Is approval-revoke-mcp live?

Yes — it answered the hub's last check (checked 2h ago). It answered 99% of checks over the last 30 days.

Is approval-revoke-mcp free to use?

No — it charges per call, from 0.1 USDC, quoted in its own 402 answers.

What tools does approval-revoke-mcp have?

3 tools: approvals_risk, spender_reputation, list_approvals.

Is approval-revoke-mcp safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• list_approvals reads 0.1 USDC paid 11h ago

  List active EVM token approvals for a wallet across one or more chains. Scans recent ERC-20 Approval and ERC-721/1155 ApprovalForAll events via eth_getLogs, then confirms each (token, spender) pair is still active by reading allowance() / isApprovedForAll() on-chain. Returns per-chain summary (total, unlimited count, ERC-20 vs ERC-721 split) plus a flat list of active approvals with spender labels where known. Multichain (ethereum/base/arbitrum/optimism/polygon). Costs $0.10 USDC on Base via x402.

• approvals_risk reads unknown never probed

  Composite 0–100 approval-risk score for an EVM wallet.

Returns risk_score, risk_band (clean/low/medium/high/critical), top-10 risk-ranked approvals, and human-readable reasons array. Multichain. Costs $0.20 USDC on Base via x402.

• spender_reputation reads unknown never probed

  Single-spender reputation lookup. Checks against bundled known-spenders dictionary (~30 major routers/aggregators/marketplaces) + known-malicious dictionary (drainer families), and reads on-chain code via eth_getCode to detect EOA. Returns label, category, is_known_malicious, is_eoa, and recommendation (trusted / caution / do-not-approve). EOAs receiving unlimited approvals are highly suspicious. Costs $0.05 USDC on Base via x402.
