The gate your AI agents pass through.
MCP is the door your AI agents walk through to reach your systems. ModGate is the bouncer — checking every ID, logging every entry, revoking access instantly.
Free plan includes 500 authentications/mo. No credit card required.
MCP is the door between agents and your systems.
41% of those doors have no locks.
The Model Context Protocol has become the universal standard for AI agents connecting to the real world. But the infrastructure to secure it barely exists.
The bouncer and the building — in one.
Most companies rent you the building. ModGate gives you the bouncer, the ID system, and the security cameras. Enforced automatically from day one.
The building
Push your MCP server to ModGate with one command. OAuth 2.1 with PKCE is enforced automatically — no auth configuration required.
The bouncer
Every agent gets a named identity, scoped credentials, and per-tool access policies. Tokens are short-lived, audience-bound, and revocable instantly.
The security camera
Every tool call, every token issuance, every access decision — logged, searchable, and exportable. Know exactly what your agents did and when.
Four layers of protection.
OAuth 2.1 proxy
The hard part, done.
- PKCE with S256 — mandatory for all HTTP transports
- Dynamic Client Registration out of the box
- /.well-known discovery endpoint auto-configured
- Audience binding prevents token replay attacks
- Works with Okta, Entra ID, Clerk, Auth0
Agent identity system
Agents aren't users. Treat them differently.
- Named agent credentials — not just "API key #47"
- Per-tool scope policies — read yes, delete no
- Cross-agent delegation (xAA) — orchestrators spawn scoped sub-agents with cryptographically verified chains
- Short-lived tokens with non-interactive refresh
- One-click revocation — kill any agent instantly
Continuous authorization
Not just at login. Every request.
- Live revocation — a killed agent is rejected on its very next call, not at token expiry
- Admin force-reauth kill switch — invalidate every outstanding token for an agent instantly
- Configurable reverification windows — cap session age independent of token TTL
- Per-agent rate-anomaly detection — abnormal call bursts blocked automatically
- This is what turns ModGate from an auth layer into a security layer
Audit & compliance
Know exactly what your agents did.
- Every tool call logged with agent identity + timestamp
- Searchable, filterable, exportable audit log
- Real-time webhooks — HMAC-signed events for denials, revocations, and anomalies
- SOC 2 ready from day one
- GDPR-compliant EU data residency available
Three buyers. One problem.
Adding AI agents to your product? You need multi-tenant auth and tool-level scoping for every customer. ModGate handles it without you building the infrastructure.
Running 1,000+ agent executions a week? You need governance, auditability, and SSO before any of this goes near production. Your CISO requires it.
Hit the auth wall moving from prototype to production? You're not alone — 58% of MCP servers have no auth at all. ModGate is the on-ramp to production-grade.
