  "markdown": "# FabTally Safe — MCP server\n\nRead-only crypto **safety + \"what am I signing\"** verification for AI agents and\nwallets. Fronts the FabTally Safe HTTP API (https://safe.fabtally.com).\n\n- **Read-only.** Never holds, moves, signs for, or broadcasts funds. No private\n  key. Outputs are descriptive facts from public sources — **not financial advice**.\n- **8 tools**: 4 free teasers + 4 paid (x402, USDC on Base).\n\n## Tools\n\n| Tool | Tier | What it does |\n|------|------|--------------|\n| `token_safety` | paid $0.02 | Multi-chain token honeypot/rug check — aggregates GoPlus + honeypot.is into a 0-100 risk score with explainable reasons. |\n| `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). |\n| `approvals` | paid $0.01 | Wallet approval-risk scan ranked by exposure + address-poisoning \"revoke bait\" detection + the revoke calldata you execute yourself. |\n| `simulate` | paid $0.02 | Keyless pre-sign transaction analysis: eth_call revert check + static delta prediction + risk flags. |\n| `token_safety_free` · `decode_signature_free` · `approvals_free` · `simulate_free` | free | Real teaser results, no wallet. |\n\nChains: ethereum, base, bsc, polygon, arbitrum, optimism (honeypot.is signals on\nethereum/base/bsc).\n\n## Payment\n\nPaid tools use **x402** (USDC on Base, `eip155:8453`). Call a paid tool with no\n`x_payment` to receive the decoded 402 challenge (price, network, asset, payTo);\nbuild an x402 authorization and call again with the token in `x_payment`. Humans\ncan instead prepay by card and use an `X-FabTally-Key` credit header on the HTTP API.\n\n## Transports\n\n- **stdio** (default): `node index.js` — for Claude Desktop and local MCP clients.\n- **streamable-http**: `MCP_HTTP_PORT=8113 node http.js` — hosted at\n  `https://safe.fabtally.com/mcp`.\n\n## Config\n\n- `FABTALLY_SAFE_BASE` — API base (default `https://safe.fabtally.com`).\n\nOperator: Sunstone Soft · https://fabtally.com · Not financial advice · read-only.\n",
