Properties

Meta

Gets or sets metadata reserved by MCP for protocol-level metadata.

[JsonPropertyName("_meta")]
public JsonObject? Meta { get; set; }

Property Value

JsonObject

Remarks

Implementations must not make assumptions about its contents.

ResultType

Gets or sets the type of the result, which allows the client to determine how to parse the result object.

[JsonPropertyName("resultType")]
public string? ResultType { get; set; }

Property Value

string

Defaults to null, which is equivalent to "complete".

Remarks

When absent or set to "complete", the result is a normal completed response. When set to "input_required", the result is an InputRequiredResult indicating that additional input is needed before the request can be completed. When set to "task", the result is a CreateTaskResult indicating that the server has created a long-running task in lieu of returning the result directly.
