No longer in the registry. The MCP registry stopped listing this server as of 31 Aug 2026. This page stays available because the measurement was real, but the server is excluded from search, rankings, and Vouch’s corpus counts. A published behaviour score is never recomputed or removed — it reflects what was measured while the server was listed.
Owner verification
Not yet verified. Verifying proves you control this server and is free, permanently — it never changes a published score.
Start verification →Tools
- check_actionshallow
Enforce a guardrail: verify an agent action against a compiled policy using formal verification. An SMT solver — not an LLM — determines whether the action satisfies every rule. Returns SAT (allowed) or UNSAT (blocked) with extracted values and a cryptographic ZK proof that the check was performed correctly. Cannot be jailbroken. 1 credit ($0.01). Requires api_key. Tip: end the action with an explicit claim like 'I assert this complies with the policy' for best extraction.
- check_action_paidshallow
Same formal verification as check_action, but pay per call with x402 ($0.10 USDC on Base) instead of using credits. No API key or account needed — any agent with a wallet can verify actions on the fly. Returns SAT (allowed) or UNSAT (blocked) with extracted values and optional ZK proof.
- check_logicshallow
Catch contradictions in reasoning before acting on it. FREE — no account needed. Extracts quantitative and logical claims from any plan, calculation, or chain of thought, then uses a Z3 SAT solver to mathematically prove whether they contradict each other. This is formal verification, not an LLM second-guessing itself. Returns CONSISTENT, CONTRADICTION, or UNKNOWN with the extracted claims.
- check_relevanceshallow
Free relevance screen — checks whether an action touches any of your policy variables before running a paid check. Returns a relevance score and which variables matched. If should_check is true, run check_action. If false, the action is unrelated to your policy — skip the paid check. No credits charged. Requires api_key.
- create_accountshallow
Create an ICME Preflight account with x402 USDC payment ($5.00 on Base). Returns an API key and 325 starting credits immediately. Save the api_key — it is shown only once. Use create_account_card instead if paying by credit card.
- create_account_cardshallow
Create an ICME Preflight account with a credit card ($5.00 via Stripe). Returns a checkout_url — open it in a browser to pay. After payment completes, call poll_session with the session_id to retrieve your API key.
- get_scenariosshallow
Review auto-generated test scenarios for a compiled policy. Shows example actions that should pass and fail, so you can verify the policy behaves as intended before deploying it. Requires api_key.
- make_rulesshallow
Turn a plain-English policy into a jailbreak-proof guardrail. Write rules the way you would explain them to a colleague — ICME compiles them into formal logic (SMT-LIB) that a mathematical solver enforces. No prompt engineering. No LLM judges. The solver either proves an action complies or it doesn't. Returns a policy_id and test scenarios for review. Costs 300 credits. Requires api_key.
- poll_sessionshallow
Check the status of a Stripe card payment. Returns pending or complete. On completion after signup, returns the api_key. Call this after create_account_card or top_up_card once the user has paid.
- quick_checkshallow
Fast yes/no guardrail verdict — returns only ALLOWED or BLOCKED with no proof details. Use when you need a lightweight gate and don't need the full SAT/UNSAT report or ZK proof. Same formal verification under the hood, just a minimal response. 1 credit. Requires api_key.
- run_testsshallow
Run saved test cases against a policy to confirm it blocks what it should block and allows what it should allow. Run this after make_rules and before using the policy in production. Requires api_key.
- top_upshallow
Add 500 credits to your account via x402 USDC payment ($5.00 on Base). Use top_up_card instead for credit card payment with volume discounts. Requires api_key.
- top_up_cardshallow
Add credits via credit card with volume bonuses. Returns a checkout_url. Tiers: $5 = 500 credits, $10 = 1,050 (+5%), $25 = 2,750 (+10%), $50 = 5,750 (+15%), $100 = 12,000 (+20%). Credits never expire. Requires api_key.
- verify_proofshallow
Independently verify a ZK proof from a prior check_action call. Confirms the guardrail check was performed correctly without re-running it — any third party or monitoring agent can verify in under one second. No additional cost. Wait a few minutes after the check for the proof to be generated. Single-use per proof.
