## 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: get_wallet_balances (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_token_info (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_token (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,108 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 1,108 tokens to load them all
- tool set hash: 39c0d4a9da846999713363cac975051a
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.workers.safe-or-scam.scam-check/safe-or-scam.svg)](https://protogrid.dev/servers/dev.workers.safe-or-scam.scam-check/safe-or-scam)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (8)

- `check_email`: Check an email address before sending or signing someone up: valid format, domain exists and accepts mail (MX), throwaway/disposable domain, typo suggestions (gmial.com → gmail.com), role addresses (info@, support@), SPF/DMARC. Returns valid / risky / invalid with reasons.
- `check_token`: Is this crypto token a scam? Honeypot buy/sell simulation, hidden taxes, mint/freeze authority, hidden owner, blacklist, whale concentration, liquidity lock. Returns red/yellow/green with reasons. EVM chains + Solana.
- `check_wallet`: Is it safe to send crypto to this address, and is this wallet exposed? Checks scam, phishing, theft, sanctions and mixer links; risky or malicious token approvals (who can drain the wallet); contract vs personal wallet; brand-new 'poisoned' look-alike addresses. Returns red/yellow/green with reasons. EVM chains + Solana.
- `check_website`: Is this website a crypto scam or phishing page? Phishing databases, domain age, look-alikes of 45+ crypto brands (MetaMask, Phantom, Binance...), seed-phrase requests, wallet-drainer code. Returns red/yellow/green with reasons.
- `get_token_info`: Read a token's on-chain details: name, symbol, decimals, total supply. Solana: supply, decimals, mint authority and freeze authority.
- `get_transaction`: Look up a transaction by hash: success/failed/pending, confirmations, time, sender, receiver, value, fee, method, decoded token and NFT transfers, and token approvals it granted (flags unlimited approvals). Solana: balance changes per account.
- `get_wallet_balances`: Get a wallet's balances: native coin (ETH, BNB, POL, AVAX, SOL) and tokens. Solana: every SPL token held. EVM: popular tokens on the chain plus any token addresses you pass. Also returns transactions sent and whether the address is a contract.
- `read_webpage`: Fetch any public web page and return clean Markdown of its main content (headings, lists, links, code), plus title and description. Strips menus, footers, ads and scripts so it is ready for an LLM. Not charged if the page can't be fetched.
