Tools observed via MCP handshake

time_convert — Convert and explain a date/time: epoch ms/s, ISO 8601, or relative ("2h ago"). Cross-convert timezones (IANA names like America/New_York). Naive inputs treated
json_inspect — Parse, validate, and pretty-print JSON strings. Returns whether the input is valid JSON, the parsed data type, keys, and formatted output.
regex_test — Test a regular expression against an input string. Returns all matches with their positions and capturing groups.
cron_parse — Parse a cron expression (5 fields) and explain the schedule. Computes and shows the next 5 run times in ISO format.
hash_compute — Compute a cryptographic hash of input data. Supports MD5, SHA1, SHA256, and SHA512. Returns the hex digest.
base64_encode — Encode or decode Base64 data. Useful for binary data, token inspection, and data serialization.
url_analyze — Parse and analyze a URL. Returns protocol, hostname, port, path, query parameters, fragment, and validation status.
color_convert — Convert a color between hex, RGB, HSL, and named formats. Returns the color in all supported representations.
text_diff — Compare two texts and show the differences line by line. Returns added/removed/unchanged counts and the diff output.
csv_parse — Parse CSV/TSV/semicolon/pipe-delimited data into rows. Returns column headers, row/column counts, delimiter used, column consistency check, and a JSON preview o
jwt_decode — Decode and validate a JWT. Returns header, payload, algorithm, signature presence, and — when a secret is provided — whether an HMAC-SHA256/384/512 signature ve
markdown_to_html — Convert Markdown to HTML. Supports ATX headings, fenced code blocks, ordered/unordered lists, blockquotes, horizontal rules, paragraphs, inline code, bold/itali
uuid_mint — Generate RFC 4122 version 4 UUIDs and/or cryptographically random URL-safe tokens. Batch count is clamped to 1-10.
password_strength — Analyze password strength. Returns a 0-100 score, rating, length, character-class variety, Shannon entropy, estimated crack time, issues, positives, and improve
yaml_parse — Parse YAML into JSON. Converts YAML documents (maps, lists, nesting, flow collections {a: 1}, [1,2], inline scalars, multi-document streams with ---) into a JSO
semver_compare — Compare two semantic versions with correct SemVer 2.0.0 precedence (e.g. 1.10.0 > 1.9.0 — plain string sort is wrong). Returns -1/0/1, the human relation, and t
semver_satisfies — Test whether a version satisfies an npm-style version range (caret ^, tilde ~, >=, <=, <, >, =, hyphen ranges, x-wildcards like 1.2.x, &&/space AND and || OR).
semver_bump — Increment a semantic version to the next release level: major, minor, patch, premajor, preminor, prepatch, or prerelease. An optional identifier (e.g. beta) see
semver_max — Pick the BEST version from a comma-separated list that satisfies a range — the highest satisfying version (upgrade target). Correctly excludes inapplicable prer
