- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 5836 tokens (~171/item across 34 items; 34 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability check failed: schema churn in the 1 day we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 34 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 35 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### 2026-09-26 (score 71)

First indexed and scored.

## MCP tools (34)

### `health` (~56 tokens)

Service health

Free. Liveness and store readiness. Returns 200 whenever the server is up. `ready` is false while the store is still ingesting after a restart; paid endpoints answer 503 (and take no payment) until it is true.

### `catalog` (~91 tokens)

Data catalog

Free. Providers, regions, coverage window and event counts. One row per (provider, region) with raw-event coverage (instance types, events, first/last event) and legacy-history coverage (daily and monthly date ranges), plus `sources`, the legend explaining every `source` value returned by /spot/daily and /spot/monthly. Use the `region` values here verbatim in every other call.

### `instances` (~191 tokens)

Instance types in a region

Free. Instance types available in a region. Exact type names with per-type coverage: raw events (`events`, `first_event`, `last_event`; zero/null for types that only exist in the legacy history) and legacy history ranges (`history_daily_from/to`, `history_monthly_from/to`). Optional `prefix` narrows the list (for example `c5.` or `n2-`).

Input parameters:

- `prefix` (string): Case-sensitive prefix filter on the type name.
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

### `spot_events` (~397 tokens)

Spot price events

Paid (0.01 USDC per call). Raw spot price-change events for one instance type. Every price change for the type in the window, with exact timestamp, availability zone and product (OS). Sorted by time. Repeated identical prices are dropped by default (`include_repeats=true` keeps them). Up to `limit` rows; when `truncated` is true, continue with `from` = `next_from`.

Input parameters:

- `az` (string): Restrict to one availability zone / zone id (for example `use1-az1`). Default: all zones.
- `from` (string): Start of the window (inclusive), ISO 8601 UTC. Default: 7 days before `to`.
- `include_repeats` (boolean): Keep events whose price equals the previous event of the same (az, product) series. Default false.
- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `limit` (integer): Maximum rows to return (1 to 10000). Default 5000.
- `product` (string): Restrict to one product / OS string (for example `Linux/UNIX`, `Spot`, `Linux`). Default: all.
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1
- `to` (string): End of the window (exclusive), ISO 8601 UTC. Default: now.

### `spot_hourly` (~277 tokens)

Hourly spot bars

Paid (0.01 USDC per call). Hourly time-weighted OHLC bars for one instance type. Per-zone series are bucketed by UTC hour with time weighting (a price counts for as long as it was in force), then collapsed across zones: open/close/avg are the median across zones, high is the max, low is the min. Window is capped at 366 days.

Input parameters:

- `from` (string): Start of the window (inclusive), ISO 8601 UTC. Default: 30 days before `to`.
- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1
- `to` (string): End of the window (exclusive), ISO 8601 UTC. Default: now.

### `spot_daily` (~358 tokens)

Daily spot history

Paid (0.05 USDC per call). Full daily history for one instance type, all eras stitched. One row per UTC day from the earliest data for the type to now. Rows dated before the type's first raw event come from the legacy history (`source` = `pauley`: measured 2022-05 to 2024-01 AWS, open/high/low/close present on days the price moved; `titans`: daily average only, 2024 to 2026). Rows from `direct_from` on are time-weighted, zone-collapsed bars from the raw event store (`source` = `direct`, same method as /spot/hourly; `avg` equals the public dashboard value). open/high/low/close are null where the source only has an average.

Input parameters:

- `from` (string): Start of the window (inclusive), ISO 8601 UTC. Default: the earliest row for the type.
- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1
- `to` (string): End of the window (exclusive), ISO 8601 UTC. Default: now.

### `spot_monthly` (~412 tokens)

Monthly spot history

Paid (0.05 USDC per call). Full monthly history for one instance type, back to 2014 for legacy AWS types. Calendar months from the earliest data to now. `months` is the curated series: `uscisi-adjusted` months (2017 to 2022-04, AWS types with a stable correction factor, average only), then months rolled up from the daily series (`pauley`, `titans`, `direct`: `avg` = median of daily averages, open/close from the first/last day, high/low the extremes, `days` = days covered, `source` = the source covering most days). `archive` (AWS, default on) is the USC/ISI monthly dataset 2014-02 to 2023-12 as published, with open/high/low/close, for 51 legacy types: third-party, mixes OS products, provenance partly unverified; returned separately so it never silently blends into the curated series.

Input parameters:

- `from` (string): First month (inclusive), YYYY-MM-DD (use the 1st). Default: earliest.
- `include_archive` (boolean): Include the raw USC/ISI archive rows in `archive`. Default true.
- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1
- `to` (string): Last month (inclusive), YYYY-MM-DD. Default: latest.

