🚀 Installation and Usage

1. Install dependencies

cd fsp-mcp-server
npm install

2. Build and run

# Build TypeScript code
npm run build

# Run server
npm start

Or run directly in development mode:

npm run dev

3. Connect to MCP Client

Add the following configuration to your MCP client (e.g., LM Studio, Claude Desktop, etc.):

{
  "mcpServers": {
    "fsp-mcp-server": {
      "command": "node",
      "args": ["/path/to/fsp-mcp-server/dist/index.js"]
    }
  }
}

Replace /path/to/fsp-mcp-server with the actual absolute path to your project directory.

For LM Studio:

Open Settings → Extensions → Model Context Protocol.
Add a new MCP endpoint with the command: node /path/to/fsp-mcp-server/dist/index.js.
Set the transport to stdio.
Save and test the connection via MCP Explorer.

🔧 Configuration

You can customize the server via package.json:

{
  "scripts": {
    "build": "tsc && echo '✅ TypeScript compilation complete: dist/index.js'",
    "build:clean": "npm run build && find dist -name '*.d.ts' -delete && echo '🧹 Cleaned .d.ts files'",
    "dev": "tsx watch src/index.ts",
    "start": "node ./dist/index.js",
    "lint": "eslint \"src/**/*.ts\"",
    "format": "prettier --write ."
  }
}
