MCP Gateway & Registry
An enterprise-ready unified MCP gateway and registry platform that centralizes access to multiple MCP servers with OAuth2 authentication, fine-grained access control, dynamic tool discovery via semantic search, agent-to-agent (A2A) communication, security scanning, and SOC 2/GDPR-ready audit logging.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Gateway for MCP server registry — controls which tools agents can access. Auth depends on deployment model. Treat as infrastructure with high trust requirements.
⚡ Reliability
Best When
You are an enterprise deploying multiple MCP servers to AI agents and need centralized governance, OAuth2-based access control, audit trails, and autonomous tool discovery in a single platform.
Avoid When
You need a simple MCP proxy or are a small team without the infrastructure capacity to run Keycloak, MongoDB, and AWS Fargate.
Use Cases
- • Centralizing enterprise MCP server management with IAM (Keycloak or Microsoft Entra ID), access control, and audit logging for compliance
- • Enabling AI agents to autonomously discover and execute tools across a registered catalog of MCP servers via semantic search
- • Federating multiple registry instances across teams or organizations with bidirectional synchronization and version rollback
Not For
- • Small teams or individual developers — the Keycloak/MongoDB/AWS Fargate stack is heavyweight for simple use cases
- • Teams without DevOps capacity to manage Terraform-based AWS ECS or Docker Compose infrastructure
- • Projects that need a lightweight MCP proxy without governance overhead
Interface
Authentication
Multi-provider IAM with Keycloak and Microsoft Entra ID. Human users authenticate via web login with self-signed JWT for CLI. AI agents use OAuth2 Client Credentials flow. Fine-grained scopes per MCP server, method, tool, and agent.
Pricing
Apache 2.0 licensed. Infrastructure costs depend on deployment (AWS ECS Fargate, MongoDB Atlas, etc.).
Agent Metadata
Known Gotchas
- ⚠ Keycloak setup is non-trivial — misconfigured IAM is the most likely failure point during initial deployment
- ⚠ OAuth2 Client Credentials flow for agents requires pre-registration of each agent identity — not plug-and-play
- ⚠ MongoDB/DocumentDB hybrid search behavior differs between CE and DocumentDB (HNSW) — test in target environment
- ⚠ Terraform-based AWS deployment assumes familiarity with IaC and multi-AZ AWS architecture
- ⚠ Security scanning via Cisco AI Defense requires additional service integration
