AgentDomains

Updated October 6, 2026

Overview / Description

AgentDomains is an AI developer tool that provides domain registration and DNS management built for AI agents and automated systems that need to deploy a site or API. It issues free subdomains under makes.fyi and agentdomains.co that an agent can claim and configure instantly, often with a single CLI command that registers the name, adds DNS records, and configures hosting in seconds. It supports A, AAAA, CNAME, and TXT records, each with a unique ID for granular management, and offers three ways to serve content: HTTP URL forwarding that preserves paths, reverse-proxy serving with edge-terminated HTTPS using its own certificate, and nameserver delegation for full control. HTTPS is handled through Let's Encrypt HTTP-01 validation, with DNS-01 challenges available for ACME clients. For automation it exposes a CLI with --json output, an HTTP REST API using Bearer-token auth, and a Model Context Protocol (MCP) server hosted at mcp.agentdomains.co for typed tool calls. For developers comparing AI tools for programmatic domain management, AgentDomains focuses on letting agents get and serve a domain without manual DNS work.
