# `GenMCP.MCP.V2607.CancelledNotification`
[🔗](https://github.com/lud/gen_mcp/blob/main/lib/gen_mcp/mcp/v2607/entities.ex#L510)

Struct and module-based JSON schema generated from
[modelcontextprotocol.io JSON schema](https://github.com/modelcontextprotocol/modelcontextprotocol/tree/main/schema/2026-07-28/schema.json).

This notification is sent by the client to indicate that it is
cancelling a request it previously issued.

On stdio, the server also sends this notification, solely to terminate
a {@link SubscriptionsListenRequestsubscriptions/listen} stream: it
references the ID of the `subscriptions/listen` request that opened
the stream. Servers MUST NOT use this notification to cancel any other
request.

The request SHOULD still be in-flight, but due to communication
latency, it is always possible that this notification MAY arrive after
the request has already finished.

This notification indicates that the result will be unused, so any
associated processing SHOULD cease.

# `t`

# `json_schema`

# `method`
