InfoBus MCP Server
InfoBus MCP server providing a message bus and event system for AI agents — enabling agents to publish messages to topics, subscribe to events, broadcast information across agent networks, and coordinate between multiple agents via an asynchronous message passing architecture integrated with the MCP protocol.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local in-memory. No external calls. Messages ephemeral. No encryption. Community MCP.
⚡ Reliability
Best When
A multi-agent system needs lightweight event coordination — InfoBus provides a simple pub/sub mechanism for agents to communicate without direct coupling.
Avoid When
You have a single agent, or need production-grade message durability, dead letter queues, or high-throughput messaging.
Use Cases
- • Broadcasting events between multiple concurrent agents from orchestration systems
- • Publishing state changes for other agents to consume from event-driven agents
- • Implementing async coordination between specialized sub-agents from multi-agent systems
- • Distributing work items across agent pool from task distribution agents
- • Building event-driven agent pipelines from workflow automation agents
- • Decoupling agent communication from direct agent-to-agent calls from architecture agents
Not For
- • Single-agent workflows (message bus overhead not needed)
- • High-throughput production messaging (use Kafka, RabbitMQ, or NATS for production)
- • Persistent message queues with durability guarantees (this is lightweight)
Interface
Authentication
No authentication — local in-process message bus. Restrict network access if deployed as a shared service.
Pricing
Free, open source community MCP message bus.
Agent Metadata
Known Gotchas
- ⚠ In-memory message bus — all messages lost on restart; no persistence
- ⚠ No delivery guarantees — messages may be dropped if no subscriber is active at publish time
- ⚠ Community MCP with minimal documentation — implementation quality uncertain
- ⚠ Shared bus state across agents may cause unexpected interactions — design carefully
- ⚠ No dead letter queue or retry mechanism built in
- ⚠ Multi-agent MCP architectures are complex — validate design before building on InfoBus
