# @celorodrigues/token-safety-mcp

MCP server for Base L2 token safety: bytecode scans, swap simulations, approval and liquidity risk, and the live new-pool channel — six paid x402 surfaces plus x402 infrastructure tools, with payment handled server-side.

## Tools

13 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `x402_health` — Check that the x402 Value API is live and read its advertised payment terms (network, chainId, asset, payTo, schemes).
- `x402_pricing` — Read per-route pricing for the Value API (USDC amounts per route, the six surfaces, the free trial).
- `x402_conformance` — Audit ANY x402 service: fetches its 402 challenge and returns a pass/fail conformance verdict (scheme, network, chainId, asset, payTo, amount).
- `verify_payment` — Verify an on-chain ERC-20/USDC transfer on Base (free). Confirms the tx is real and confirmed, paid the right recipient, and met a minimum amount.
- `x402_index` — Read the live x402 service leaderboard (objectively scored by the conformance engine).
- `x402_submit` — Free self-submission: add your own x402 service to the public leaderboard. Returns the queued entry.
- `x402_paid_uuid` — PAID call (0.001 USDC on Base) that returns a settled UUID, proving the whole x402 loop end to end. Settled by this server on your behalf when a payer is config
- `token_scan` — Bytecode security scan of a Base token contract (PAID, 0.001 USDC). Reports honeypot opcodes, mint/blacklist/pause/tax capabilities, a risk score and a verdict.
- `tx_simulate` — Read-only buy/sell simulation of a Base token through the Uniswap V2 WETH pool (PAID, 0.01 USDC). Returns reverts, the measured transfer tax and a honeypot verd
- `approval_risk` — Read-only audit of the ERC-20 approvals an owner granted for a token (PAID, 0.01 USDC): spender, allowance, contract vs EOA, verified flag, drainable amount and
- `liquidity_risk` — One-block liquidity audit of a Base token (PAID, 0.01 USDC): Uniswap V3 / Aerodrome pools, USD needed to move the price 1/2/5/10%, concentration, LP burn eviden
- `sentinel_latest` — Newest liquidity pools created on Base (Uniswap v3/v4, Aerodrome) with a bytecode risk score per new token (PAID, 0.001 USDC). Filters are optional.
- `sentinel_stream` — Subscribe to the live Base pool channel (/v2/sentinel/stream, SSE, 0.01 USDC). Unlike the other five this is a CONTINUOUS channel, not a discrete RPC action: th

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"token-safety\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@celorodrigues/token-safety-mcp\"\n      ],\n      \"env\": {\n        \"AUTOMATON_MCP_PAYER_KEY\": \"<YOUR_AUTOMATON_MCP_PAYER_KEY>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `AUTOMATON_MCP_PAYER_KEY` — Automaton Mcp Payer Key (optional)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 1 credential (0 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Moderate blast radius — runs locally and hosted; holds an api key.
- Floor 25, ceiling 25 (tier: moderate)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
