Tools & Capabilities Breakdown

Gia MCP Server Tools (57)

classify_decision

Classify an AI agent decision using the MAI Framework (Mandatory/Advisory/Informational). Returns classification level, confidence score, gate requirements, and rationale.

get_gate_status

Check resolution of a MANDATORY gate. Call this after classify_decision returns gateStatus: PENDING. Polls for up to 60 seconds — re-call if still PENDING. Do not proceed with the classified action until this returns APPROVED.

evaluate_threshold

Compute the Storey Threshold — escalation rate (gates required / total operations). Returns current rate, status, and recommendations. Healthy band 10-18% is a design heuristic, not empirically validated.

score_governance

Compute weighted governance score from caller-provided Integrity, Accuracy, and Compliance values (0-1). Returns weighted composite and pass/fail against configured thresholds. Scores are caller-assessed — this tool applies weights and thresholds, not independent evaluation.
