Remarks

A tool failure is reported by setting IsError on a successful JSON-RPC response, not by returning a protocol error. This lets the caller see what went wrong and correct itself, which a transport-level error would not allow.

Properties

Content

Gets the content blocks returned to the caller.

IsError

Gets or sets a value indicating whether the call failed. When true, the content should explain what happened and how to proceed.

StructuredContentJson

Gets or sets a JSON object carrying the machine-readable form of the result, mirroring the tool's output schema. Supplied alongside the textual content, never instead of it.

Methods

Add(McpContent)

Appends a content block.

FromError(string)

Creates a failed result. The message should state what went wrong and, where possible, the corrective action, so the caller can recover without a round trip to the user.

FromText(string)

Creates a result carrying a single text block.
