## Trust

- hygiene: 100
- liveness: 100
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-99% ~updated-81d-ago
- 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: decode_signature (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); simulate_free (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); token_safety (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,702 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`: no 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: 8, about 1,702 tokens to load them all
- tool set hash: 05dd577d8ebeb57bf9f4a7ec978fe33c
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.zvmzaretsky/crypto-safety.svg)](https://protogrid.dev/servers/io.github.zvmzaretsky/crypto-safety)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `approvals`: PAID $0.01 (x402, USDC on Base). Scan a wallet's ERC-20/721 approvals ranked by exposure; flags unlimited amounts, unverified/known-malicious spenders, and address-poisoning 'fake-approval revoke bait'; returns the exact revoke calldata you execute YOURSELF (never executed/broadcast by us). Without payment returns the x402 challenge; pass x_payment. Free teaser: approvals_free.
- `approvals_free`: FREE. Approval counts + top-3 riskiest spenders for {address, chain}. Real result, no wallet. Upgrade to approvals for EVERY approval ranked + revoke calldata.
- `decode_signature`: PAID $0.01 (x402, USDC on Base). Decode an off-chain EIP-712 typed-data signature (Permit / Permit2 / Seaport / generic) into plain English with risk flags: unlimited approval, unknown/known-malicious spender, never-expiring or already-expired deadlines, zero-consideration NFT-drain orders. Off-chain signatures are the top wallet-drainer vector. Pure offline decode — never signs/broadcasts. Without payment returns the x402 challenge; pass x_payment. Free teaser: decode_signature_free.
- `decode_signature_free`: FREE. Type + plain-English summary + risk level for an EIP-712 `typed_data`. Real result, no wallet. Upgrade to decode_signature for the full field-by-field decode + all risk flags + malicious-spender screening.
- `simulate`: PAID $0.02 (x402, USDC on Base). Keyless pre-sign analysis of {chain, from?, to, data, value?}: public-RPC eth_call revert check + static calldata decode predicting approval/transfer deltas + risk flags (unlimited approval, approval-for-all, reverts). Honest keyless limitation stated in the response (no full fork trace). Without payment returns the x402 challenge; pass x_payment. Free teaser: simulate_free.
- `simulate_free`: FREE. Method + revert flag + risk level + predicted effect types for a transaction. Real result, no wallet. Upgrade to simulate for the full predicted deltas + all risk flags.
- `token_safety`: PAID $0.02 (x402, USDC on Base). Multi-chain token honeypot/rug check aggregating GoPlus token-security + honeypot.is buy/sell-tax simulation into a normalized 0-100 risk score with explainable reasons: honeypot/can't-sell, buy/sell tax, mint/blacklist/pausable/ownership privileges, top-holder concentration, LP-lock, contract verified/bytecode. Descriptive facts only — NOT a buy/sell signal. Without payment returns the x402 challenge; pass x_payment to settle. Free teaser: token_safety_free.
- `token_safety_free`: FREE. Score band + top-line honeypot/tax/privilege flags for a token {address, chain}. Real result, no wallet. Upgrade to token_safety for the full numeric breakdown.
