## Quality 72/100 (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: 93 (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`: 10 of 10 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 2 of 10 tools declare all four hints; missing: format_json (idempotentHint); generate_qr_code (idempotentHint); convert_units (idempotentHint); …
- pass `tools.token_cost`: about 2,062 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 10 tool changes in 30 days
- fail `stability.rug_pull`: 9 tools kept their name but changed most of their description in 30 days; review before trusting them

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know simplyutils-mcp@1.0.2

- tools: 10, about 2,062 tokens to load them all
- tool set hash: 1737fd4c7291e508e249593809c54de8
- tools last changed: 2026-10-27T16:01:00.946Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Notysoty/simplyutils-mcp.svg)](https://protogrid.dev/servers/io.github.Notysoty/simplyutils-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-27 `count_words` changed (description, inputSchema) **meaning changed**
  - before: Count words, characters, sentences and paragraphs in text, with an estimated reading time.
  - after: Count words, characters (with and without spaces), sentences and paragraphs, and estimate reading time at 238 words per minute. Words are runs of letters or digits in any language; hyphenated words and contractions count once. Paragraphs are separated by blank lines. Input up to 100 KB.
- 2026-10-27 `convert_timestamp` changed (description) **meaning changed**
  - before: Convert a Unix timestamp (seconds or milliseconds) or a date string to Unix seconds, milliseconds, ISO 8601, UTC and a chosen time zone.
  - after: Convert a Unix timestamp or a date to Unix seconds, Unix milliseconds, ISO 8601 (UTC), an HTTP-style UTC string and a readable date in the chosen time zone. Numbers with 13 or more digits are read as milliseconds, shorter ones as seconds. Dates without a time zone are read as UTC. Errors are returned for unreadable dates and unknown time zones.
- 2026-10-27 `test_regex` changed (description, inputSchema) **meaning changed**
  - before: Run a JavaScript regular expression against text and list every match with its position and capture groups (up to 200 matches, 0.5 s limit).
  - after: Run a JavaScript (ECMAScript) regular expression against text. Returns the match count and, for each match, the matched text, its 0-based index, numbered capture groups and named groups. Returns 'No matches.' when nothing matches. All matches are listed (the g flag is added automatically), up to 200. Invalid patterns or flags return an error explaining why; patterns that run longer than 0.5 seconds are stopped with an error. Text up to 100 KB.
- 2026-10-27 `base64` changed (description, inputSchema) **meaning changed**
  - before: Encode UTF-8 text to Base64 (standard or URL-safe) or decode Base64 back to text.
  - after: Encode text (as UTF-8) to Base64, or decode Base64 back to text, and return the result. Decoding accepts standard and URL-safe alphabets and ignores whitespace; invalid Base64 returns an error. Bytes that are not valid UTF-8 are shown as replacement characters. Input up to 100 KB.
- 2026-10-27 `hash_text` changed (description, inputSchema) **meaning changed**
  - before: Hash UTF-8 text with MD5, SHA-1, SHA-256, SHA-384 or SHA-512 and return the hex digest. MD5 and SHA-1 are for checksums only, not security.
  - after: Hash text (encoded as UTF-8) and return a line such as 'sha256: ba78...' with the lowercase hex digest. The same input always gives the same hash. MD5 and SHA-1 are only for checksums, not security; do not use plain hashes to store passwords. Input up to 100 KB.
- 2026-10-27 `generate_uuid` changed (description, inputSchema) **meaning changed**
  - before: Generate random version 4 UUIDs.
  - after: Generate random version 4 UUIDs (RFC 9562) in lowercase 8-4-4-4-12 form, one per line. Every call gives new values.
- 2026-10-27 `generate_password` changed (description, inputSchema) **meaning changed**
  - before: Generate random passwords with a cryptographically secure generator. Each chosen character set appears at least once.
  - after: Generate random passwords with Node's cryptographically secure generator. Each enabled character set appears at least once and the result is shuffled. Returns one password per line; every call gives new results. An error is returned if all character sets are turned off. Passwords are not stored or logged.
- 2026-10-27 `convert_units` changed (description, inputSchema)
  - before: Convert a value between units of the same category. Units (symbol or name): length: m, km, mi, ft, in, cm, mm, yd, nmi; weight: kg, g, lb, oz, t, mg, st; temperature: °C, °F, K; volume: L, mL, gal, fl oz, cup, tbsp, m³; speed: km/h, mph, m/s, kn, ft/s; area: m², km², mi², ft², ac, ha; data: B, KB, MB, GB, TB, bit, KiB, MiB, GiB, TiB; time: s, min, h, d, wk, mo, yr, ms.
  - after: Convert a number between two units of the same category and return a line such as "5 mi = 8.04672 km" (up to 10 significant digits). Units are matched by symbol or name, case-insensitive. Errors are returned for unknown units, units from another category, non-numeric values and temperatures below absolute zero. Months are 1/12 of a 365-day year. Units by category (symbols): length: m, km, mi, ft, in, cm, mm, yd, nmi; weight: kg, g, lb, oz, t, mg, st; temperature: °C, °F, K; volume: L, mL, gal, fl oz, cup, tbsp, m³; speed: km/h, mph, m/s, kn, ft/s; area: m², km², mi², ft², ac, ha; data: B, KB, MB, GB, TB, bit, KiB, MiB, GiB, TiB; time: s, min, h, d, wk, mo, yr, ms.
- 2026-10-27 `generate_qr_code` changed (description, inputSchema) **meaning changed**
  - before: Make a static QR code for a link or text (up to 800 bytes). Returns a PNG image and the SVG markup. Static codes never expire.
  - after: Make a static QR code for a link or any text, up to 800 UTF-8 bytes. Returns a 512 px PNG image plus the SVG markup. The data is stored in the code itself, so it never expires and needs no account. Light-on-dark colors are allowed, but some older scanners need dark on light. Errors are returned for empty text, content over 800 bytes, or colors that are not six-digit hex.
- 2026-10-27 `format_json` changed (description, inputSchema) **meaning changed**
  - before: Validate JSON and pretty-print or minify it, optionally sorting object keys. Returns the error position for invalid JSON.
  - after: Validate JSON and return it pretty-printed or minified, optionally with object keys sorted A-Z (recursively; array order is kept). Returns the formatted JSON as text. Invalid JSON returns an error naming the problem and its position. Input up to 100 KB.
