## Trust

- hygiene: 100
- liveness: 98
- freshness: 100

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 86/100 (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: 88 (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
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_transaction (destructiveHint); get_token (destructiveHint)
- pass `tools.token_cost`: about 324 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### 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
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 2, about 324 tokens to load them all
- tool set hash: 64f5e86b49a0d6f8cc79a76fabdceb8e
- badge: [![protogrid quality](https://protogrid.dev/badge/io.altscan/explorers.svg)](https://protogrid.dev/servers/io.altscan/explorers)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

## Tools (2)

- `get_token`: A BNB Chain or Ethereum token contract: name, symbol, decimals, total supply, indexed holder count, and `lookalike`: the well-known token (e.g. USDT) whose name or symbol it imitates, with that token's real contract. `lookalike: null` only means no match against a short list of well-known tokens; it is not a safety verdict.
- `get_transaction`: One BNB Chain or Ethereum transaction by hash: from, to, value (wei), gas, status. Recent transactions come from the explorer index; older ones are read from the chain (`source` says which). `pending: true` means no receipt yet, and fields the node did not report are null. Logs and decoded calls are not included.
