## Tools

12 declared. Observed from a live `tools/list` probe.
- `find_data` — Describe the data you need in plain language (e.g. 'Apple risk factors 2023', 'is this token a honeypot', 'is this email deliverable', 'read this page'). Search
- `pricing` — Every endpoint this server fronts, with its exact per-call USD price (x402, USDC on Base) and a one-line summary, read live from the route table. Free.
- `request_data` — The suggestion box: ask for data we don't have (a pre-2015 filing, an uncovered ticker, an unsupported chain, a whole dataset). Requests feed the nightly ingest
- `gas_price` — Bid-ready EIP-1559 fees (slow/standard/fast maxFeePerGas + maxPriorityFeePerGas, tx-ready wei) for one chain, read live from public RPCs. Pass tx_type to get th
- `gas_compare` — Rank every supported chain by all-in USD transaction cost — the 'where should I send this' routing decision, with the OP-stack L1 data fee included. Paid: call 
- `spot_price` — Live Chainlink on-chain spot price for an asset (latestRoundData, with round metadata). Pass `to` as well to cross-convert two assets via their USD feeds, with 
- `token_safety` — Heuristic token safety check: follows the proxy and scans the bytecode that actually runs, plus ownership and transfer restrictions. Returns a verdict with per-
- `address_screen` — Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent al
- `swap_quote` — Indicative UniswapV2 swap quote from live on-chain reserves: amount out, execution price, and price impact — what the trade will actually cost before you sign i
- `ens_resolve` — Resolve an ENS name to an address, or an address to its forward-verified primary name — direction is detected from the input. view='profile' returns the full id
- `chain_info` — Canonical record for an EVM chain — name, native currency, explorers, liveness-scored public RPCs. view='rpcs' returns only the ranked, eth_chainId-probed RPC l
- `nft_scam_check` — Deterministic scam checklist with a verdict and evidence (spam flags, copymint collisions, holder concentration). Pass a collection contract to check the collec

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"sausage-onchain\": {\n      \"type\": \"http\",\n      \"url\": \"https://x402.professorsausages.com/mcp/onchain\"\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
