Detailed Description

template<class Params, class Result>
struct mcp::protocol::CustomRequest< Params, Result >

Generic typed MCP request for extension methods.

Template Parameters

Params	A struct with a to_json() free function.
Result	A struct with a from_json(const Json&) -> Result<T> free function.

Example:

struct MyParams { int value; };
Json my_params_to_json(const MyParams& p) { return {{"value", p.value}}; }
 
struct MyResult { int answer; };
Json my_result_to_json(const MyResult& r) {
  return {{"answer", r.answer}};
}
core::Result<MyResult> my_result_from_json(const Json& j) { ... }
 
using MyRequest = CustomRequest<MyParams, MyResult>;
constexpr auto method = MyRequest::method_name("my/extension");
