What is MCP?
MCP (Model Context Protocol) is an open protocol that enables AI models to securely interact with local and remote resources through standardized server implementations. Think of it as a universal connector between AI assistants and the tools they need.
🔑 Key Concepts
- MCP Servers — Programs that expose tools, resources, and prompts to AI models
- MCP Clients — AI applications (like Claude Desktop) that connect to MCP servers
- Tools — Functions that AI can call (e.g., search the web, query a database)
- Resources — Data sources that AI can read (e.g., files, database records)
How Does MCP Work?
MCP uses a client-server architecture. An AI application (client) connects to one or more MCP servers, each providing specific capabilities. The protocol handles discovery, authentication, and communication between the client and servers.

Popular MCP Servers
The ecosystem is growing rapidly. Some popular categories include:
- Browser Automation — Control web browsers with AI
- Database Access — Query and manage databases
- File Operations — Read, write, and manage files
- Search — Web search and data retrieval
- Communication — Slack, email, and messaging integrations
- AI/ML — Bridge to other AI models and services
Getting Started
1. Install an MCP Client
Download Claude Desktop, Cursor, or any MCP-compatible client.
2. Choose MCP Servers
Browse our directory to find tools that fit your workflow.
3. Configure & Connect
Add server configurations to your client's settings file. Most servers work with just a few lines of config.
