Domain search MCP server

MCP server

One address gives any MCP client five domain tools. It needs no key and no sign-in, so it works as a plain custom connector.

The server

Transportstreamable HTTP
JSON-RPC over POST to one address. Plain JSON answers; no event stream is needed.
Sign-innone
No key, no OAuth. Choose no authentication where a client asks.
SessionMcp-Session-Id
Given on the first answer. Clients send it back, and pacing is counted per session.
Tools5
check_domains, search_name, suggest_names, domain_details and ending_prices. All read only.

Any other client

Most clients take the address and nothing else. One that wants a config file usually takes this shape, with url, serverUrl or httpUrl as the key depending on the client:

mcp.json
{
  "mcpServers": {
    "domainmcp": {
      "url": "https://domainmcp.net/mcp"
    }
  }
}

To see it answer without a client, list its tools:

Terminal
curl -X POST "https://domainmcp.net/mcp" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "tools/list"}'
