On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 1051 ms.

• Its tools do none of the product's use cases we checked: generate hreflang tags for every page and locale; estimate translation cost from page count and word count; track which translated pages are stale per locale.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• dataset_columns

• dataset_row

  The rows of the Hreflangly dataset where a column equals a value exactly (case-insensitive).

• dataset_compare

  The rows of the Hreflangly dataset whose column is any of the given values, in the order given — for "X vs Y" questions.

• dataset_stats

  count, min, max, mean, median and sum of a numeric column of the Hreflangly dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).

• dataset_top

  The highest (or lowest) rows of the Hreflangly dataset by a numeric column — "which is the most/least X".
