Tool: cancel_workflow_invocation

Request the graceful termination of a running Dataform workflow invocation.

This tool sends a cancellation signal to the running workflow. However, any individual BigQuery jobs, table creations, or assertions that have already completed as part of this workflow will not be rolled back.

The name parameter value must be in the format projects/{project_id}/locations/{location}/repositories/{repository}/workflowInvocations/{workflow_invocation}.

The following code sample shows how to use curl to call the cancel_workflow_invocation MCP tool.

Tool Annotations

Tool annotations are sent to MCP clients to describe the basic risk of a given tool. Most clients treat these hints as untrusted, but they can be used to decide when a confirmation prompt might be sent to a user.

Along with the title string, the following boolean hints are defined as follows:

  • readOnlyHint: If true, the tool doesn't modify its environment. Default: false.
  • destructiveHint: If true, then the tool can perform destructive actions. If false, then the tool can only perform additive actions. Default: true.
  • idempotentHint: If true, then calling the tool repeatedly with the same arguments will have no additional effect on its environment. Default: false.
  • openWorldHint: If true, then the tool can interact with an 'open world' of external entities. If false, then the tool can only interact with internal entities. For example, a web search tool would be open world, while a memory tool would not be open world.

Destructive Hint: ❌ | Idempotent Hint: ❌ | Read Only Hint: ❌ | Open World Hint: ❌
