mcp-base-token-audit

ERC-20 honeypot check and swap route data — a single-purpose MCP server for AI agents. No install, no account: it runs as a remote server; this repo also has a zero-dependency stdio bridge.

Then ask your agent, for example: Before swapping 10 USDC into 0x… on Base, run token_risk; only if the risk is low, ask get_swap_route for the transaction.

Tools

Tool	Price	What it does
token_risk	3 free calls per agent, then 0.99 USDC	Reads the contract: upgradeable proxy (EIP-1967, beacon, clone), owner powers in the bytecode (mint, pause, blacklist, fee or max-tx setters, trading switch, burn from any address), owner renounced or active and owner share of supply. Risk low, medium or high with reasons.
get_swap_route	free	Best route on Base or Ethereum (KyberSwap, 0x as fallback): quote, minimum out, approval target and, with taker, the unsigned transaction your agent signs and sends itself.
buy_pack_with_card	—	Prepaid calls by card (Stripe) when the free calls are used up.

Paying

The first 3 paid calls per agent are free (identify your agent with the header X-API-Key, or set ANGEL_API_KEY for the stdio bridge). After that each call is paid per request in USDC on Base via x402 (params._meta["x402/payment"]), with a prepaid pack (bundle_token) or by card (buy_pack_with_card). The 402 answer names the exact amount and the pay-to address before anything is signed.

Angel is a technical data and risk-analysis service only: no custody, no execution or transmission of orders, no investment advice. The disclosed 0.5 % integrator fee is a technical API provisioning fee for computing the route data; the aggregator deducts it inside a swap you send yourself. Signals from on-chain code — sell restrictions that only trigger during a trade are not simulated.
