About Permit MCP Gateway

Permit MCP Gateway is a zero-trust security proxy designed to enhance the security and governance of MCP (Meta Cloud Platform) integrations. It seamlessly adds advanced authentication, authorization, and consent management to any MCP server without requiring modifications to existing code or the installation of SDKs or agents. By simply swapping a URL, developers can enable OAuth authentication, Zanzibar-style fine-grained authorization, comprehensive consent screens, and detailed decision logging. This makes it ideal for organizations seeking to secure AI agent connections while maintaining ease of deployment. Its compatibility with any MCP server and focus on augmenting security features make it a compelling choice for developers, security teams, and CISOs looking for a robust, low-overhead security layer.

Pros

  • ✓No SDKs or agents required — easy deployment with URL swap
  • ✓Adds comprehensive security features including OAuth, Zanzibar-style authorization, and consent screens
  • ✓Works with any MCP server, ensuring broad compatibility
  • ✓Full decision logging enhances auditability and compliance
  • ✓Enhances zero-trust security without modifying existing infrastructure

Cons

  • ✗Limited built-in authorization capabilities; relies on external systems for detailed governance
  • ✗No connection to existing IdP infrastructure, which may require additional integration efforts
  • ✗Potential complexity in configuring Zanzibar-style authorization for advanced use cases

Use Cases

1Securing AI agent connections in enterprise MCP environments
2Implementing zero-trust security for internal developer tools
3Adding fine-grained access control and consent flows to existing MCP-based applications
4Ensuring auditability and compliance through detailed decision logging
5Enabling secure integrations for third-party developers without altering core MCP code

Pricing

Likely operates on a subscription or usage-based pricing model, given its role as a security proxy service. Specific pricing details are not publicly available, but it may offer tiered plans based on volume or feature access.
