What can you do with FabTally Safe?

FabTally Safe — MCP server

Read-only crypto safety + "what am I signing" verification for AI agents and wallets. Fronts the FabTally Safe HTTP API (https://safe.fabtally.com).

Read-only. Never holds, moves, signs for, or broadcasts funds. No private key. Outputs are descriptive facts from public sources — not financial advice.
8 tools: 4 free teasers + 4 paid (x402, USDC on Base).

Tools

Tool	Tier	What it does
`token_safety`	paid $0.02	Multi-chain token honeypot/rug check — aggregates GoPlus + honeypot.is into a 0-100 risk score with explainable reasons.
`decode_signature`	paid $0.01	"What am I signing" — decode EIP-712 / Permit / Permit2 / Seaport typed-data into plain English + risk flags (unlimited approval, malicious spender, expiry, NFT-drain).
`approvals`	paid $0.01	Wallet approval-risk scan ranked by exposure + address-poisoning "revoke bait" detection + the revoke calldata you execute yourself.
`simulate`	paid $0.02	Keyless pre-sign transaction analysis: eth_call revert check + static delta prediction + risk flags.
`token_safety_free` · `decode_signature_free` · `approvals_free` · `simulate_free`	free	Real teaser results, no wallet.

Chains: ethereum, base, bsc, polygon, arbitrum, optimism (honeypot.is signals on ethereum/base/bsc).

Payment

Paid tools use x402 (USDC on Base, eip155:8453). Call a paid tool with no x_payment to receive the decoded 402 challenge (price, network, asset, payTo); build an x402 authorization and call again with the token in x_payment. Humans can instead prepay by card and use an X-FabTally-Key credit header on the HTTP API.

Transports

stdio (default): node index.js — for Claude Desktop and local MCP clients.
streamable-http: MCP_HTTP_PORT=8113 node http.js — hosted at https://safe.fabtally.com/mcp.
