Server Details
19 zero-setup utilities: JSON, regex, cron, hash, base64, CSV, JWT, UUID, YAML, semver, time.
Glama couldn't complete the latest health check. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.
If you are the author, claim ownership, then add or update a test profile under Admin → Test Profile.

TDQS
Scored across 19 tools
Each tool targets a distinct data format or utility operation: semver tools are separated by bump/compare/max/satisfies, and encoding/parsing tools are clearly scoped to base64, CSV, JSON, YAML, etc. There is no meaningful overlap between any two tools.
Tool names consistently use lowercase snake_case and mostly follow a domain_then_operation pattern like csv_parse, hash_compute, and time_convert. A few names such as password_strength and text_diff use noun outcomes rather than verbs, which is a minor deviation from the otherwise clear pattern.
At 19 tools, the server sits at the upper edge of what feels focused for a general-purpose utility toolkit. Each tool is individually useful, but the broad spread across unrelated domains makes the set feel more like a collection of one-off helpers than a tightly scoped API.
Because the server is a general-purpose utility toolkit rather than a CRUD service, completeness means covering common developer tasks, and it does cover most core formats and operations. Minor gaps like URL encoding/decoding and XML/TOML parsing exist, but the included categories are largely self-contained and usable.
