What is an MCP gateway?
An MCP gateway is the enforcement layer every Model Context Protocol tool call passes through with authentication, policy checks, routing, and observability.
Concepts
The Enterprise MCP Gateway
for Every Tool Call
Jarvis Registry is the enterprise MCP gateway - govern, route, and observe every MCP server tool call across your organization. Register any MCP server, federate across AWS AgentCore and Azure AI Foundry, and connect every AI copilot through one authenticated, policy-enforced endpoint.
Components
What's Inside the MCP Gateway
Five core components work together to make every MCP server in your enterprise discoverable, governed, and ready for any AI client or copilot.
Auto-Discovery
Every registered MCP server and its tools discovered via one endpoint - permission-scoped so each AI client sees exactly what it can invoke.
Federation Layer
Cross-cloud MCP registry federation importing servers from AWS AgentCore and Azure AI Foundry into one governed MCP server namespace - no redeployment.
Egress Authentication
Per-user OAuth lifecycle management - tokens encrypted at rest, silently refreshed, and isolated per MCP server per user.
Governance Layer
RBAC scopes and per-tool ACL policies enforced at the MCP gateway uniformly across self-hosted, AgentCore, and Azure AI Foundry MCP servers.
Identity & Observability
On-behalf-of identity propagated through every nested MCP server tool call. OTEL-native traces record tool, identity, and policy snapshot per invocation.
Features
Enterprise-Grade MCP Gateway Capabilities
Everything you need to discover, govern, secure, and observe every MCP server tool call across your enterprise AI stack.
01—Auto-Discovery
One Endpoint. Every MCP Server Auto-Discovered.
Connect any AI copilot or MCP client to a single authenticated gateway endpoint and get automatic discovery of every registered MCP server and its tools - no per-client configuration, no manual server lists. The MCP registry surfaces only the tools each identity is permitted to invoke, giving every client a permission-scoped view of your entire MCP server catalog.
02—Governance Layer
RBAC and ACL Across Every MCP Server
Define role-based access control scopes and per-tool ACL policies that apply uniformly across every MCP server in the catalog - whether self-hosted, federated from AWS AgentCore, or imported from Azure AI Foundry. The MCP gateway enforces policy on every tool call at the gateway layer, not inside individual MCP servers.
03—Identity & Observability
Identity-Bound Calls, Traced End to End
User identity propagates through every nested MCP server tool call so each server in the chain sees who initiated the request. An integrated OTEL collector records the resolved MCP tool, arguments, identity, and policy snapshot on every invocation - ship to Datadog, Grafana, or any OTLP backend without touching your MCP servers.
04—Ingress Auth Conformance
OAuth 2.1 with RFC 8707 Resource Indicators
Every MCP server is an OAuth 2.1 resource server. The MCP gateway sits in front as the protected-resource enforcement point - PKCE mandatory, RFC 8707 resource indicators validated on every token so a credential minted for one MCP server cannot be replayed against another. MCP gateways that haven't implemented RFC 8707 are a full spec revision behind.
05—Egress Authentication
Per-User OAuth Lifecycle Management
The MCP gateway manages the full OAuth credential lifecycle on behalf of each user - tokens are issued, encrypted at rest with AES-256, silently refreshed before expiry, and injected into outbound MCP server calls without ever being surfaced to the calling client. Each user's credentials are isolated per downstream MCP server, so a token compromise is contained to a single server and a single identity.
Multi-Cloud Federation
One MCP Registry Across AWS and Azure
MCP servers deployed in AWS AgentCore and Azure AI Foundry are imported into the Jarvis MCP registry, governed under your access policies, and exposed through a single MCP gateway endpoint - no redeployment, no duplicated infrastructure.
☁ AWS AgentCore
AWS AgentCore Federation
MCP servers deployed in AWS AgentCore are imported into the Jarvis MCP registry, governed under your access policies, and exposed through a single MCP gateway endpoint - no redeployment, no duplicated infrastructure.
- ✓Cross-account IAM via assume-role for secure MCP server discovery across AWS accounts
- ✓Automatic catalog sync brings AgentCore MCP servers into the Jarvis MCP registry
- ✓Inherited governance same RBAC, ACL, and audit trail as native MCP servers
- ✓No redeployment MCP servers continue running inside AgentCore
◈ Azure AI Foundry
Azure AI Foundry Federation
Bring Foundry-hosted MCP servers into the same governed registry as your AWS-native and self-hosted MCP servers. Jarvis handles discovery, lifecycle sync, and access control across the Azure tenant boundary.
- ✓Tenant-scoped discovery across subscriptions and resource groups
- ✓Unified catalog Azure MCP servers alongside AWS and self-hosted servers
- ✓Cross-cloud RBAC applied uniformly regardless of MCP server origin
- ✓One endpoint for all AI clients regardless of which cloud hosts the MCP server
Integrations
Works With Every AI Copilot and MCP Client
Jarvis Registry acts as the universal MCP gateway - connecting any AI client to every registered and federated MCP server through one endpoint.
