## Trust

- hygiene: 80
- liveness: 100
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website +reachable +uptime-100% +updated-7d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: check_token (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gas_now (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_x402_payability (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 695 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 3 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 695 tokens to load them all
- tool set hash: c145f706dadd0cb52f679ab3d4f67be3
- tools last changed: 2026-10-13T14:06:00.503Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.appin60.contractlens-api/contractlens.svg)](https://protogrid.dev/servers/com.appin60.contractlens-api/contractlens)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `check_x402_payability` added
  - For x402 sellers: can a real buyer actually pay this endpoint? Sends one payment signed by a fresh unfunded key through the endpoint's server and facilitator. Payable endpoints fail only on balance; anything else is reported with the exact reason (schema, description over 500 chars, EIP-712 domain, price over the $1 default client cap, paywall not enforcing).
- 2026-10-13 `address_info` added
  - What is this address? EOA, EIP-7702 delegated EOA, Safe multisig (threshold, owners), timelock, ERC-20 token, proxy or contract, with native balance. Use before sending funds to or trusting an address.
- 2026-10-13 `gas_now` added
  - Live EIP-1559 gas for a chain: base fee, slow/standard/fast tips, maxFeePerGas values and the cost of common actions. Chains: 1, 8453, 42161, 10, 137, 56.

## Tools (5)

- `address_info`: What is this address? EOA, EIP-7702 delegated EOA, Safe multisig (threshold, owners), timelock, ERC-20 token, proxy or contract, with native balance. Use before sending funds to or trusting an address.
- `check_token`: Fast (1-3 s) risk verdict for an ERC-20 token before buying it: LOW/MEDIUM/HIGH with reasons. Who controls it (renounced, single key, Safe multisig, timelock), upgradeable proxy, admin powers in the bytecode (mint, blacklist, pause, adjustable tax, trading switch), source verification, DEX liquidity and pair age. Chains: 1 Ethereum, 8453 Base, 42161 Arbitrum, 10 Optimism, 137 Polygon, 56 BNB.

- `scan_contract`: Security scan of a verified EVM smart contract: who controls it now (owner / proxy admin: renounced, single-key EOA or Safe multisig), every owner/role-gated function (mint, pause, blacklist, upgrade, fees), proxy status, and Slither static-analysis findings ranked by impact. Use before approving, depositing into or buying a token. Chains: 1 Ethereum, 8453 Base, 42161 Arbitrum, 10 Optimism, 137 Polygon, 56 BNB.
