Struct CallToolParams 

pub struct CallToolParams {
    pub name: String,
    pub arguments: Value,
}

Invoke a page-declared tool by name. [callTool]: method WebMCP.callTool.

An engine that implements WebMCP.callTool runs the tool and returns its result as opaque JSON — commonly a WebMCP tool-result object with a content array and an isError flag (a failing tool is reported in-band as isError: true, not as a protocol error).

Not every engine implements WebMCP.callTool. Depending on the engine’s unknown-method policy, an unimplemented call surfaces either a protocol error or an empty success result — treat an empty object as “not supported yet” and discover live tools via WebMCP.listTools. The response is returned as opaque JSON (serde_json::Value) so the client does not constrain the result shape.

Fields

name: String

The name of the tool to invoke, as reported by WebMCP.listTools.

arguments: Value

Arguments for the tool, matching its inputSchema.
