Input Schema

Request message for AgentService.DeleteTool.

DeleteToolRequest

JSON representation 
{
  "name": string,
  "force": boolean,
  "etag": string
}
Fields
name

string

Required. The resource name of the tool to delete.
force

boolean

Optional. Indicates whether to forcefully delete the tool, even if it is still referenced by agents/examples.

  • If force = false, the deletion will fail if any agents still reference the tool.
  • If force = true, all existing references from agents will be removed and the tool will be deleted.
etag

string

Optional. The current etag of the tool. If an etag is not provided, the deletion will overwrite any concurrent changes. If an etag is provided and does not match the current etag of the tool, deletion will be blocked and an ABORTED error will be returned.

Output Schema

A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance:

service Foo {
  rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
}

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: ❌
