This MCP server attempts to exercise all the features of the MCP protocol. It is not intended to be a useful server, but rather a test server for builders of MCP clients. It implements prompts, tools, resources, sampling, and more to showcase MCP capabilities.

## Tools, Resources, Prompts, and Other Features

A complete list of the registered MCP primitives and other protocol features demonstrated can be found in the [Server Features](docs/features.md) document.

## Usage with Claude Desktop (uses [stdio Transport](https://modelcontextprotocol.io/specification/2025-03-26/basic/transports#stdio))

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "everything": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-everything"
      ]
    }
  }
}
```

For manual installation, you can configure the MCP server using one of these methods:

**Method 1: User Configuration (Recommended)**
Add the configuration to your user-level MCP configuration file. Open the Command Palette (`Ctrl + Shift + P`) and run `MCP: Open User Configuration`. This will open your user `mcp.json` file where you can add the server configuration.

**Method 2: Workspace Configuration**
Alternatively, you can add the configuration to a file called `.vscode/mcp.json` in your workspace. This will allow you to share the configuration with others.

> For more details about MCP configuration in VS Code, see the [official VS Code MCP documentation](https://code.visualstudio.com/docs/copilot/customization/mcp-servers).
