## 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 2026-08-03.

- **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**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 64 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 556 tokens (~278/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**: 27/100
  - Stability observed for 8 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.

## MCP tools (2)

### `list_presets` (~60 tokens)

List the built-in time-series presets (realistic ready-made configurations like e-commerce sales, server CPU, IoT temperature, website traffic, stock price, API latency). Use a preset name with generate_timeseries to get sensible defaults you can still override.

### `generate_timeseries` (~496 tokens)

Generate realistic synthetic time-series data with configurable trend, seasonality, noise, anomalies, and multiple correlated series. Ideal for testing dashboards, charts, monitoring/alerting, forecasting and anomaly-detection. Output as JSON, CSV, or SQL INSERTs. Use a preset for quick sensible defaults, or specify components explicitly.

Input parameters:

- `anomalies` (array): Injected anomalies for testing detection/alerting. Pro feature.
- `ar1_phi` (number): AR(1) autocorrelation coefficient (-1..1), used when noise='ar1'.
- `baseline` (number): Baseline level the series varies around.
- `correlation` (number): Target pairwise correlation between multiple series (0..1). Pro feature.
- `format` (string): Output format. 'json' (default), 'csv', or 'sql'. CSV and SQL are Pro features.
- `frequency` (string): Spacing between points. Default daily (or the preset's frequency).
- `integer` (boolean): Round values to integers.
- `length` (integer): Number of data points. Default 100.
- `max` (number): Clamp values to this maximum.
- `min` (number): Clamp values to this minimum.
- `names` (array): Optional explicit series names.
- `noise` (string): Noise model. 'ar1' (autocorrelated) is a Pro feature.
- `noise_level` (number): Standard deviation of the noise. Default 1.
- `preset` (string): Optional preset name (see list_presets). Fills sensible defaults; explicit params below override it.
- `seasonality` (array): One or more seasonal cycles, summed together. Multiple cycles are a Pro feature.
- `seed` (integer): Deterministic seed for reproducible output. Pro feature.
- `series_count` (integer): How many series to generate. >1 is a Pro feature. Default 1.
- `start` (string): ISO start timestamp, e.g. '2024-01-01T00:00:00Z'. Default 2024-01-01.
- `table_name` (string): Table name for SQL output. Default 'timeseries'.
- `trend` (string): Trend shape. Non-linear trends are a Pro feature.
- `trend_strength` (number): Trend magnitude: slope per point (linear), growth rate (exponential), or capacity (logistic).
