MCP security gateway for AI, providing authentication, fine-grained authorization, consent, and audit.
MCP enables AI agents to connect to your tools, but its built-in authentication is limited: no granular authorization, governance, or integration with your existing IdP infrastructure. The Permit MCP Gateway is a zero-trust proxy that bridges these gaps for any MCP server without modifying its code. Change one URL, and every tool call gets OAuth 2.1 authentication, fine-grained authorization (RBAC, ABAC, ReBAC), customizable consent screens, and full decision logging. No SDKs to install, no agents to rewrite. Compatible with any MCP server, including Salesforce, GitHub, Slack, Google Drive, Jira, etc. Offers real-time visibility, intelligent detection of risky behavior, and enterprise-grade security.
For software developers, Permit MCP Gateway enables secure access to AI coding assistants like Cursor or Claude. This prevents unauthorized data exfiltration by ensuring every code suggestion or query is tied to the developer's verified identity and explicit consent, maintaining compliance and security.
For solopreneurs managing client projects, Permit MCP Gateway allows AI agents to interact with tools like Google Drive or Notion securely. This ensures that client data accessed by AI is governed by explicit consent and logged, preventing accidental data leaks and maintaining client trust.
For team leads overseeing AI agent workflows, Permit MCP Gateway provides real-time visibility and control over AI interactions with tools like Jira or Slack. This allows for the enforcement of least privilege, preventing AI agents from performing unintended actions and ensuring all activities are auditable for compliance.
For security analysts, Permit MCP Gateway offers a comprehensive audit trail of all AI agent actions across various MCP-enabled tools. This enables the detection of risky behavior or prompt drift by providing detailed logs of who, what, when, and why for every tool call, facilitating incident response and policy refinement.
Permit MCP Gateway offers a free 'Community' tier that includes all authorization models, up to 1,000 MAU, embeddable interfaces, and community Slack support. This tier is free forever and does not require a credit card.
Permit MCP Gateway has a 'Pro' tier starting at $25 per month, which supports up to 50,000 MAU and includes features like GitOps CI/CD and OAuth 2.1 proxy. An 'Enterprise' tier with custom pricing is available for unlimited MAU and advanced features like HIPAA BAA, GDPR, CCPA, and SOC 2 compliance.
Permit MCP Gateway is designed with security in mind, offering features like OAuth 2.1 proxy and Zanzibar-style authorization. The Enterprise tier explicitly mentions compliance with GDPR, CCPA, and SOC 2, indicating a focus on data privacy and security standards.
While Permit MCP Gateway focuses on securing AI agent connections to MCP servers, alternatives for broader authorization needs include solutions like Oso, Casbin, and systems that integrate with FGA/Google Zanzibar like AuthZed or Ory Keto. The best alternative depends on specific requirements for policy engines and integration.
The Permit MCP Gateway is a zero-trust proxy that acts as a security layer between AI agents and MCP servers. It provides OAuth authentication, granular authorization, consent screens, and audit logging without requiring code changes to existing MCP servers or AI agents.
Yes, Permit MCP Gateway supports multi-tenancy, allowing for the management of multiple tenants and environments. The Pro tier supports up to 20,000 tenants and 50 environments, while the Enterprise tier offers unlimited tenants and environments.
Permit MCP Gateway supports all authorization models, including RBAC, ABAC, and ReBAC. It acts as a transparent proxy, enforcing fine-grained policies for every tool call made by AI agents, ensuring only authorized actions are permitted.
