Registry MCP server

MCP Registry MCP is a server component that provides tools for interacting with the MCP registry system. It offers endpoints for health checks, listing registry entries, retrieving server details, and pinging the server to get configuration information.

Installation and Setup

You can run the MCP Registry MCP server using either Podman or Docker. The following example shows how to configure and run the server as a container.

Using Podman

Create a configuration file with the following JSON content:

{
  "mcpServers": {
    "mcp-registry": {
      "command": "podman",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e", "MCP_REGISTRY_URL",
        "-e", "MCP_TRANSPORT",
        "quay.io/maorfr/mcp-registry-mcp:latest"
      ],
      "env": {
        "MCP_REGISTRY_URL": "https://your-domain.mcp-registry.co",
        "MCP_TRANSPORT": "sse"
      }
    }
  }
}

Make sure to replace "https://your-domain.mcp-registry.co" with the actual URL of your MCP registry.

Using Docker

The configuration is similar for Docker - simply replace the "command": "podman" with "command": "docker":

{
  "mcpServers": {
    "mcp-registry": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e", "MCP_REGISTRY_URL",
        "-e", "MCP_TRANSPORT",
        "quay.io/maorfr/mcp-registry-mcp:latest"
      ],
      "env": {
        "MCP_REGISTRY_URL": "https://your-domain.mcp-registry.co",
        "MCP_TRANSPORT": "sse"
      }
    }
  }
}

Available Tools

The MCP Registry MCP server provides several tools that you can use to interact with the registry:

health_check

Checks the health status of the MCP registry server.

Parameters: None

Example usage:

curl -X POST https://your-server/v1/tools/health_check

list_registry_server_entries

Lists MCP registry server entries with pagination support.

Parameters: None

Example usage:

curl -X POST https://your-server/v1/tools/list_registry_server_entries

get_server_details

Retrieves detailed information for a specific MCP registry server.

Parameters:

• server_id (str): The ID of the server to retrieve details for.

Example usage:

curl -X POST https://your-server/v1/tools/get_server_details \
  -H "Content-Type: application/json" \
  -d '{"server_id": "your-server-id"}'

ping

Simple ping endpoint that returns environment configuration information.

Parameters: None

Example usage:

curl -X POST https://your-server/v1/tools/ping

Environment Variables

The following environment variables can be configured:

• MCP_REGISTRY_URL: The URL of your MCP registry server
• MCP_TRANSPORT: The transport method (e.g., "sse")

Make sure to set these variables correctly in your container configuration.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcp-registry" '{"command":"podman","args":["run","-i","--rm","-e","MCP_REGISTRY_URL","-e","MCP_TRANSPORT","quay.io/maorfr/mcp-registry-mcp:latest"],"env":{"MCP_REGISTRY_URL":"https://your-domain.mcp-registry.co","MCP_TRANSPORT":"sse"}}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "mcp-registry": {
            "command": "podman",
            "args": [
                "run",
                "-i",
                "--rm",
                "-e",
                "MCP_REGISTRY_URL",
                "-e",
                "MCP_TRANSPORT",
                "quay.io/maorfr/mcp-registry-mcp:latest"
            ],
            "env": {
                "MCP_REGISTRY_URL": "https://your-domain.mcp-registry.co",
                "MCP_TRANSPORT": "sse"
            }
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mcp-registry": {
            "command": "podman",
            "args": [
                "run",
                "-i",
                "--rm",
                "-e",
                "MCP_REGISTRY_URL",
                "-e",
                "MCP_TRANSPORT",
                "quay.io/maorfr/mcp-registry-mcp:latest"
            ],
            "env": {
                "MCP_REGISTRY_URL": "https://your-domain.mcp-registry.co",
                "MCP_TRANSPORT": "sse"
            }
        }
    }
}
