// Note: Full MCP handler tests would require exposing the mcp module publicly
// For now, we test the protocol serialization above
// Integration tests would be run against the actual MCP server binary

// Note: Tests import from the binary crate via the test harness
// The mcp module and config are not public in the binary, so we test via the public API
