Struct ToolDef

Source

pub struct ToolDef {
    pub id: Cow<'static, str>,
    pub description: Cow<'static, str>,
    pub schema: Schema,
    pub invocation: InvocationHint,
    pub output_schema: Option<Value>,
    pub server_id: Option<String>,
}

Fields§

§id: Cow<'static, str>§description: Cow<'static, str>§schema: Schema§invocation: InvocationHint§output_schema: Option<Value>

Raw output schema from an MCP server, if present.

DO NOT convert to schemars::Schema — lossy; see #2931 critique P0-1.

§server_id: Option<String>

ID of the MCP server that registered this tool, or None for built-in tools.

This is the authoritative way to determine whether a tool originates from an MCP server — id is a sanitized, server-namespaced string with no reliable prefix to pattern-match on (see #5712).
