Automated Reasoning SMT solver, not an LLM. ZK proofs included. ``` Scanned 2026-10-21T19:28:56.011Z over streamable-http. **14 tools: 13 change things and 1 only read.** | Group | Class | Tools | Claude Code | | --- | --- | --- | --- | | Deletes or cancels | destructive | 0 | deny | | Can't be undone | irreversible | 0 | ask | | Changes things | write | 13 | ask | | Only reads | read | 1 | allow | ## Findings No check matched anything in these tool definitions. ## Changes things (13) Creates or changes something that can be changed back. Claude Code: ask. ### `check_action` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_paid` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_logic` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_relevance` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_account` - The name "create_account" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_card` - The name "create_account_card" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `make_rules` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_session` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_check` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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_tests` - The name "run_tests" says "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_up` - The description's first verb is "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_card` - The description's first verb is "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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_proof` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (1) Looks things up and changes nothing. Claude Code: allow. ### `get_scenarios` - The name "get_scenarios" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `icme-preflight`: ```json { "permissions": { "allow": [ "mcp__icme-preflight__get_scenarios" ], "ask": [ "mcp__icme-preflight__check_logic", "mcp__icme-preflight__check_relevance", "mcp__icme-preflight__make_rules", "mcp__icme-preflight__check_action", "mcp__icme-preflight__check_action_paid", "mcp__icme-preflight__quick_check", "mcp__icme-preflight__verify_proof", "mcp__icme-preflight__run_tests", "mcp__icme-preflight__create_account", "mcp__icme-preflight__create_account_card", "mcp__icme-preflight__top_up", "mcp__icme-preflight__top_up_card", "mcp__icme-preflight__poll_session" ], "deny": [] } } ```