### `spot_latest` (~239 tokens)

Current spot price per zone

Paid (0.01 USDC per call). Price currently in force per zone and product for one instance type. The most recent event of every (zone, product) series of the type, with its timestamp and age. A price is only meaningful while the provider still offers the type; AWS series older than ~10 days are likely retired, GCP/Azure reprice rarely so old timestamps are normal. For every type in a region at once use /spot/snapshot.

Input parameters:

- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

### `spot_snapshot` (~180 tokens)

Region spot snapshot

Paid (0.10 USDC per call). Current price of every instance type, zone and product in a whole region, in one call. Bulk snapshot: the most recent event of every series in the region (about 6,000 rows for an AWS region), with timestamp and age per row. Same semantics as /spot/latest. Priced higher because one call returns the entire current price surface of the region.

Input parameters:

- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

### `ondemand` (~278 tokens)

On-demand price history

Paid (0.01 USDC per call). On-demand list-price history of one instance type. Change-point series: one row per day the on-demand (pay-as-you-go) hourly list price changed; `current` is the price in force. AWS: Linux, shared tenancy, from the AWS Price List API, refreshed weekly, since 2024-01 (every AWS region in /catalog). Azure: every Linux VM SKU from the public Retail Prices API, refreshed daily, since 2026-09-13 (every Azure region in /catalog). GCP: the TITANS-era series (2024 to 2026-08), not refreshed.

Input parameters:

- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

### `ondemand_snapshot` (~120 tokens)

Region on-demand snapshot

Paid (0.10 USDC per call). Current on-demand list price of every instance type in a region.

Input parameters:

- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

### `reserved` (~340 tokens)

Reserved price history

Paid (0.01 USDC per call). Reserved / reservation price history of one instance type (AWS standard RIs 1y/3y no-upfront/all-upfront; Azure reservations 1y/3y). Effective hourly USD with any upfront amortized over the term, as change-point series per `ri_type` (`ri_1y_no_upfront_standard`, `ri_1y_all_upfront_standard`, `ri_3y_no_upfront_standard`, `ri_3y_all_upfront_standard`; GCP `cud_1y`, `cud_3y`). AWS: Linux, shared tenancy, history back to 2016 for the original three regions, weekly refresh from the AWS Price List API. Azure: all-upfront reservations from the public Retail Prices API, daily, since 2026-09-13. GCP: resource-based committed-use discounts from the Cloud Billing Catalog (vCPU, RAM and GPU commitment SKUs), daily, since 2026-09-13.

Input parameters:

- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string): Provider: `aws` (default), `azure` or `gcp`.
- `region` (string, required): Region slug (for example `us-east-1`, `us-east` for Azure, `us-central1` for GCP). Example: us-east-1

Input parameters:

- `provider` (string): Provider: `aws` (default), `azure` or `gcp`.
- `region` (string, required): Region slug (for example `us-east-1`, `us-east` for Azure, `us-central1` for GCP). Example: us-east-1

### `gpu_models` (~70 tokens)

GPU models

Free. GPU models with rental quotes, and which providers quote them. Normalized model names (use verbatim as `gpu`), number of providers quoting each, quote counts, first/last snapshot day, the lowest observed USD per GPU-hour, and which hyperscaler spot instance families map to the model.

### `gpu_quotes` (~298 tokens)

GPU rental quotes

Paid (0.01 USDC per call). Latest rental quotes for one GPU model across neo-clouds, marketplaces and other clouds. One row per quote in each provider's latest daily snapshot: provider, market (`ondemand`, `spot` = interruptible, `bid` = marketplace minimum bid, `secure`/`community` = RunPod tiers), GPUs in the quoted unit, USD per GPU-hour, quoted unit price, region where the provider exposes one, and provider-specific detail in `extra` (marketplace host reliability, VRAM, stock status). Sources are each provider's public price feed or page (Vast.ai: the cheapest 64 offers per model, on-demand and bid); /gpu/models lists who quotes each model. Snapshots are taken several times a day.

Input parameters:

- `gpu` (string, required): Normalized GPU model from /gpu/models, e.g. `H100 SXM`, `H200`, `B200`, `A100 SXM 80GB`, `L40S`, `RTX 4090`. Example: H100 SXM

### `gpu_index` (~212 tokens)

GPU rental index

Paid (0.05 USDC per call). Daily USD per GPU-hour index per provider and market for one GPU model, with hyperscaler spot legs. For each snapshot day and (provider, market): number of quotes and the lowest, median, mean and highest USD per GPU-hour. Rows with provider `aws-spot` or `gcp-spot` are computed from our own spot price events for the instance family that carries the GPU (time-weighted daily bar divided by GPUs per node, per region), so the neo-cloud market and hyperscaler spot are comparable in one series. Quote history starts 2026-09-13; hyperscaler spot legs reach back to the start of our event data.

Input parameters:

- `from` (string): First day (inclusive), YYYY-MM-DD. Default: earliest.
- `gpu` (string, required): Normalized GPU model from /gpu/models. Example: H100 SXM
- `to` (string): Last day (inclusive), YYYY-MM-DD. Default: latest.

