## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_monitor`

- The name "delete_monitor" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `answer`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The flagship: ask a natural-language question about the served official statistics. Returns a COMPUTED answer (real Python runs in a sandbox over the verified store, nothing is estimated by a model), the Plotly chart, the Python code, citations to the official tables, and a verification badge per series. CROSS-SOURCE: one question may join series from DIFFERENT agencies, e.g. unemployment from the US BLS, Statistics Canada and the UK ONS in a single call, for correlations, ratios, and like-for-like comparison. How many series one question may join is set by the caller's plan; asking for more returns a series_limit error naming that cap. Returns a refusal when no served series can answer. Takes 10-40 seconds. Requires a free API key (create at /account on the Starwell host; pass Authorization: Bearer dlk_... or set STARWELL_API_KEY on the starwell-mcp bridge). Keyless calls return key_required.
```

### `create_monitor`

- The name "create_monitor" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a monitor: when the store's refresh lands a new period or a revised value for the series, a series.updated webhook fires to your URL with the new value, verification status, and citation. Requires an API key (free with an account at /account); webhook must be https. Manage with list_monitors / delete_monitor.
```

### `deep_analysis`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The moat: a PLANNED multi-section report on a question. The engine designs 3-4 orthogonal analyses (trend, statistics, outliers, cross-series relationships), runs real Python for each in the sandbox over the verified store, and synthesizes one decision-ready report. Every number computed, every series cited and verification-badged. Sections can join series from DIFFERENT agencies in one report, up to the caller's plan width; over it, the call returns a series_limit error naming that cap. Slower than answer (60-180 seconds), so use it for "analyze", "break down", "give me a full picture" asks; use the answer tool for a single direct question. Requires a free API key (create at /account on the Starwell host; pass Authorization: Bearer dlk_... or set STARWELL_API_KEY on the starwell-mcp bridge). Keyless calls return key_required.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `get_observations`

- The name "get_observations" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Observation values for one series. Every value carries provenance (the exact source URL it came from, retrieval time, connector version) and the envelope carries the series verification status + citation. Defaults to the latest 60 points; use start/end (YYYY-MM-DD) or latest to control the window. Pass asOf for a point-in-time read: the values as Starwell's store held them on that date, before any later revision (available from the series' first ingest forward).
```

### `get_series`

- The name "get_series" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full metadata for one series: indicator, unit, frequency, geography, coverage, its VERIFICATION STATUS (passing/stale/failing/unverified from golden-value + freshness checks against the live source), recent check records, and the citation to the official table.
```

### `get_series_stats`

- The name "get_series_stats" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Latest value, previous, all-time min/max, mean, and change vs the previous period and vs a year ago — computed over the verified store, with the citation attached. The cheap way to answer "what is it now and how has it moved" without a full analysis run.
```

### `list_datasets`

- The name "list_datasets" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the datasets (official releases/tables) available in one source, with coverage dates and links to the official table pages.
```

### `list_monitors`

- The name "list_monitors" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Monitors on your API key, with delivery health (last fired, failures, active).
```

### `list_sources`

- The name "list_sources" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the official statistical sources served by this data layer (e.g. Statistics Canada, FRED), with dataset/series counts, cadence notes, and terms links. Start here to see what exists.
```

### `search_catalog`

- The name "search_catalog" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find series across ALL sources in one call: case-insensitive search over series ids, indicator names, geographies, and dataset titles (e.g. "unemployment canada", "10-year treasury", "CPI"). Returns candidate series with units, coverage, verification status, and license, plus datasetMatches from the wider dataset index — datasets whose series can be requested by source-native id and are fetched from the official source on first call. The fastest path from a question to the exact series id to fetch or pin in the answer tool.
```
