## 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 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-datos-ar).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 4 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 502 tokens (~251/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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.

## MCP tools (2)

### `search_series` (~183 tokens)

Search Argentina's national time-series catalog (apis.datos.gob.ar) for series matching a keyword. Titles/descriptions are in Spanish (e.g. q="inflacion", "pbi", "emae", "tipo de cambio", "desempleo"). Returns matching series with their ids (use these with get_series), titles, units, frequency, date coverage, dataset and source.

Input parameters:

- `dataset_theme` (string): Optional theme id filter, e.g. "actividad", "precios".
- `limit` (number): Max results to return (default 10).
- `offset` (number): Result offset for pagination (default 0).
- `q` (string, required): Search keyword in Spanish, e.g. "inflacion", "pbi", "tipo de cambio".
- `units` (string): Optional units filter, e.g. "Porcentaje".

### `get_series` (~266 tokens)

Fetch observations for one or more Argentine time series by id (ids come from search_series). Data is official Argentine statistics; titles are in Spanish. Pass multiple comma-separated ids to align several series on the same dates. Use collapse to resample (e.g. monthly→yearly avg) and representation_mode to transform values (e.g. percent change vs a year ago). Returns rows of [date, value, ...] plus metadata.

Input parameters:

- `collapse` (string): Resample frequency, e.g. "year" to roll monthly data up to yearly.
- `collapse_aggregation` (string): How to aggregate when collapsing (default avg).
- `end_date` (string): Latest date, ISO YYYY-MM-DD (optional).
- `ids` (string, required): One series id, or several comma-separated, e.g. "143.3_NO_PR_2004_A_21". From search_series.
- `limit` (number): Max rows to return (default 100, API max 1000).
- `metadata` (string): Metadata detail level (default simple).
- `representation_mode` (string): Value transform: raw value (default), period change, or change vs a year ago.
- `start_date` (string): Earliest date, ISO YYYY-MM-DD (optional).
