## Trust

- hygiene: 100
- liveness: 99
- freshness: 100

- drivers: +repository +namespace-matches-repo +website +reachable +uptime-97% +updated-10d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 85/100 (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: 86 (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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: coldread_verify_report (destructiveHint, idempotentHint, openWorldHint); coldread_check (destructiveHint, idempotentHint); coldread_get_report (destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 323 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: 3, about 323 tokens to load them all
- tool set hash: d1d965777d168e327ac78bd4422523eb
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.something-agent/coldread.svg)](https://protogrid.dev/servers/io.github.something-agent/coldread)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

## Tools (3)

- `coldread_check`: Before paying an x402 seller: one signed, independent report combining a 402-challenge lint, signed-offer and signer-authorization checks, an ERC-8004 identity lookup and a labelled Base USDC payer summary over the last ~28 h. Read-only; never pays. Free.
- `coldread_get_report`: Fetch a stored signed report by its sha256 digest (reports are kept 90 days).
- `coldread_verify_report`: Check that a ColdRead report envelope is unmodified (JCS + sha256) and signed by a published ColdRead key. Pass the whole envelope {report, digest, signature}.
