It validates the domain, fetches DNS records from DNSDumpster API using the client, extracts TXT records, formats them, and returns as a string. Includes the @mcp.tool() decorator which registers it as an MCP tool.@mcp.tool() async def get_txt_records(domain: str, ctx: Context) -> str: """Get TXT records for a domain.
