From the repo.

nameai-mcp

A remote MCP server exposing a handful of name.ai's public, no-auth-required APIs as tools: domain search/availability, WHOIS lookup, TLD registration pricing, and TLD requirements. See src/nameai_mcp/server.py for the tool definitions and src/nameai_mcp/nameai_client.py for the HTTP client that talks to name.ai.

Endpoints

  • GET /health — health check.
  • POST /mcp (and GET /mcp for the SSE stream) — the MCP streamable-http endpoint. This is the URL an MCP client/host connects to.

Configuration

  • NAMEAI_API_BASE_URL — base URL of the name.ai API this server calls. Defaults to https://name.ai.
  • HOST / PORT — bind address for the server itself. Default 0.0.0.0:8000.

Local development

uv sync
uv run uvicorn nameai_mcp.app:app --reload

Docker

docker build -t nameai-mcp .
docker run -p 8000:8000 nameai-mcp

The image runs nameai-mcp (the main() entry point in src/nameai_mcp/__init__.py), which reads HOST/PORT from the environment — pass -e PORT=... if your platform injects a different port.

Deploying

Any host that can run the Docker image works. It is deployed through Coolify on the Hetzner server and served at https://mcp.name.ai/mcp (streamable-http), with Traefik terminating TLS. The original hostname, https://nameai-mcp.h.namekart.com/mcp, still routes to the same container, so client configs written against it keep working.

mcp.name.ai is a DNS-only A record to the Hetzner box. It exists because scanners and MCP tooling look for a server at mcp.<domain> instead of reading the URL out of a manifest — ora's scanner was watched, in this container's own access log, never dialling the manifest's mcpUrl during a scan. Adding a hostname needs two things besides DNS: the domain on the Coolify app, and the host appended to MCP_ALLOWED_HOSTS, without which the SDK's DNS-rebinding guard answers it with 421.

The server calls the public API at NAMEAI_API_BASE_URL, default https://name.ai. Since name.ai moved to Hetzner that resolves to the same host this container runs on, so the calls leave the container, reach the host's own public IP, and come back in through Traefik. That hairpin works here and is left in place deliberately: talking to the API exactly the way an outside client would is the point of this server.

Being reachable isn't the same as being discovered — and that part is done. name.ai advertises this server in four places:

  • https://name.ai/.well-known/mcp.json — manifest
  • https://name.ai/.well-known/mcp/server-card.json — server card
  • https://name.ai/llms.txt — in both the endpoint list and the tool guidance
  • the MCP Registry, namespace ai.name, domain-verified

All four live in the nameaiv1 repo. If the deployed URL changes, they change with it — otherwise agents keep being pointed at the old one.

Config for your environment

Use the endpoint URL below in your config. No API key — you connect directly.

Tool

OS

Config file: ~/.cursor/mcp.json

{
  "mcpServers": {
    "mcp-server": {
      "url": "https://mcp.name.ai/mcp"
    }
  }
}

Paste into mcpServers in the config file. Restart Cursor after saving.

If this MCP is also published on mcpchannel.ai, you can subscribe from Browse and use the gateway config there instead.
