mcp-server-subreg

MCP server exposing the Subreg.cz domain registrar SOAPAPI — via the subreg-clientlibrary — as tools for LLM agents built with FastMCP.

Configuration

Credentials are read from the environment only, never accepted as toolparameters:

Variable	Required	Description
`SUBREG_LOCATION`	yes	SOAP endpoint, e.g. `https://soap.subreg.cz/cmd.php`
`SUBREG_URI`	yes	SOAP namespace URI, e.g. `https://soap.subreg.cz/soap`
`SUBREG_LOGIN`	yes	Subreg account login
`SUBREG_PASSWORD`	yes	Subreg account password
`SUBREG_READONLY`	no	`true` (default) blocks mutating tools; set to `false` to allow domain/DNS/contact/billing writes

Use https://ote-soap.subreg.cz/... endpoints for Subreg's OTE sandboxenvironment while testing.
