MCP Servers
Model Context Protocol (MCP) servers are essential components in modern AI systems that manage the context and state of language model interactions. They provide a standardized way to handle model contexts, maintain conversation history, and ensure consistent model behavior across different applications.
Core Concepts
What is an MCP Server?
An MCP server is a lightweight program that exposes specific capabilities through the standardized Model Context Protocol. It acts as a bridge between:
- LLM applications (hosts) [Cursor, Manus]
- Local data sources (files, databases, services)
- Remote services (external APIs)
What Does it do?
MCP servers provide specialized capabilities by bridging AI applications with various tools and services. Here are two key examples:
Database Integration (PostgreSQL Server)
- Schema Inspection: Automatically understand database structure and relationships
- Query Generation: Convert natural language to optimized SQL queries
- Data Analysis: Perform complex analytics while respecting access controls
- Monitoring: Track query performance and resource usage
- Security: Enforce row-level security and column-based access restrictions
GitHub Integration
- Repository Management: Browse, search, and analyze code across repositories
- Code Review: Analyze pull requests and provide intelligent feedback
- Issue Tracking: Manage issues and project boards programmatically
- CI/CD Integration: Monitor and control deployment pipelines
- Collaboration: Interact with comments, discussions, and documentation
These examples highlight the versatile capabilities of MCP servers in modern AI architectures. By providing secure access to sensitive systems, they excel at transforming natural language inputs into concrete actions while maintaining persistent state and context.
