Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security63

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability76

100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
AI-judged instruction clarity (excellent).Pass
Context-footprint check failed: tool/resource definitions use about 1451 tokens (~241/item across 6 items; 5 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage100

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
100% of tool parameters carry a description.Pass
Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 5 exposed · ~1,095 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

compare_models Compare models at a point (scoreboard) ~400

Sample one variable at a point across many models and summarize per-time cross-model spread (min/max/mean/spread). Sources default to every live source carrying the variable; pass a comma-separated `sources` to pin the set. Canonical variable ids: t2m = 2 m air temperature (K), u10 = 10 m U wind component (m/s), v10 = 10 m V wind component (m/s), wind_speed = 10 m wind speed, derived hypot(u10, v10) (m/s), tp = total precipitation over the step (kg m-2, mm-equivalent), tcc = total cloud cover (fraction 0-1), ssrd = surface downward shortwave radiation (W m-2), msl = mean sea level pressure (Pa) (availability varies by source — see GET /v1/sources). Common aliases are accepted case-insensitively and normalized to these ids: temperature/temperature_2m/temp -> t2m, wind/windspeed/wind_speed_10m -> wind_speed, u10m/v10m -> u10/v10, precip/precipitation/rain -> tp, cloud/clouds/cloud_cover -> tcc, solar/radiation/shortwave -> ssrd, pressure/mslp/sea_level_pressure -> msl. The output series always carries the canonical id.

Input Output Examples

Name	Type	Req	Description
init_time	—	—	Run init (UTC ISO 8601); omit for each source's latest run.
lat	number	yes	Latitude, degrees north.
lon	number	yes	Longitude, degrees east.
sources	—	—	Comma-separated `source_id`s; omit to use every live source with the variable.
variable	string	yes	A single variable id, e.g. t2m, tp, tcc, ssrd (or an alias like temperature_2m/precipitation — normalized to the canonical id).

Name	Type	Req	Description
consensus	array	yes	Per-valid_time cross-model spread, ascending.
lat	number	yes	—
lon	number	yes	—
missing	array	yes	Requested/eligible sources with no data for this variable.

units	string	yes	—
variable	string	yes	—

No examples provided.

list_runs List stored runs ~58

Stored run init times for a source, newest first (UTC ISO 8601). Pass one to pin a tool to that run.

Input Output Examples

Name	Type	Req	Description
source_id	string	yes	A `source_id` from list_sources, e.g. `gfs`.

Name	Type	Req	Description
result	array	yes	—

No examples provided.

list_sources List forecast sources ~42

Input schema present but exposes no named parameters.

Name	Type	Req	Description
result	array	yes	—

No examples provided.

point_forecast Point forecast ~482

Full forecast horizon of one model at a single point (bilinear grid sample). source_id is OPTIONAL: omit it and a sensible live source is chosen (prefers gfs, then ifs_open) and returned as `source_id`. Omit init_time for the latest run; omit variables for all stored variables plus derived wind_speed. Canonical variable ids: t2m = 2 m air temperature (K), u10 = 10 m U wind component (m/s), v10 = 10 m V wind component (m/s), wind_speed = 10 m wind speed, derived hypot(u10, v10) (m/s), tp = total precipitation over the step (kg m-2, mm-equivalent), tcc = total cloud cover (fraction 0-1), ssrd = surface downward shortwave radiation (W m-2), msl = mean sea level pressure (Pa) (availability varies by source — see GET /v1/sources). Common aliases are accepted case-insensitively and normalized to these ids: temperature/temperature_2m/temp -> t2m, wind/windspeed/wind_speed_10m -> wind_speed, u10m/v10m -> u10/v10, precip/precipitation/rain -> tp, cloud/clouds/cloud_cover -> tcc, solar/radiation/shortwave -> ssrd, pressure/mslp/sea_level_pressure -> msl.

lon	number	yes	Longitude, degrees east (normalized to [-180,180)).

variables	—	—	Comma-separated variable ids (t2m, u10, v10, wind_speed, tp, tcc, ssrd, msl); omit for all + wind_speed. Common aliases like temperature_2m/windspeed/precipitation/cloud/solar/pressure are accepted (…

Name	Type	Req	Description
init_time	string	yes	Run init time (UTC ISO 8601) actually sampled.
