Frequently asked questions

What is Model Control Protocol (MCP)?

MCP is an Anthropic specification that enables AI models like Claude to interact with external tools and APIs. This server connects AI agents to your Consul infrastructure.

What are the system requirements?

Node.js 18+, npm or yarn, a running Consul instance (local or remote), and Claude Desktop or Cursor IDE with Claude integration.

How do I configure the server for a remote Consul instance with ACL?

Set the `CONSUL_HTTP_ADDR` and `CONSUL_HTTP_TOKEN` environment variables in your configuration, either in a `.env` file or in the MCP server environment settings.

Can I run a demo environment for testing?

Yes, use the provided `./demo/setup-demo.sh` script (requires Docker and Compose) to start a Consul server with demo microservices.

Does the server support stdio and HTTP modes?

Yes. Set `USE_HTTP=true` in the `.env` file for HTTP mode; omit it (or set to false) for stdio mode.
