MCP NATS

What it does

This MCP server connects AI models to NATS messaging systems, allowing LLMs to interact with high-performance messaging infrastructure. It enables AI agents to monitor server health, manage streams, and handle key-value stores directly within their context.

Tools

• Server Management: List and inspect NATS servers, monitor health, and measure RTT.
• Stream Operations: View and inspect streams, query state, and retrieve messages.
• Object Store: Create and manage buckets, put/get files, and watch for changes.
• KV Operations: Manage key-value buckets, store/retrieve pairs, and watch updates.
• Publish: Send messages to NATS subjects in various formats.
• Account Operations: View account metrics, generate reports, and manage backups.
