Struct ToolCallRequest 

pub struct ToolCallRequest {
    pub name: String,
    pub arguments: Value,
    pub tool_call_id: Option<String>,
    pub progress_token: Option<Value>,
}

A tool invocation as carried on a route REQUEST frame.

Fields

name: String

The provider’s bare manifest tool name (no gateway prefix).

arguments: Value

The arguments exactly as the caller supplied them; consumers never translate them, and the provider’s manifest schema is what accepts or rejects their shape.

tool_call_id: Option<String>

The consumer’s own identifier for this call, minted by whatever dispatched it (a model runner’s WAL intent id, a gateway request id). Opaque to the daemon and to subc; unique per call on the consumer’s side, so a provider’s at-most-once fence can key on it directly instead of synthesizing an id from the call’s contents.

None is a statement about the PRODUCER, not the call: it means this consumer did not supply an id, never that the call has no identity. A reader must not collapse the two — the moment a legacy producer is on the other end, treating None as “no id exists” and synthesizing one silently reproduces exactly the failure this field exists to end. A reader that synthesizes a fallback id when this is None must record that the fallback fired (a fallback that never reports firing is indistinguishable from a working component that is quietly wrong).

progress_token: Option<Value>

An MCP progress token the consumer wants progress notifications correlated to, when the caller requested progress. Opaque here.

Implementations

impl ToolCallRequest

pub fn new(name: impl Into<String>, arguments: Value) -> Self
