Enterprise-ready MCP Gateway & Registry that centralizes AI development tools with secure OAuth authentication, dynamic tool discovery, and unified access for both autonomous AI agents and AI coding assistants. Transform scattered MCP server chaos into governed, auditable tool access with Keycloak/Entra integration.
The MCP Gateway & Registry is a unified platform designed for centralizing access to both MCP Servers and AI Agents using the Model Context Protocol (MCP). It serves three core functions:
Unified MCP Server Gateway – Centralized access point for multiple MCP servers
MCP Servers Registry – Register, discover, and manage access to MCP servers with unified governance
Agent Registry & A2A Communication Hub – Agent registration, discovery, governance, and direct agent-to-agent communication through the A2A (Agent-to-Agent) Protocol
The platform integrates with external registries such as Anthropic's MCP Registry (and more to come), providing a single control plane for both tool access, agent orchestration, and agent-to-agent communication patterns.
Why unified? Instead of managing hundreds of individual MCP server configurations, agent connections, and separate governance systems across your development teams, this platform provides secure, governed access to curated MCP servers and registered agents through a single, unified control plane.
Transform this chaos:
❌ AI agents require separate connections to each MCP server
❌ Each developer configures VS Code, Cursor, Claude Code individually
❌ Developers must install and manage MCP servers locally
❌ No standard authentication flow for enterprise tools
❌ Scattered API keys and credentials across tools
❌ No visibility into what tools teams are using
❌ Security risks from unmanaged tool sprawl
❌ No dynamic tool discovery for autonomous agents
❌ No curated tool catalog for multi-tenant environments
❌ A2A provides agent cards but no way for agents to discover other agents
❌ Maintaining separate MCP server and agent registries is a non-starter for governance
❌ Impossible to maintain unified policies across server and agent access
Into this organized approach:
✅ AI agents connect to one gateway, access multiple MCP servers
✅ Single configuration point for VS Code, Cursor, Claude Code
✅ Central IT manages cloud-hosted MCP infrastructure via streamable HTTP
✅ Developers use standard OAuth 2LO/3LO flows for enterprise MCP servers
✅ Centralized credential management with secure vault integration
✅ Complete visibility and audit trail for all tool usage
✅ Security features with governed tool access
✅ Dynamic tool discovery and invocation for autonomous workflows
✅ Registry provides discoverable, curated MCP servers for multi-tenant use
✅ Agents can discover and communicate with other agents through unified Agent Registry
✅ Single control plane for both MCP servers and agent governance
✅ Unified policies and audit trails for both server and agent access

Note on Agent-to-Agent Communication: AI Agents discover other AI Agents through the unified Agent Registry and communicate with them directly (peer-to-peer) without routing through the MCP Gateway. The Registry handles discovery, authentication, and access control, while agents maintain direct connections for efficient, low-latency communication.
Unified Agent & Server Registry
This platform serves as a comprehensive, unified registry supporting:
✅ MCP Server Registration & Discovery – Register, discover, and manage access to MCP servers
✅ AI Agent Registration & Discovery – Register agents and enable them to discover other agents
✅ Agent-to-Agent (A2A) Communication – Direct agent-to-agent communication patterns using the A2A protocol
✅ Multi-Protocol Support – Support for various agent communication protocols and patterns
✅ Unified Governance – Single policy and access control system for both agents and servers
✅ Cross-Protocol Agent Discovery – Agents can discover each other regardless of implementation
✅ Integrated External Registries – Connect with Anthropic's MCP Registry and other external sources
✅ Agent Cards & Metadata – Rich metadata for agent capabilities, skills, and authentication schemes
Key distinction: Unlike separate point solutions, this unified registry eliminates the need to maintain separate MCP server and agent systems, providing a single control plane for agent orchestration, MCP server access, and agent-to-agent communication.

What's New
🏷️ Registry Card for Federation Discovery - As registries increasingly need to discover and communicate with each other, we've implemented the Registry Card specification—a standardized discovery document accessible via /.well-known/registry-card. This provides essential metadata including authentication endpoints, capabilities, and contact information for any registry instance. Enhanced server, agent, and skills cards with richer metadata enable better federation workflows. [Registry Card Configuration Guide](docs/federation-operational-guide.m
The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
