Overview

An enterprise zero-trust security gateway, token rate-limiter, and secure SSE proxy for Model Context Protocol (MCP) servers. It is written in JavaScript and acts as a protective layer between MCP clients and servers.

Best for

Teams needing a security and rate-limiting layer for MCP servers over SSE

Use cases

• Secure MCP server endpoints with zero-trust access controls
• Enforce token-based rate limits on MCP API traffic
• Proxy Server-Sent Events from MCP servers through a secure tunnel

Use cases

• Secure MCP server endpoints with zero-trust access controls
• Enforce token-based rate limits on MCP API traffic
• Proxy Server-Sent Events from MCP servers through a secure tunnel

Pros

• Combines gateway, rate limiting, and SSE proxying in one tool
• Zero-trust design targets enterprise security requirements
• Lightweight JavaScript implementation for quick integration

Cons

• No GitHub stars, so community adoption and reliability are unverified
• Vendor listed as ‘Various’, leaving ownership and support unclear
• Description only covers SSE proxying, not other MCP transport methods
