Expand description

JSON-RPC message type (union of request, response, notification)

MCP 2025-06-18 Compliance Note: Batch variants exist only for defensive deserialization and are NOT supported per MCP specification (PR #416 removed batch support). They will return errors if encountered.

Variants§

Request(JsonRpcRequest)

Request message (MCP-compliant)

Response(JsonRpcResponse)

Response message (MCP-compliant)

Notification(JsonRpcNotification)

Notification message (MCP-compliant)

RequestBatch(JsonRpcBatch<JsonRpcRequest>)

👎Deprecated since 2.2.3: Batching removed from MCP spec

Batch of messages (NOT SUPPORTED - defensive deserialization only)

Deprecated: MCP 2025-06-18 removed batch support. This variant exists only to return proper errors if batches are received.

ResponseBatch(JsonRpcBatch<JsonRpcResponse>)

👎Deprecated since 2.2.3: Batching removed from MCP spec

Batch of responses (NOT SUPPORTED - defensive deserialization only)

Deprecated: MCP 2025-06-18 removed batch support. This variant exists only to return proper errors if batches are received.

MessageBatch(JsonRpcBatch<JsonRpcMessage>)

👎Deprecated since 2.2.3: Batching removed from MCP spec

Mixed batch (NOT SUPPORTED - defensive deserialization only)

Deprecated: MCP 2025-06-18 removed batch support. This variant exists only to return proper errors if batches are received.
