TDQS

A4.1/5.0

Scored 2026-10-24 07:10 across 28 tools

Disambiguation4/5

Tool families are mostly cleanly separated: scenario creation/build/run, run polling/details, and observation CRUD/comparison each have distinct scopes. The main near-overlaps are get_run vs get_run_status and build_scenario vs start_simulation, but the descriptions make the boundaries explicit enough.

Naming Consistency5/5

Every tool uses snake_case and a predictable verb_noun or verb_noun_phrase form (list_*, get_*, create_*, add_*, set_*, start_*, etc.). No mixed conventions or vague names appear.

Tool Count3/5

28 tools is high and exceeds the typical comfortable range, though the domain is broad (projects, terrain, inputs, scenarios, runs, observations, time series, comparisons). Most tools correspond to real operations, but some lifecycle/helper operations could likely be consolidated.

Completeness3/5

Core workflows are covered, but there are notable lifecycle gaps: projects and scenarios have create/get/list/build/run paths but no update or delete tools; time series support create/list but not update/delete; there is no detach/remove input operation. Agents can work around some of these in the browser, but the MCP surface is not fully complete.

Tool Schema Changelog

Recent tool additions, removals, and schema changes observed during successful MCP inspections.

Changedcreate_time_series2 fields changed

addedInput schema / properties / hold_last_value

Added value: +{
+  "default": false,
+  "description": "Set true ONLY when the last value is meant to be held after the series ends. A hydrograph or hyetograph whose last value is not 0 is refused (TRAILING_VALUE_HELD) unless this is true: end the series with a 0 row instead, unless holding is really intended.",
+  "type": "boolean"
+}

changedInput schema / properties / units / description

Previous value: -"Display label for the values, e.g. 'mm/hr', 'm^3/s', 'm' (optional)"New value: +"Units of the values. REQUIRED for hyetograph ('mm/hr' or 'mm/h'), hydrograph ('m3/s', 'm^3/s' or 'cumec') and stage ('m'): the engine reads those units whatever the label says, so a mismatch is refused before anything is sent. Free for generic."

addedInput schema / properties / consent_timeout_seconds

Added value: +{
+  "default": 0,
+  "description": "When the run needs the person's consent (CONSENT_REQUIRED), how long this call keeps polling the run for their click before it returns (ceiling 280). Default 0: return the consent link at once, so you can give it to them — they cannot press a button they have not been shown.",

addedInput schema / properties / poll_interval_seconds

Added value: +{
+  "default": 5,
