Model Context Protocol (MCP): Database & LLM Integration
How Model Context Protocol (MCP) connects LLMs directly to databases and internal microservices.
Table of Contents
Model Context Protocol (MCP) standardizes secure context exchange between LLMs and external tools, databases, and APIs.
📋 Enterprise System Prompt Template
Deterministic JSON output prompt template for production LLM pipelines:
<system_instructions>
<role>Sen kıdemli bir kurumsal veri ve otomasyon mimarisisin.</role>
<rules>
1. Yalnızca verilen bağlama sadık kal, eksik verileri null ata.
2. Yanıtı saf JSON şemasında döndür.
</rules>
<output_schema>{ "intent": "sales | support", "status": "verified" }</output_schema>

What is Model Context Protocol (MCP) and why is it significant?
MCP is an open standard introduced by Anthropic that provides a unified JSON-RPC 2.0 interface for connecting LLMs to databases, file systems, and enterprise APIs, replacing fragmented custom integration code with a standardized client-server protocol.
How does MCP differ from Retrieval-Augmented Generation (RAG)?
RAG retrieves pre-computed vector embeddings from static knowledge documents, whereas MCP grants LLMs real-time, interactive read and write access to live transactional databases and APIs. Modern architectures frequently combine both approaches.
How is database security enforced when integrating LLMs via MCP?
Security is maintained by assigning read-only database credentials by default, exposing strictly scoped tool definitions, requiring Human-in-the-Loop authorization for write/delete queries, and maintaining immutable audit logs of all tool calls.
What are the core primitive capabilities defined in the MCP specification?
The MCP specification defines three core primitives: Resources (passive data context read by the LLM), Prompts (pre-configured prompt templates), and Tools (executable functions the LLM can invoke to perform external operations).
What transport layers does Model Context Protocol support?
MCP supports standard input/output (stdio) for local process communication and Streamable HTTP with Server-Sent Events (SSE) for remote network connections.
