@sgpdirectory/singapore-business-directory

Official local MCP (Model Context Protocol) package for the SGP Directory remote server. Singapore business directory: search companies, UENs, and SSIC industry classifications.

This package provides a standard stdio interface compatible with local MCP clients (like Claude Desktop and Cursor), proxying requests securely to the remote HTTP streamable SGP Directory server (https://mcp.sgpdirectory.com/mcp).

Usage with Cursor

Run the following package directly using npx:

When configuring Cursor, set the MCP "Type" to command and use:

npx -y @sgpdirectory/singapore-business-directory

Usage with Claude Desktop

Add this to your mcp-servers.json configuration file:

{
  "mcpServers": {
    "sgp-directory": {
      "command": "npx",
      "args": ["-y", "@sgpdirectory/singapore-business-directory"]
    }
  }
}

Authentication

If your proxy is behind an access token, you can pass it via SGP_DIRECTORY_API_KEY environment variable. The wrapper will automatically format it as an Authorization: Bearer <TOKEN> header and attach it to the mcp-remote connection.

You can also override the default remote server URL by setting the REMOTE_MCP_SERVER environment variable.

Example in Claude Desktop

{
  "mcpServers": {
    "sgp-directory": {
      "command": "npx",
      "args": ["-y", "@sgpdirectory/singapore-business-directory"],
      "env": {
        "SGP_DIRECTORY_API_KEY": "your-secret-token",
        "REMOTE_MCP_SERVER": "https://mcp.sgpdirectory.com/mcp"
      }
    }
  }
}

Local Testing

If you have cloned the repository locally, you can run:

This will launch the proxy and wait for standard stdio JSON-RPC messages.
