Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@onchain-safety-mcpCheck token safety for 0x123 on base"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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 |
| Is this token a scam? Verdict ( |
| What just launched, and is it safe? Last 20 freshly-created pools, safety-scored at creation. |
| Could I sell $X of this at acceptable slippage? Size-aware price impact + safety verdict. |
| Is ownership renounced / upgradeable, and what can an active owner still do (mint, blacklist, pause, tax)? |
| One call → SAFE_TO_INTERACT / CAUTION / DO_NOT_INTERACT, bundling safety + ownership, with reasons. |
| A wallet's active ERC-20 approvals, flagging unlimited grants — the drainer vector. |
| 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.
