Compiler Compatibility

MinGW UCRT64 GCC and MinGW CLANG64 Clang are tracked as provisional, best-effort compiler compatibility evidence. These targets are not release-supported. The compiler-compat workflow runs them with continue-on-error: true while they remain provisional.

Quick Start

find_package(cxxmcp CONFIG REQUIRED)
target_link_libraries(my_server PRIVATE cxxmcp::server)

#include <cxxmcp/peer.hpp>
#include <cxxmcp/run.hpp>

int main() {
    return mcp::ServerPeer::builder()
        .name("demo-server")
        .version("1.0.0")
        .stdio()
        .tool<mcp::protocol::Json, mcp::protocol::Json>("echo",
            [](const mcp::protocol::Json& input) {
                return mcp::protocol::Json{{"echo", input}};
            })
        .run();
}

// Client side
#include <cxxmcp/peer.hpp>
#include <cxxmcp/run.hpp>

int main() {
    return mcp::ClientPeer::builder()
        .streamable_http("http://127.0.0.1:3000/mcp")
        .run([](auto& svc) {
            svc.peer().initialize();
            svc.peer().list_all_tools();
            svc.peer().call_tool("echo",
                                 mcp::protocol::Json{{"value", "hello"}});
        });
}

Examples

In-tree examples cover server/client peers, auth, tasks, elicitation, and transport adapters. Run them with:

cmake --preset examples && cmake --build --preset examples && ctest --preset examples

See examples.md for the full list. The separate cxxmcp-examples repository exercises the SDK through an external CMake project with advanced scenarios.
