Cursor AgentDomains delegate_nameservers

How to: Cursor AgentDomains delegate_nameservers

client:Cursor transport:streamable-http tool:delegate_nameservers

Add AgentDomains to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "agentdomains-mcp": {
      "url": "https://mcp.agentdomains.co"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something delegate_nameservers does. Cursor lists the server's tools on connect and calls delegate_nameservers itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that AgentDomains's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Set these first

AgentDomains will not start until these are set, so delegate_nameservers never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
