Struct McpToolAnnotations 

#[non_exhaustive]
pub struct McpToolAnnotations {
    pub title: Option<String>,
    pub read_only_hint: Option<bool>,
    pub destructive_hint: Option<bool>,
    pub idempotent_hint: Option<bool>,
    pub open_world_hint: Option<bool>,
}

Additional properties describing a Tool to clients.

NOTE: all properties in ToolAnnotations are hints. They are not guaranteed to provide a faithful description of tool behavior (including descriptive properties like title).

Clients should never make tool use decisions based on ToolAnnotations received from untrusted servers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

title: Option<String>

A human-readable title for the tool.

read_only_hint: Option<bool>

If true, the tool does not modify its environment.

Default: false

destructive_hint: Option<bool>

If true, the tool may perform destructive updates to its environment. If false, the tool performs only additive updates.

(This property is meaningful only when readOnlyHint == false)

Default: true A human-readable description of the tool’s purpose.

idempotent_hint: Option<bool>

If true, calling the tool repeatedly with the same arguments will have no additional effect on the its environment.

(This property is meaningful only when readOnlyHint == false)

Default: false.

open_world_hint: Option<bool>

If true, this tool may interact with an “open world” of external entities. If false, the tool’s domain of interaction is closed. For example, the world of a web search tool is open, whereas that of a memory tool is not.

Default: true
