getRegisteredToolFields

List<String> getRegisteredToolFields(

String toolName

)

Returns the field names exposed in the Zod input schema for a registered tool. This is what MCP clients see when inspecting a tool's parameters. Returns an empty list if the tool is not found or has no schema fields.

Implementation

List<String> getRegisteredToolFields(String toolName) {
  try {
    final registeredTools = _mcpServer['_registeredTools'] as JSObject?;
    if (registeredTools == null) return [];
    final tool = registeredTools[toolName] as JSObject?;
    if (tool == null) return [];
    final inputSchema = tool['inputSchema'] as JSObject?;
    if (inputSchema == null) return [];
    final shape = inputSchema['shape'] as JSObject?;
    if (shape == null) return [];
    final keys = _jsObjectKeys(shape);
    return [for (var i = 0; i < keys.length; i++) keys[i].toDart];
  } catch (_) {
    return [];
  }
