## 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: hash_hmac (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); hash_digest (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 301 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`: 1 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: 2, about 301 tokens to load them all
- tool set hash: 3a477d9b07de700df01556591e6bffcf
- tools last changed: 2026-09-28T23:28:20.648Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.apished/hash-digest-tool.svg)](https://protogrid.dev/servers/com.apished/hash-digest-tool)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-28 `hash_hmac` added
  - Computes an HMAC of input (decoded per encoding) using algo: md5, sha1, sha256, or sha512 (crc32 isn't offered — it's a checksum, not a cryptographic primitive HMAC composes with). key is used as its raw UTF-8 bytes, not decoded per encoding. Returns the MAC as lowercase hex.

## Tools (2)

- `hash_digest`: Computes a hash digest of input (decoded per encoding: "text" default, "base64", or "hex") using algo: md5, sha1, sha256, sha512, or crc32. Returns the digest as lowercase hex.
- `hash_hmac`: Computes an HMAC of input (decoded per encoding) using algo: md5, sha1, sha256, or sha512 (crc32 isn't offered — it's a checksum, not a cryptographic primitive HMAC composes with). key is used as its raw UTF-8 bytes, not decoded per encoding. Returns the MAC as lowercase hex.
