## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__data-exchange__query_us_federal_register` `mcp__data-exchange__request_paid_access` `mcp__data-exchange__sample_us_federal_register` `mcp__data-exchange__search_public_datasets` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (6)

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

### `aggregate_imported_dataset`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this paid read-only tool for deterministic grouped statistics instead of downloading rows and calculating locally. Returns bounded count, sum, average, minimum, or maximum groups with dataset provenance.
```

### `request_capability`

- The name "request_capability" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Use this state-changing tool only when existing discovery and coverage tools cannot satisfy the task. Records demand for a missing dataset, aggregation, insight, filter, freshness level, or export; repeated requests increase autonomous build priority.
```

### `request_dataset_materialization`

- The name "request_dataset_materialization" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Queue a discovered official dataset for prioritized detached ingestion. This free idempotent operation returns a durable job ID; poll get_materialization_status until it supplies sample and query URLs.
```

### `request_paid_access`

- The name "request_paid_access" says "request": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this state-changing tool only after free samples demonstrate value and the human owner approves payment. Creates a Stripe Checkout plus one-time claim URL; choose the $5 pass for research or $5/month subscription for recurring workflows.
```

### `sample_imported_dataset`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this free tool to evaluate a query-ready official dataset before paying. Returns three normalized rows, deterministic summaries, freshness, and provenance; use query_imported_dataset only after the sample proves useful.
```

### `sample_us_federal_register`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this free no-auth tool for current US regulatory activity or to evaluate AgentNative before paying. Returns three Federal Register records plus deterministic aggregates over the latest 25 documents, direct record URLs, provenance, and rate-limit status.
```

## Only reads (8)

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

### `get_coverage_status`

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

Description, as the server wrote it:

```untrusted-server-text
Use this free operational tool to decide whether available public-data coverage is sufficient or whether to request a missing capability. Returns discovery, materialization, queryable-row, queue, failure, and freshness counts.
```

### `get_materialization_status`

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

Description, as the server wrote it:

```untrusted-server-text
Poll a durable materialization job. A complete result includes the query-ready dataset ID plus free sample and paid query URLs.
```

### `list_imported_datasets`

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

Description, as the server wrote it:

```untrusted-server-text
Use this free tool when an agent needs only datasets that can be sampled or queried now. Returns fully published warehouse snapshots with dataset IDs, row counts, freshness, and provenance.
```

### `list_official_sources`

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

Description, as the server wrote it:

```untrusted-server-text
Use this free tool to inspect which federal, state, city, police, education, and other official source scopes AgentNative currently covers. Returns each source's importer, discovery state, and materialized coverage; it does not return dataset rows.
```

### `query_imported_dataset`

- The name "query_imported_dataset" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this paid read-only tool after sample_imported_dataset confirms the data is suitable. Returns up to 100 normalized rows from a published snapshot with bounded pagination, one exact-match filter, freshness, and provenance.
```

### `query_us_federal_register`

- The name "query_us_federal_register" says "query": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this paid read-only tool when the free Federal Register briefing is insufficient. Returns up to 100 normalized official records filtered by date or document type, with deterministic provenance and direct source URLs.
```

### `search_discovered_datasets`

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

Description, as the server wrote it:

```untrusted-server-text
Use this free tool to find datasets across all discovered official sources, including candidates not yet queryable. Returns catalog matches and materialization state; use list_imported_datasets when only query-ready data is acceptable.
```

### `search_public_datasets`

- The name "search_public_datasets" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use this free tool first when an agent needs official US federal data but does not yet know the dataset ID. Searches normalized catalog metadata and returns matching datasets with provenance; it does not query dataset rows.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 6 tools that change things (6 write). Whether a call also works without credentials was not tested: tools are never called.

https://agentnative.cazimedia.com/mcp: tools/list returned 14 tools to an anonymous client, including request_dataset_materialization (write), sample_imported_dataset (write), sample_us_federal_register (write), aggregate_imported_dataset (write), request_capability (write) and 1 more
