# MCP Gateway & Registry - Feature Overview

This document provides a comprehensive overview of the MCP Gateway & Registry solution capabilities, designed for stakeholder presentations, marketing materials, and solution demonstrations.

## Core Problem Solved
- **Multi-Platform AI Tool Integration**: Unified gateway for accessing tools across different MCP servers, eliminating the need to manage multiple connections and authentication schemes
- **Centralized Tool Catalog**: Registry acts as a comprehensive catalog of available tools for developers, AI agents, and knowledge workers
- **Dynamic Tool Discovery**: Intelligent routing based on natural language queries and semantic matching, reducing configuration overhead

## Registry & Management
- **Centralized Server Registry**: MongoDB/DocumentDB-backed configuration for all MCP servers and their capabilities
- **Dynamic Tool Catalog**: Real-time discovery of available tools across registered servers
- **MCP Server Version Routing**: Run multiple versions of the same server behind a single gateway endpoint with instant rollback, version pinning, and deprecation lifecycle
- **Custom Metadata**: Add rich custom metadata to servers and agents for organization, compliance, and integration tracking, fully searchable via semantic search
- **Server & Agent Rating System**: 5-star rating widget with aggregate scoring, one rating per user, and rotating buffer
- **Health Monitoring**: Built-in health checks and status monitoring for all registered services
- **Scalable Architecture**: Docker-based deployment with horizontal scaling support

## Agent Registry & A2A Communication
- **A2A Protocol Support**: Agent registration, discovery, and direct agent-to-agent communication
- **Agent Security Scanning**: Integrated scanning using Cisco AI Defense A2A Scanner with YARA pattern matching and heuristic threat detection
- **Agent Discovery API**: Semantic search API for dynamic agent composition at runtime
- **Agent Cards & Metadata**: Rich metadata for agent capabilities, skills, and authentication schemes

## Authentication & Security
- **Multi-Provider OAuth 2.0/OIDC Support**: Keycloak, Microsoft Entra ID, AWS Cognito integration
- **Multi-Provider IAM**: Harmonized API for user and group management across identity providers
- **Static Token Auth**: IdP-independent API access for Registry endpoints using static API keys, designed for CI/CD pipelines and trusted network environments
- **Enterprise SSO Ready**: Seamless integration with existing identity providers including Microsoft Entra ID
- **Service Principal Support**: M2M service accounts with OAuth2 Client Credentials flow for AI agent identity
- **Fine-Grained Access Control**: Scopes define which MCP servers, methods, tools, and agents each user can access
- **Self-Signed JWT Tokens**: Human users can generate tokens for CLI tools and AI coding assistants
- **Secure Token Management**: OAuth token refresh and validation with centralized session management
- **MCP Server Security Scanning**: Integrated vulnerability scanning with Cisco AI Defense MCP Scanner
- **Compliance Audit Logging**: Comprehensive audit logs for all API and MCP access events with TTL-based retention, credential masking, and admin UI for compliance monitoring

## Intelligent Tool Discovery
- **Hybrid Search**: Combined vector similarity with tokenized keyword matching for servers, tools, and agents
- **Semantic Search**: HNSW vector search using sentence transformers or LiteLLM-supported providers
- **Unified Search**: Single endpoint searches across MCP servers, tools, and A2A agents
- **Tag-Based Filtering**: Multi-tag filtering with AND logic for precise tool selection
- **Flexible Embeddings**: Local sentence-transformers, OpenAI, Amazon Bedrock Titan, or any LiteLLM-supported provider
- **Performance Optimized**: Configurable result limits and caching for fast response times

## Developer Experience
- **MCP Registry CLI**: Claude Code-like conversational interface for registry management with real-time token status and cost tracking
- **Registry Management API**: Programmatic API for managing servers, groups, and users with Python client
- **Multiple Client Libraries**: Python agent with extensible authentication
- **Comprehensive Documentation**: Setup guides, API documentation, and integration examples
- **Testing Framework**: 850+ pytest tests (unit, integration, E2E) with GitHub Actions CI
- **Development Tools**: Docker Compose for local development and testing

## Federation & External Registries
- **Peer-to-Peer Registry Federation**: Connect MCP Gateway Registry instances for bidirectional server and agent sync with static token or OAuth2 authentication
- **Federation UI**: VS Code-style Settings page for managing peer registries, sync modes (all, whitelist, tag filter), and monitoring sync status
- **Federated Registry**: Import servers and agents from external registries
- **Anthropic MCP Registry**: Import curated MCP servers with API compatibility
- **Workday ASOR**: Import AI agents from Agent System of Record
- **Automatic Sync**: Scheduled synchronization with external registries and peer registries
- **Amazon Bedrock AgentCore**: Gateway support with dual authentication

## Enterprise Integration
- **Container-Ready Deployment**: Docker Hub images with pre-built containers
- **AWS ECS Production Deployment**: Multi-AZ Fargate deployment with ALB, auto-scaling, CloudWatch, and Terraform
- **Flexible Deployment Modes**: CloudFront Only, Custom Domain with Route53/ACM, or CloudFront + Custom Domain
- **Reverse Proxy Architecture**: Nginx-based ingress with SSL termination
- **DocumentDB & MongoDB CE Storage**: Distributed storage with HNSW vector search
- **Real-Time Metrics & Observability**: Grafana dashboards with SQLite and OpenTelemetry integration
- **Configuration Management**: Environment-based configuration with validation

## Technical Specifications