### `gpu_snapshot` (~45 tokens)

### `status` (~56 tokens)

Data freshness

Free. Freshness of every data source. Per source: last successful snapshot or event, staleness in days, and the public URL it is read from. Use it to decide whether a fixing or quote is current before paying for it.

### `index_tickers` (~63 tokens)

Index tickers

Free. Every index ticker, its segment and definition. Tickers are CX.<MODEL>.<SEGMENT> (for example CX.H100SXM.NEO) or CX.<MODEL>.SPOT.<REGION>. Includes the segment membership lists and the methodology version.

### `index_fixing` (~186 tokens)

Index fixing

Paid (0.01 USDC per call). One day's fixing for a ticker: median USD per GPU-hour of eligible quotes, with low, high and count. Quote segments (MKT, AGG, NEO, INT, EXE, HYP) fix from that day's snapshots; the default day is the latest snapshot. SPOT fixes from the full UTC day of spot events, so the default is yesterday; SPOT composites carry per-region values and spread_vs_neo. See /methodology for eligibility and aggregation.

Input parameters:

- `day` (string): Fixing day, YYYY-MM-DD. Default: latest available.
- `ticker` (string, required): Ticker from /index/tickers, e.g. `CX.H100SXM.NEO` or `CX.H100SXM.SPOT.US-EAST-1`. Example: CX.H100SXM.NEO

### `index_history` (~152 tokens)

Index history

Paid (0.05 USDC per call). Daily fixings for a ticker over a date range. Quote segments start 2026-09-13. SPOT tickers reach back to the start of the spot series (AWS daily from 2022-05-31 for A100, V100, T4, A10; from 2023-07 for H100), each row carrying its data source.

Input parameters:

- `from` (string): First day, YYYY-MM-DD. Default: earliest.
- `ticker` (string, required): Ticker from /index/tickers. Example: CX.H100SXM.NEO
- `to` (string): Last day, YYYY-MM-DD. Default: today.

### `index_board` (~47 tokens)

- `ticker` (string, required): Token ticker. Example: CX.TOK.FRONTIER.BLEND
- `to` (string): YYYY-MM-DD.

### `tokens_board` (~49 tokens)

LLM token board

Paid (0.10 USDC per call). Every model's input, output and blended fixing for one day, plus the frontier basket.

Input parameters:

- `day` (string): YYYY-MM-DD; default latest.

### `term_instance` (~273 tokens)

Instance price ladder

Paid (0.01 USDC per call). Price ladder for one instance type: spot, on-demand, 1-year and 3-year commitments, with discounts. Current prices from our series: spot median across zones (where spot events exist), on-demand list price, and reserved/reservation terms as effective hourly with upfront amortized. `discount_pct` is relative to on-demand. AWS carries four reserved terms (1y/3y × no/all upfront), Azure two (1y/3y all upfront), GCP two resource-based committed-use terms (`cud_1y`, `cud_3y`, no upfront).

Input parameters:

- `instance` (string, required): Instance / machine / SKU type name exactly as listed by /instances (for example `c5.large`, `n2-standard-4`, `D2s_v5`). Example: c5.large
- `provider` (string, required): Cloud provider. One of `aws`, `gcp`, `azure`.
- `region` (string, required): Region slug as listed by /catalog (for example `us-east-1` for AWS, `us-central1` for GCP, `us-east` for Azure). Azure slugs map to `eastus`, `westus2`, `westeurope`. Example: us-east-1

### `term` (~171 tokens)

GPU term structure

Paid (0.05 USDC per call). Term structure per hyperscaler for one GPU model, USD per GPU-hour: spot, on-demand, 1y, 3y. For each hyperscaler with a mapped instance family (see /gpu/models hyperscaler_spot_legs), the median across regions of each term's price divided by GPUs per node, with lo/hi across regions and the discount to on-demand. Answers "what does a committed H100 cost against spot and on-demand, per cloud". Neo-cloud commitment prices are quote-only and excluded.

Input parameters:

- `gpu` (string, required): Normalized GPU model with a hyperscaler mapping, e.g. `H100 SXM`, `A100 SXM 80GB`, `L4`, `T4`. Example: H100 SXM

### `azure_eviction` (~185 tokens)

Azure eviction rates

Paid (0.01 USDC per call). Azure spot eviction-rate history (28-day buckets, sampled daily). Daily samples of the eviction-rate bucket Azure reports per SKU (`0-5`, `5-10`, `10-15`, `15-20`, `20+` percent over the trailing 28 days). Collected daily since 2026-09-05; there is no history before the first sample.

Input parameters:

- `from` (string): First sample date (inclusive), YYYY-MM-DD. Default: earliest.
- `region` (string, required): Azure region slug: `us-east`, `us-west-2` or `eu-west`.
