Overview

The brex-server MCP Server is a custom TypeScript-based server designed to connect to Brex, implementing a simple notes system that demonstrates core MCP concepts.

To use the brex-server, install the dependencies, build the server, and configure it with Claude Desktop by adding the server config to the appropriate directory based on your operating system.

  • Resources representing text notes with URIs and metadata. - Tools for creating new notes with required title and content parameters. - Prompts for generating summaries of all stored notes, returning structured prompts for LLM summarization.
  1. Creating and managing text notes for various applications.
  2. Summarizing notes for quick reference and review.
  3. Integrating with other applications that support MCP servers.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mcp-brex-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-brex-server-crazyrabbitltc"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "mcp-brex-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-brex-server-crazyrabbitltc"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "mcp-brex-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-brex-server-crazyrabbitltc"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "mcp-brex-server-crazyrabbitltc": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-brex-server-crazyrabbitltc"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mcp-brex-server-crazyrabbitltc": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-brex-server-crazyrabbitltc"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.
