mcp-nats

A Model Context Protocol (MCP) server for NATS messaging system integration

Overview

What is MCP?

The Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs). This server implements the MCP specification to provide NATS messaging capabilities to LLMs and AI applications, allowing them to:

Interact with NATS messaging systems in a standardized way
Safely inspect and monitor NATS servers and streams
Perform read-only operations through a secure interface
Integrate with other MCP-compatible clients and hosts

Features

Server Management (Read-only Operations)
- List and inspect NATS servers
- Server health monitoring and ping
- Server information retrieval
Stream Operations (Read-only Operations)
- View and inspect NATS streams
- Stream state and information queries
- Message viewing and retrieval
- Subject inspection
Multi-Account Support
- Handle multiple NATS accounts simultaneously
- Secure credential management
MCP Integration
- Implements MCP server specification
- Compatible with MCP clients like Claude Desktop
- Standardized tool definitions for LLM interaction
- Safe, read-only operations for AI interaction with NATS
