mcpMethodDefined function

bool? mcpMethodDefined(String method, McpDirection direction, String revision, { Set<String> extensions = const {}, })

Whether method is a protocol method of revision in direction — defined by the core revision, or by an extension in extensions (ids such as io.modelcontextprotocol/tasks). Null when the method is not a protocol method of any supported revision (an application method).

Implementation

bool? mcpMethodDefined(String method, McpDirection direction, String revision,
    {Set<String> extensions = const {}}) {
  var known = false;
  for (final spec in mcpMethods) {
    if (spec.method != method) continue;
    known = true;
    if (spec.direction != direction) continue;
    if (spec.revisions.contains(revision)) return true;
    if (extensions.contains('io.modelcontextprotocol/tasks') &&
        spec.revisions.contains('ext-tasks/$revision')) {
      return true;
    }
  }
  return known ? false : null;
