MCP4Humans - Model Context Protocol Client for VS Code

MCP4Humans is a user-friendly VS Code extension that allows you to connect to and interact with Model Context Protocol (MCP) servers directly from your editor. It provides an intuitive interface for managing MCP servers, executing tools, and viewing results.

What is MCP?

The Model Context Protocol (MCP) is an open standard for AI tools and agents to interact with external systems. It enables AI models to access tools, resources, and capabilities beyond their training data, such as:

- Retrieving information from databases or the web
- Executing code
- Accessing file systems
- Interacting with APIs
- And much more
