onchain-safety-mcp

MCP (Model Context Protocol) server that gives any AI agent on-chain token-safety tools for PulseChain, Monad, Base, and BSC — including PulseChain, which the major token-safety APIs (GoPlus, Honeypot.is) don't support at all (verified June 2026). If your agent touches PulseChain, this is the safety check.

It is a thin stdio client over the hosted API at onchain.wick.pics (engine wick-safe/0.3). Every check is deterministic on-chain analysis — no LLM in the verdict path, so results are fast, cheap, and reproducible: contract-risk heuristics, liquidity depth, honeypot transfer-simulation, LP-burn, ownership/renounce + privilege detection, upgradeable-proxy detection, and a wallet approval (drainer) scanner. The free tier needs no key. Informational, not financial advice.

Tools

tool

what it answers

check_token_safety({ chain, address })

Is this token a scam? Verdict (SAFE … LIKELY_RUG), 0–100 score, evidence checks.

fresh_rug_radar()

What just launched, and is it safe? Last 20 freshly-created pools, safety-scored at creation.

exit_safety({ chain, token, sizeUsd, maxSlippage? })

Could I sell $X of this at acceptable slippage? Size-aware price impact + safety verdict.

check_ownership({ chain, address })

Is ownership renounced / upgradeable, and what can an active owner still do (mint, blacklist, pause, tax)?

safe_to_interact({ chain, address })

One call → SAFE_TO_INTERACT / CAUTION / DO_NOT_INTERACT, bundling safety + ownership, with reasons.

wallet_approvals({ chain, owner })

A wallet's active ERC-20 approvals, flagging unlimited grants — the drainer vector.

wallet_poison_check({ chain, owner })

Address-poisoning scan: dust/look-alike transfers in a wallet's history that mimic a real counterparty to trick a paste-and-send of the wrong address.

chain: pulsechain | monad | base | bsc · token/address: 0x… contract address. Agents should call check_token_safety / exit_safety before interacting with, buying, or accepting an unknown token.

ONCHAIN_API_KEY is optional — omit it for the free rate-limited tier. A wsk_ key unlocks the paid deep tier (get one at onchain.wick.pics).

Pay-per-call for autonomous agents (x402)

The same engine is available with no signup and no key via the x402 pay-per-call protocol — agents pay USDC on Base per request. Machine-readable index of every paid route (token-safety, fresh-rug radar, exit-safety):
