## Quality 70/100 (needs work)

### 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: 64 (weight 30)

- warn `tools.descriptions`: 1 of 20 tools have a description under 20 characters
- 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: base_address_inspect (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); base_contract_risk (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ethereum_tx_explain (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,912 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 19 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: 20, about 1,912 tokens to load them all
- tool set hash: ef18fdbd9e0640dcf7ce082dbea59240
- tools last changed: 2026-10-17T03:37:08.101Z
- badge: [![protogrid quality](https://protogrid.dev/badge/app.vercel.automaton-tx-explainer/base-tools.svg)](https://protogrid.dev/servers/app.vercel.automaton-tx-explainer/base-tools)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
