  "markdown": "# FabTally Guard — MCP server\n\nDe-risk-a-dollar verification checks an AI agent runs **before** a costly action.\nFronts the Guard HTTP API at **https://guard.fabtally.com**. Holds no private key.\n\n## Tools (all paid; a call with no payment returns the decoded x402 402 challenge)\n\n| Tool | Price | What it does |\n|------|-------|--------------|\n| `deps_check` | $0.003 | Vet a package before installing — OSV.dev CVEs, typosquat similarity, deprecation/yank, SPDX license, age/download signals + a plain-English risk verdict. Args: `ecosystem` (npm\\|pypi\\|crates), `name`, `version?`. |\n| `x402_preflight` | $0.002 | Verify another x402 endpoint before paying it — valid x402 v2 402 challenge? price/asset/network/payTo consistent with its `/.well-known/x402`? TLS/reachability/openapi? + the parsed price. Args: `url`. |\n| `json_repair` | $0.002 | Coerce near-miss LLM JSON to a JSON-Schema-conformant object (fences/commas/quotes/keys/literals/brackets, then type-coerce, defaults, drop extras) — or precise per-field errors. Args: `json` (string), `schema`. |\n| `url_read` | $0.004 | Fetch a public url → clean Markdown + token estimate for RAG. Respects robots.txt, public pages only, nothing stored. Args: `url`. |\n\nEvery tool also accepts an optional `x_payment` (base64 x402 payload) that is\nforwarded as the `X-PAYMENT` header to settle the call and return the real result.\nHumans can instead prepay by card and use an `X-FabTally-Key` credit key against\nthe HTTP API.\n\n## Transports\n\n- **stdio** (portable): `npx fabtally-guard-mcp` (bin: `fabtally-guard-mcp`)\n- **streamable-http** (hosted): `https://guard.fabtally.com/mcp`\n\nConfig: `FABTALLY_GUARD_BASE` (default `https://guard.fabtally.com`).\n\nRead-only, keyless, stateless, descriptive. Operated by Sunstone Soft\n(fabtally.com). Not a security guarantee.\n",
