Handler for an MCP tool.

Required Methods

fn call<'life0, 'life1, 'async_trait>( &'life0 self, arguments: Option<Value>, auth_token: Option<&'life1 str>, ctx: McpRequestContext, ) -> Pin<Box<dyn Future<Output = Result<ToolsCallResult, AppError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Execute the tool.

auth_token is the token string (if provided by the client). Tools can use this for secondary checks (e.g., haptic permission) after the server validates token well-formedness/expiry.
