## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_identifiers`

- 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
Look up many identifiers at once before shipping code: model ids, API endpoints (/v1/assistants), MCP tool names, SDK methods or field names. For each one, a one line answer and the ids of matching records, plus the records themselves. A record scoped to some code (for example only repos that depend on a given SDK major version) is returned with that scope spelled out, never as an unconditional hit. Max 100 identifiers.
```

### `check_model`

- 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
Look up one AI model id (for example gpt-4o-2024-05-13 or claude-sonnet-4-5) in apiwatch's reviewed feed of vendor changes before you use it in code. Returns a one line answer (when it stops working, changes behavior, or its deprecation key date) and each matching record with the date, what to do and the replacement, and links to the record and the vendor's source. "No record" means apiwatch has no record for it, not that it is safe. Records that apply only in some repos or files say so in scope.
```

## Only reads (3)

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

### `get_record`

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

Description, as the server wrote it:

```untrusted-server-text
Get one apiwatch record in full, as published: what changes, what to do, the strings to search for, ids it does not cover, where it applies, the vendor source and when it was reviewed. Use an id from another tool's result.
```

### `list_upcoming`

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

Description, as the server wrote it:

```untrusted-server-text
List the dated changes in apiwatch's feed from today forward, soonest first: model retirements, breaking API changes, silent behavior changes and deprecation key dates. Use it to plan migrations. Optionally limit to the next N days (default 90, max 365) or one vendor. Max 50 records.
```

### `search_changes`

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

Description, as the server wrote it:

```untrusted-server-text
Search apiwatch's feed of reviewed vendor changes by text: a case-insensitive match on each record's summary, vendor and signatures (the strings to look for in code). Use it when you know a product or feature name but not the exact id. Newest key date first; default 20 results, max 50.
```

## Claude Code permissions
