Open-source tool CATT v0.2.1 enables developers to test MCP servers and APIs against simulated mainstream AI assistants (e.g., Muse/Instinct) within CI pipelines. Using a surrogate emulation mechanism with confidence-labeled behaviors, it addresses the challenge of black-box assistant testing while clarifying that passing tests do not certify official compatibility.

    • Enables automated agent behavior testing for MCP servers, websites, and HTTP APIs within CI workflows
    • Introduces Muse and Instinct as emulation targets with four-tier transparency labels (documented/unofficial/assumed/unknown) for behavioral assumptions
    • Positioned as a 'test host' rather than a full implementation replica, explicitly stating that passing tests does not certify official assistant compatibility
