Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| json_toolsA | Validate and reshape a JSON string. mode=format pretty-prints, minify compacts, sort_keys recursively alphabetizes object keys. Returns a clear error for invalid JSON. |
| regex_testA | Run a JavaScript regular expression against a subject string and return each match with its index, positional capture groups, and any named groups. Flags are honored exactly: without the g flag only the first match is returned; with g, all matches. |
| hash_textA | Compute a cryptographic digest (hex) of UTF-8 text. |
| uuid_generateA | Generate one or more RFC-4122 version-4 UUIDs (1–100). |
| base64_transformA | Encode or decode text as Base64, with an optional URL-safe alphabet. |
| jwt_inspectA | Decode a JWT's header and payload and report whether a signature segment is present and whether the token is expired. Does NOT verify the signature — decoding only. |

TDQS
Scored across 6 tools
Each tool has a clearly distinct purpose: base64 encoding/decoding, hashing, JSON formatting/validation, JWT inspection, regex testing, and UUID generation. No overlap.
Tools follow snake_case with descriptive names, mostly verb_noun or noun_verb pattern. 'json_tools' is slightly generic but still consistent with others.
6 tools is well-scoped for a developer utilities server. Each tool earns its place without being too few or too many.
Covers common text/format utilities (Base64, hash, JSON, JWT, regex, UUID). Missing URL encoding/decoding but still sufficient for typical use.
