Struct ToolAnnotations 

pub struct ToolAnnotations {
    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>,
}

A tool’s hints.

Every field here is a hint, not a guarantee: the schema says so directly, and says a client must never make a tool-use decision from an untrusted server’s hints. Modelled because a registry that drops them loses data the specification defines.

Carrying hints does not raise a primitive’s required features, and that is deliberate — see Primitive::meta. A peer on an older revision ignores hints it does not know and calls the tool all the same, so gating visibility on them would hide a working tool for no gain.

Fields

title: Option<String>

title.

read_only_hint: Option<bool>

readOnlyHint. Absent means unknown, not false.

destructive_hint: Option<bool>

destructiveHint.

idempotent_hint: Option<bool>

idempotentHint.

open_world_hint: Option<bool>

openWorldHint.
