Tool handler trait - the core abstraction for tool execution

Required Methods

fn call(&self, args: Value) -> BoxFuture<'_, Result<CallToolResult>>

Execute the tool with the given arguments

fn input_schema(&self) -> Value

Get the tool’s input schema

Provided Methods

fn call_with_context( &self, _ctx: RequestContext, args: Value, ) -> BoxFuture<'_, Result<CallToolResult>>

Execute the tool with request context for progress/cancellation support

The default implementation ignores the context and calls call. Override this to receive progress/cancellation context.

fn uses_context(&self) -> bool

Returns true if this handler uses context (for optimization)
