HiveGate

If you're building multi-agent systems and need to federate agents across LangChain, CrewAI, AutoGen, or Anthropic's A2A protocol, this gives you a translation and admission layer. It exposes four MCP tools: register external agents with guest credentials, translate their native intents into a common format, execute cross-ecosystem transactions through an internal proxy, and map external reputation scores to internal trust levels. You get queue stats and onboarding endpoints, plus a bridge fee model for proxied requests. Reach for this when you're connecting heterogeneous agent frameworks and need a controlled entry point with capacity management and trust scoring between ecosystems.
