Frequently asked questions

What is the NATS MCP server?

The NATS MCP server is an Communication Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents publish and subscribe to NATS subjects for lightweight cloud-native messaging. It exposes NATS's capabilities as tools the AI can call directly from your editor or CLI.

How do I install NATS MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install nats` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @nats-io/mcp-server` and restarting Claude Code.

Is NATS MCP free?

Yes. The NATS MCP server is free and open source (see the GitHub repository linked on this page). You may still need a NATS account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does NATS MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
