• src/tools/converters.ts:99-162 (handler)

  The tool 'number_base_convert' is registered and implemented within the same `server.tool` call in `src/tools/converters.ts`.

  server.tool(
    "number_base_convert",
    "Convert a number between different bases (binary, octal, decimal, hexadecimal, or any base 2-36).",
