Frontal MCP Server

A standalone Model Context Protocol (MCP) server that provides seamless access to Frontal's cloud services (AI, Blob Storage, Functions, Graph Database, and Pipelines) through a standardized interface.

Quick Start

Installation

# Install globally
npm install -g @frontal-labs/mcp-server

# Or install locally
npm install @frontal-labs/mcp-server

Basic Setup

1. Get your API key from Frontal Dashboard

2. Set up environment:

export FRONTAL_API_KEY="your_api_key_here"

3. Start the server:

# For Claude Desktop (stdio transport)
frontal-mcp-server --transport stdio

# For web applications (HTTP transport)
frontal-mcp-server --transport http --port 3000

Claude Desktop Integration

Add to your Claude Desktop configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "frontal": {
      "command": "frontal-mcp-server",
      "args": ["--transport", "stdio"],
      "env": {
        "FRONTAL_API_KEY": "your_api_key_here"
      }
    }
  }
}

Usage Examples

Basic Usage

# Start with stdio transport (for Claude Desktop)
FRONTAL_API_KEY=your_key ./dist/bin/frontal-mcp-server.js

# Start with HTTP transport for web integration
FRONTAL_API_KEY=your_key ./dist/bin/frontal-mcp-server.js --transport http --port 3000

# Enable only specific services
ENABLE_AI=true ENABLE_BLOB=false ./dist/bin/frontal-mcp-server.js

Programmatic Usage

import { FrontalMcpServer, createLogger } from '@frontal-labs/mcp-server';

const config = {
  apiKey: 'your_api_key',
  transport: { transport: 'stdio' },
  services: {
    ai: true,
    blob: true,
    functions: false,
    graph: false,
    pipelines: false,
  }
};

const logger = createLogger({ level: 'info' });
const server = new FrontalMcpServer(config, logger);

await server.initialize();
await server.connectStdio();

Architecture

The MCP Server follows a modular adapter pattern:

1. Core Server: Handles MCP protocol and transport management
2. Service Adapters: Each Frontal service has its own adapter
3. Configuration: Centralized config with environment variable support
4. Transport Layer: Supports both stdio and HTTP transports

Troubleshooting

Common Issues

Server won't start:

# Check API key
echo $FRONTAL_API_KEY

# Validate configuration
frontal-mcp-server --validate-config

Connection issues:

# Test with different transport
frontal-mcp-server --transport http --port 3000

# Check logs
frontal-mcp-server --verbose

Performance issues:

# Enable debug logging
MCP_LOG_LEVEL=debug frontal-mcp-server

# Monitor resources
top -p $(pgrep frontal-mcp-server)
