What is Golf
Golf, launched in 2025, is both a security firewall and an open-source framework designed for enterprises deploying MCP servers. As a protocol-aware security layer, it acts as a protective barrier between AI agents and MCP servers, providing centralized security controls, governance, and observability. The platform combines a high-performance security firewall with a developer-friendly framework that simplifies the creation of MCP server applications by allowing developers to define tools, prompts, and resources as simple Python files.
Key Features of Golf
Golf is a protocol-aware security firewall designed specifically for Model Context Protocol (MCP) servers. It acts as a centralized control point that provides comprehensive security features including authentication, authorization, threat protection, audit logging, and policy enforcement. The system helps enterprises secure their MCP infrastructure by protecting against specific threats like prompt injection and token hijacking while offering unified monitoring and governance capabilities.
Protocol-Aware Security: Provides specialized protection against MCP-specific threats including prompt injection, token hijacking, command injection, and tool spoofing through intelligent traffic inspection
Centralized Policy Management: Offers a single dashboard to manage security policies, CORS settings, and security headers across all MCP servers in the infrastructure
Comprehensive Audit System: Maintains detailed audit trails of all requests/responses with complete data flow tracing and unified threat dashboard for monitoring security events
Role-Based Access Control: Implements sophisticated RBAC with fine-grained token validation and rate limiting to protect backend resources from abuse
Use Cases of Golf
Enterprise MCP Security: Large organizations can secure their AI infrastructure by implementing Golf as a master security layer for all their MCP servers
Regulated Environment Compliance: Organizations in regulated industries can use Golf to maintain compliance through comprehensive audit trails and centralized policy enforcement
Development Operations: Development teams can use Golf's framework to quickly build and deploy production-ready MCP servers with built-in security features
Pros
Unified security control and monitoring across all MCP servers
Production-ready with enterprise-grade features and scalability
Self-hosting option available for complete control over data
Cons
Requires additional infrastructure layer in MCP stack
May introduce slight latency due to proxy architecture
How to Use Golf
Create new project: Create a new directory with basic project structure using Golf's project creation command. This will set up example tools, resources, and a golf.json configuration file.
Configure golf.json: Set up the main configuration file golf.json with server name, port, transport, telemetry and other build settings.
Set up authentication: Configure authentication in auth.py using supported methods like JWT, OAuth Server, API keys, or development tokens.
Implement tools: Create tool implementations in the /tools directory to define the functionality you want to expose through your MCP server.
Add resources: Implement resources in the /resources directory that your tools will utilize.
Define prompts: Create prompt templates in the /prompts directory to standardize interactions.
Configure environment: Set up environment variables in .env file for API keys, server port and other sensitive configuration.
Start development server: Launch the Golf development server to test your MCP implementation locally.
Deploy to production: Once tested, deploy your Golf MCP server to production with built-in security controls and monitoring.
Monitor and manage: Use Golf's unified dashboard to monitor traffic, enforce security policies, and manage your MCP infrastructure.
