Server Details

EPW/DDY weather files - TMY/AMY/CMIP6 morphing, UHI, events, smoke. 3 of 4 tools anon-free.

The last two health checks of this connector failed. 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

A4.4/5.0

Scored 2026-09-11 01:16 across 6 tools

Disambiguation5/5

Each tool targets a distinct purpose: analysis, charting, interactive exploration, station search, file generation, and bundle preview. Overlap is explicitly addressed (e.g., explore vs. analyze), so an agent can reliably choose the right tool.

Naming Consistency5/5

All six tools follow a consistent verb_noun pattern (analyze_weather, chart_weather, explore_design_conditions, find_station, generate_weather_file, preview_forge_bundle). No mixed conventions or vague verbs.

Tool Count5/5

With exactly 6 tools, the server is well-scoped for its domain: discovery, analysis, visualization, generation, and purchase preview. Each tool earns its place without redundancy or bloat.

Completeness5/5

The tool surface covers the full workflow: finding stations, analyzing data, generating files, creating charts, and previewing purchases. There are no obvious gaps—users can go from station discovery to final file acquisition and analysis without dead ends.
