Overview

What is NATS MCP toolbox?

A collection of CLI tools that expose MCP (Model Context Protocol) tools via NATS microservices. It can be used standalone to expose local or existing MCP servers over NATS, or as a Go library to expose functionality as tools.

How to use NATS MCP toolbox?

Run ./nats-mcp tool --url <nats-server> --command <mcp-server-binary> [args] to expose an existing MCP server via NATS. Use ./nats-mcp client list --url <nats-server> to list available tools. Configure a local agent by adding ./nats-mcp server --url <nats-server> to your MCP config. The NATS_URL environment variable sets the default NATS server URL.

Run the command: `./nats-mcp tool --url <nats-url> --command <path-to-mcp-server> [args]`.

3

How do I list available tools on a NATS server?

Use: `./nats-mcp client list --url <nats-url>`.

4

How do I use it with my local agent?

Add `./nats-mcp server --url <nats-url>` to your MCP client configuration so the agent can connect to NATS‑exposed tools.
