses a real network boundary to a separate FastAPI service, requiring handling of connection failures and response parsing. The author sees MCP as foundational for enterprise AI where agents safely interact with real business capabilities.

• •Built a FastMCP server exposing 4 tool categories including a RAG search endpoint
• •RAG tool calls a separate FastAPI service over HTTP, handling real failure modes
• •Envisions MCP as the tool layer for future multi-agent workflows
