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

ToolTierWhat it does
token_safetypaid $0.02Multi-chain token honeypot/rug check — aggregates GoPlus + honeypot.is into a 0-100 risk score with explainable reasons.
decode_signaturepaid $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).
approvalspaid $0.01Wallet approval-risk scan ranked by exposure + address-poisoning "revoke bait" detection + the revoke calldata you execute yourself.
simulatepaid $0.02Keyless pre-sign transaction analysis: eth_call revert check + static delta prediction + risk flags.
token_safety_free · decode_signature_free · approvals_free · simulate_freefreeReal 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.

Config

  • FABTALLY_SAFE_BASE — API base (default https://safe.fabtally.com).
