Use Valtrinity in AI assistants

AI assistants, coding tools and agents that support the Model Context Protocol (MCP) can connect to Valtrinity and use our tools directly. Every answer links to the full tool page, so a person can check the working or carry on there.

Server address

Add this address as a remote MCP server (the HTTP or Streamable HTTP transport). No account or key is needed.

https://valtrinity.com/api/mcp

Apps that read a JSON settings file usually accept this form:

{
  "mcpServers": {
    "valtrinity": {
      "type": "http",
      "url": "https://valtrinity.com/api/mcp"
    }
  }
}

Tools the server offers

Tool	What it does
search_tools	Finds the right Valtrinity page for a job, from more than 900 tools, and returns the links.
convert_units	Converts length, weight, volume, temperature, speed, pressure, energy, data and more, using exact definitions.
convert_number_base	Converts whole numbers of any length between binary, ternary, octal, decimal and hexadecimal.
dns_lookup	Looks up live A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records for a public domain.

The tools only read information. Each address can make 20 tool calls a day through the server, and a DNS lookup also counts towards the website's daily lookups. The allowance resets at midnight UK time; the same tools on the website are not affected.
