## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-04.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to RoninForge/ai-price-index-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 40 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 726 tokens (~145/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 79, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `current_price` (~144 tokens)

Current price

Today's input and output price per million tokens (usd_per_mtok) for a model id, with the first-party source. Accepts short or aliased ids (e.g. "claude-opus-4-8", "gpt-4o", "gemini-2.5-pro"). Pass provider to disambiguate a bare id shared across vendors.

Input parameters:

- `model` (string, required): Model id or alias, e.g. "claude-opus-4-8" or "gpt-4o".
- `provider` (string): Optional provider slug (e.g. "openai", "anthropic") to disambiguate a bare id.

### `price_on` (~137 tokens)

Price on a date

The input and output price per million tokens that was IN EFFECT on a given date (YYYY-MM-DD), with the source that proves it. This is the point-in-time lookup: use it to value past usage or to see how a price changed over time. covered=false means the date predates the model's recorded coverage.

Input parameters:

- `date` (string, required): The date to price, as YYYY-MM-DD, e.g. "2024-01-01".
- `model` (string, required): Model id or alias, e.g. "gpt-4".
- `provider` (string): Optional provider slug to disambiguate a bare id.

### `compare` (~106 tokens)

Compare models

Side-by-side input/output prices for several model ids on one date (today by default, or pass date as YYYY-MM-DD). Each row resolves independently; unknown ids are reported per row.

Input parameters:

- `date` (string): Optional date (YYYY-MM-DD). Omit for today.
- `models` (array, required): Model ids or aliases to compare, e.g. ["claude-opus-4-8", "gpt-4o", "gemini-2.5-pro"].

### `cost_from_usage` (~164 tokens)

Cost from token usage

Value a token rollup in USD at a point in time, using the shared cache multipliers (cache read 0.1x input, cache write 1.25x for 5m / 2x for 1h). tokens accepts input, output, cache_read, cache_write_5m, cache_write_1h. Defaults to today if no date is given.

Input parameters:

- `date` (string): Optional date (YYYY-MM-DD). Omit for today.
- `model` (string, required): Model id or alias to price the usage against.
- `provider` (string): Optional provider slug to disambiguate a bare id.
- `tokens` (object, required): Token counts to value. All fields optional and non-negative; missing fields count as 0.

### `list_models` (~61 tokens)

List models

List the model ids known to the dataset, optionally filtered to one provider, each with its provider and aliases. Use this to discover valid ids for the other tools.

Input parameters:

- `provider` (string): Optional provider slug to filter by, e.g. "anthropic".
