Installation

Prerequisites

Node.js installed on your system
Access to a Consul server (local or remote)

Installing via Smithery

The easiest way to install Consul MCP Server for Claude Desktop is via Smithery:

npx -y @smithery/cli install @kocierik/consul-mcp-server --client claude

Manual Installation

Clone the repository or download the source code
Install dependencies:
```
npm install
```
Build the project:
```
npm run build
```

Configuration

The server can be configured using environment variables:

CONSUL_HOST: Consul server host (default: localhost)
CONSUL_PORT: Consul server port (default: 8500)

Usage

Starting the Server

Start the server with:

node build/index.js

The server will connect to Consul and make all functionality available through the MCP interface.

Claude Configuration

To use the Consul MCP Server with Claude, add the following configuration to your Claude config:

{
    "mcpServers": {
        "consul-mcp": {
            "command": "node",
            "args": [
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER/consul-mcp-server/build/index.js"
            ]
        }
    }
}

Be sure to replace the path with the absolute path to the build/index.js file on your system.

Testing the Server

To verify that the server is working correctly, you can run the MCP inspector:

npx @modelcontextprotocol/inspector node build/index.js

This will perform a health check and show you the available capabilities of your Consul MCP Server.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
