What is MCP?
The Model Context Protocol (MCP) is an open standard that enables seamless integration between Large Language Models (LLMs) like Claude and external tools, data sources, and services. MCP provides a universal way for AI assistants to interact with your systems, making them more capable and context-aware.
The Problem MCP Solves
Before MCP, connecting LLMs to external tools required custom integrations for each AI provider. This meant:
- Developers had to build separate integrations for ChatGPT, Claude, and other LLMs
- No standard way to expose tools and data to AI assistants
- Limited ability for LLMs to maintain context across different tools
- Complex authentication and security implementations
MCP solves these problems by providing a standardized protocol that any LLM can use to discover and interact with your tools and data.
How MCP Works
MCP operates on a client-server architecture:
- MCP Servers expose tools, resources, and prompts that LLMs can use
- MCP Clients (like Claude) connect to servers and use their capabilities
- The Protocol standardizes how clients and servers communicate
When you create an MCP server, you're essentially creating a bridge between your tools/data and any MCP-compatible LLM.
Core Components of MCP
1. Tools
Tools are functions that LLMs can execute. For example:
- Querying a database
- Sending emails
- Calling APIs
- Performing calculations
2. Resources
Resources provide read-only data that LLMs can access. Examples include:
- Documentation files
- Configuration data
- Real-time sensor readings
- Database schemas
3. Prompts
Prompts are pre-configured templates that help LLMs understand how to use your server effectively. They can include:
- Usage examples
- Best practices
- Common workflows
MCP vs Traditional APIs
| Traditional APIs | MCP |
|---|---|
| Designed for programmatic access | Designed for AI assistant access |
| Requires custom integration per LLM | Works with any MCP-compatible LLM |
| Static request/response | Dynamic tool discovery and execution |
| Limited context awareness | Rich context sharing between tools |
