agentgateway vs mcp-observatory
agentgateway: Agentgateway is an open-source proxy offering a complete connectivity solution for Agentic AI, built on AI-native protocols like MCP and A2A. It provides security, observability, and governance for agent-to-LLM, agent-to-tool, and agent-to-agent communication across various frameworks.; mcp-observatory: MCP Observatory is a comprehensive tool designed to ensure the reliability and security of Model Context Protocol (MCP) servers. It integrates with GitHub CI/CD to provide automated testing, schema drift detection, and security analysis, generating actionable evidence for maintainers and AI agents.

TL;DR
agentgatewayObservability · ★ 5.7k
When to choose:
- You want one proxy for LLM calls (OpenAI-compatible API with spend controls, failover and load balancing), MCP tools and A2A traffic.
- You need guardrails from several sources: regex, OpenAI moderation, AWS Bedrock Guardrails, Google Model Armor or webhooks.
- You need security and observability built in: JWT, API keys, OAuth, RBAC with a CEL policy engine, rate limiting, TLS and OpenTelemetry.
When to skip:
- You only need to bridge one MCP transport: a small proxy is simpler.
- You want the inference-routing features without Kubernetes: the README ties them to Kubernetes Inference Gateway extensions.
- You want detailed setup instructions in the README: it is short and points to the documentation site.
