## MCP tools (15)

### `token_scan` (~77 tokens)

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. Read-only: no transaction is sent.

Input parameters:

- `address` (string, required): 0x-prefixed 40-hex address

### `tx_simulate` (~125 tokens)

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 verdict. No transaction is sent.

Input parameters:

- `amount` (string, required): ETH for a buy, token units for a sell (positive decimal string)
- `side` (string, required): Trade direction being simulated
- `token` (string, required): 0x-prefixed 40-hex address
- `wallet` (string, required): 0x-prefixed 40-hex address

### `approval_risk` (~107 tokens)

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 a drain-risk verdict.

Input parameters:

- `owner` (string, required): 0x-prefixed 40-hex address
- `spenders` (array): Extra spenders to check beyond the log window
- `token` (string, required): 0x-prefixed 40-hex address

### `liquidity_risk` (~97 tokens)

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 evidence and explicit coverage gaps.

Input parameters:

- `pair` (string): 0x-prefixed 40-hex address
- `token` (string, required): 0x-prefixed 40-hex address

### `sentinel_latest` (~130 tokens)

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.

Input parameters:

- `dex` (string): Restrict to one venue
- `limit` (integer): Max pools to return (default 50)
- `maxRisk` (number): Only pools whose risk score is at most this
- `minRisk` (number): Only pools whose risk score is at least this
- `since` (string): ISO-8601 timestamp; only pools detected after it

### `sentinel_stream` (~200 tokens)

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: this tool opens it, collects events for a bounded window and returns what arrived, saying so plainly. Reading again is another call. The server applies the same risk and venue filters as sentinel_latest to the pools it pushes; the `hello` event echoes the filter in force, and the result reports it as `filter`.

Input parameters:

- `dex` (string): Restrict to one venue
- `maxEvents` (integer): Stop after this many events (default 50)
- `maxRisk` (number): Only pools whose risk score is at most this
- `minRisk` (number): Only pools whose risk score is at least this
- `windowSeconds` (integer): How long to hold the channel open (default 15, max 60)

### `simulate_base_transaction` (~183 tokens)

FREE, runs locally against Base Mainnet RPC. Dry-run a transaction before sending it: eth_call + eth_estimateGas at the latest block. Predicts whether it will revert and decodes the reason (Error(string), Panic(uint256) codes, custom-error selector, or node rejection such as insufficient funds). Returns { ok, willRevert, revertReason, estimatedGas, returnData }. No transaction is sent and nothing is paid.

Input parameters:

- `data` (string): Calldata as 0x-hex (default 0x for a plain ETH transfer).
- `from` (string): Optional sender address; needed for balance/allowance-dependent calls.
- `to` (string, required): Target contract or recipient address on Base (0x...).
- `value` (string): ETH value in wei, decimal or 0x-hex (default 0).

### `x402_health` (~37 tokens)

Check that the x402 Value API is live and read its advertised payment terms (network, chainId, asset, payTo, schemes).

### `x402_pricing` (~33 tokens)

Read per-route pricing for the Value API (USDC amounts per route, the six surfaces, the free trial).

### `x402_conformance` (~62 tokens)

Audit ANY x402 service: fetches its 402 challenge and returns a pass/fail conformance verdict (scheme, network, chainId, asset, payTo, amount).

Input parameters:

- `url` (string, required): Target service URL to audit (any https URL).

### `verify_payment` (~94 tokens)

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.

Input parameters:

- `minAmount` (string): Minimum in token base units (USDC has 6 decimals; 1000 = 0.001).
- `to` (string, required): Expected recipient
- `tx` (string, required): 0x transaction hash

### `x402_index` (~26 tokens)

Read the live x402 service leaderboard (objectively scored by the conformance engine).

### `x402_submit` (~43 tokens)

Free self-submission: add your own x402 service to the public leaderboard. Returns the queued entry.

Input parameters:

- `url` (string, required): Your x402 service base URL.

### `x402_paid_uuid` (~52 tokens)

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 configured.

### `security_scan` (~132 tokens)

LEGACY NAME of token_scan, kept for callers written against the previous edge MCP. Bytecode security scan of a Base token contract (PAID, 0.001 USDC): honeypot opcodes, mint/blacklist/pause/tax capabilities, risk score and verdict. The legacy `payment` argument is accepted and ignored — this server settles x402 on your behalf, so there is no tx hash to pass.

Input parameters:

- `address` (string, required): 0x-prefixed 40-hex address
- `payment` (string): Legacy argument, accepted and ignored: this server pays on your behalf.

## Common questions

### What is the Automaton Token Safety MCP server?

Automaton Token Safety is an MCP server listed in the public MCP registry as io.github.baianomarceloeduardo-jpg/automaton-token-safety-m…. Base L2 token safety for AI agents: honeypot scans, swap simulation, approval and liquidity risk. This page covers its npm package (@celorodrigues/token-safety-mcp).

### Is the Automaton Token Safety MCP server safe to use?

Automaton Token Safety scores 79 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Automaton Token Safety MCP server expose?

Automaton Token Safety exposes 15 tools: token_scan, tx_simulate, approval_risk, liquidity_risk, sentinel_latest, and 10 more. Their descriptions and schemas cost roughly 1,398 tokens of context every time the server is loaded.

### Is the Automaton Token Safety MCP server still maintained?

Automaton Token Safety is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Automaton Token Safety MCP server under?

Automaton Token Safety declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
