Today is the operative word: we check KushBitx AgentProof every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

preflight

preflight

Simulate one unsigned Base transaction before an agent signs it. Runs eth_call and gas estimation on current chain state, decodes the intent (ERC-20 transfer, approve, NFT setApprovalForAll), flags unlimited approvals, calldata sent to a non-contract, zero-address targets, reverts and destination risk labels such as phishing or sanctions. Returns ALLOW, WARN, BLOCK or INCOMPLETE with findings. No key or signed transaction is requested. Paid tool: 0.001 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.

quick

quick_check

Fast pre-payment sanity check for agents on Base: confirms the RPC reports Base mainnet (chain ID 8453) and that the official USDC contract has deployed code. No request body. Returns PASS or FAIL with both checks and a timestamp. It is not a token-risk report, transaction simulation or payment proof. Paid tool: 0.001 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.

spendguard

spendguard_evaluate

Free. Check a proposed Base USDC payment against a spending policy you supply (per-transaction limit, daily budget, human-approval threshold, allowed recipients) before money moves. Returns APPROVE, HUMAN_APPROVAL or BLOCK with findings. Advisory only: it never signs, holds keys or moves funds.

token

token_risk

Token-risk report for one Base ERC-20 contract. Checks whether the token can be sold (honeypot simulation), buy/sell/transfer tax, owner privileges (mint, pause, blacklist, balance changes, proxy upgrades), holder concentration and DEX liquidity. Returns ALLOW, WARN, BLOCK or INCOMPLETE with scored findings and per-check coverage. INCOMPLETE means required evidence was unavailable, never zero risk. Read-only: never signs or trades. Paid tool: 0.001 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.

verify

verify_payment

Verify one Base USDC payment onchain before an agent releases goods or credit. Reads the transaction receipt and checks the official USDC Transfer logs against the expected recipient, amount and optional sender. Returns VERIFIED, MISMATCH, FAILED or PENDING_OR_NOT_FOUND with block number, confirmations, the matching transfer and a Basescan link. Read-only: never moves funds. Paid tool: 0.00288 USDC per call on Base via x402 (exact scheme). An unpaid call returns the payment requirement and charges nothing.

KushBitx AgentProof — questions

Answers built from our own checks of this server.

What can KushBitx AgentProof do?

It exposes 5 tools, read directly from the server on our last check. Among them: preflight, quick_check, spendguard_evaluate, token_risk, verify_payment. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is KushBitx AgentProof working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 183 ms. The bar chart above shows every period we have measured.

How do I connect KushBitx AgentProof?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does KushBitx AgentProof need an API key?

No. KushBitx AgentProof completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is KushBitx AgentProof?

It answers our handshake in 183 ms on average, which is faster than 82% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
