Properties

TaskSupport

Gets or sets the level of task augmentation support for this tool.

[JsonPropertyName("taskSupport")]
public ToolTaskSupport? TaskSupport { get; set; }

Property Value

ToolTaskSupport?

Remarks

This property declares whether a tool supports task-augmented execution:

• Forbidden: Clients must not attempt to invoke the tool as a task. This is the default behavior.
• Optional: Clients may invoke the tool as a task or as a normal request.
• Required: Clients must invoke the tool as a task.

This is a fine-grained layer in addition to server capabilities. Even if a server's capabilities include tasks.requests.tools.call, this property controls whether each specific tool supports tasks.
