What data it sees

Do you need an account

No: the server works without sign-in

Verify AI decisions against sealed governance artifacts in under 5ms. Generate .nomos artifacts from policy documents with cryptographic sealing. Detect contradictions between written policy and observed behavior. Built for agentic systems that need tamper-proof, auditable decision logic.

How to connect

How to connect NOMOS Governance to Claude

Raw names from tools/list. Only developers need these.

verify_decisionCheck whether an AI decision is allowed, denied, or needs escalation according to a sealed NOMOS governance artifact. Returns verdict (allow/deny/escalate), confidence score (0-1), audit hash for the decision log, and the specific rule that fired. Evaluates in under 5ms. Use pub_lending_v1, pub_refund_v1, pub_fraud_v1, pub_hr_leave_v1, or pub_kyc_v1 as artifact_id for public demos.
generate_governanceConvert one or more policy documents into a sealed NOMOS governance artifact (.nomos). Extracts executable rules, detects contradictions, computes an Autonomy Readiness Index (ARI) score (0-1), and cryptographically seals the result. Returns an artifact_id you can use with verify_decision immediately.
detect_contradictionsAnalyze policy documents to detect contradictions, hidden rules, and gaps between declared policy and observed behavior. Stateless — no artifact created. Returns threshold_conflicts, ghost_terms, role_conflicts, rule_collisions, and layer_divergences.
