Permit MCP Gateway is completely free with all essential features included. No paid tiers offered, making it perfect for budget-conscious users.
Model Context Protocol (MCP) enables AI agents to connect to external tools like Salesforce, GitHub, Google Drive, and business systems. Without security controls, agents typically use shared service accounts with broad permissions and no audit trails. Permit adds user identity binding and authorization policies to these connections.
No code changes are required. Permit acts as a transparent proxy - you simply update agent configurations to point to the gateway URL instead of directly to MCP servers. The gateway handles all security enforcement without modifying agent or server code.
Permit offers a free self-serve tier for testing and small deployments with basic features. Enterprise pricing is custom based on agent volume, advanced features, and deployment requirements. On-premises options are available for organizations requiring data residency control.
The gateway supports any OAuth 2.1, OIDC, or SSO provider including Azure AD, Okta, Auth0, Google Workspace, AWS Cognito, and custom identity systems. Integration handles token exchange, session management, and automatic refresh automatically.
Agent fingerprinting requires agents to identify themselves on first connection and continuously monitors their behavior for drift. It prevents shared client sessions, reused permissions, privilege escalation, and unauthorized access by maintaining behavioral baselines and alerting on anomalies.
Yes, Permit's hybrid architecture supports on-premises deployment where the enforcement layer runs in your environment while receiving real-time policy updates from Permit's control plane via OPAL, maintaining data sovereignty while enabling centralized policy management.
It's completely free — no credit card required.
