September 2026 release notes for Maestro in Automation Cloud and Test Cloud.

Configure e gerencie ferramentas MCP diretamente no fluxo

No Maestro Flow, os nós de Agentes autônomos agora são compatíveis com um controle mais rico sobre ferramentas de Protocolo de contexto do modelo (MCP). Você pode editar descrições por argumento, visualizar o esquema completo de entrada e saída de uma ferramenta e escolher como cada argumento obtém seu valor: o agente decide no runtime, é associado a uma variável de agente ou é um valor fixo que pode ser marcado como confidencial. Os servidores MCP agora também expõem uma ação explícita de Atualizar ferramentas, em vez de descobrir ferramentas automaticamente, e podem extrair sua lista de ferramentas em tempo real do Agent Hub.

Para obter mais informações, consulte Agente.

Keep MCP tool schemas up to date automatically

MCP (Model Context Protocol) tools added to an Agent node in Maestro Flow can drift out of date if the underlying MCP server's tool definition changes after you configure it — for example, a parameter gets renamed or added.

A new Refresh schema before call toggle, in the tool's configuration panel and on by default, checks the MCP server for the tool's current schema right before each call, so the workflow keeps working even if you never refresh it manually. When disabled, the tool always uses the schema you configured, which is faster and more predictable if the server's tools rarely change. The setting is saved with the workflow and survives closing and reopening the project.

Trigger ad-hoc case tasks through the CaseApp API

In Maestro Case, a new POST /instances/{instanceId}/tasks/trigger endpoint on the v3 CaseApp API lets you manually start an ad-hoc task on a running case instance by supplying its case-plan task name. Access requires the Cases.RunAdhocTasks permission scoped to the stage that owns the task. Task name matching is case-sensitive, and only tasks with an "adhoc" entry condition in the case plan are eligible — other names return a 404.

For more information, see CaseApp requests.

Correções de bugs

• Maestro BPMN: =js: expressions used as Data Fabric query filter values are now evaluated before the query is sent, so dynamic values resolve correctly instead of being passed through as raw expression strings. For more information, see Data Fabric operations.
• Maestro BPMN: The Get queue items activity no longer fails on Orchestrator tenants with the Strict OData API setting enabled. For more information, see Queue task activities.
• Maestro BPMN: Multi-instance elements with large marker input collections no longer fail during execution. For more information, see Markers.
• Maestro BPMN: A Studio Web debug run against an empty queue now returns a 404 (user error) instead of a 500 (system error); deployed runs are unaffected.
• Maestro Flow: Evaluation output evaluators (such as Exact Match) are now pre-selected and pre-filled with the shared expected output entered in the evaluation wizard. For more information, see Evaluations.
• Maestro Flow: The MCP server picker in the add-node panel now loads all available servers instead of stopping at the first 100. For more information, see Agent.
