## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_dependencies`

- 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
Check a dependency manifest (package.json, requirements.txt, pyproject.toml or Pipfile) for third-party API SDKs that are major versions behind, deprecated or replaced, against the live npm registry and PyPI. Returns each SDK's current spec, latest version, release-notes link and a Versyka migration guide when one exists.
```

## Only reads (6)

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

### `find_retired_models`

- The name "find_retired_models" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Scan source and config files for AI model IDs that the vendor (OpenAI, Anthropic, Google Gemini, Mistral, Cohere) or hosting platform (Amazon Bedrock, Groq) has retired or scheduled for retirement. Exact matches only, including Bedrock, Vertex AI, LiteLLM and OpenRouter spellings. Returns each model's shutdown date, days left, the vendor's recommended replacement, the source page and the file:line locations.
```

### `get_migration_guide`

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

Description, as the server wrote it:

```untrusted-server-text
One migration guide as Markdown: what changed, each step with before and after code, how to find every affected call, how to test, and the vendor sources it is based on.
```

### `get_sdk_versions`

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

Description, as the server wrote it:

```untrusted-server-text
The latest version of an npm or PyPI package, whether it is deprecated, its release-notes link, the API vendor it belongs to and a Versyka migration guide when one exists.
```

### `list_migration_guides`

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

Description, as the server wrote it:

```untrusted-server-text
Versyka's step-by-step SDK migration guides (OpenAI, Anthropic, Google Gemini, AWS, Stripe, Firebase, Slack, Twilio, Auth0, Pinecone), optionally filtered by package name.
```

### `list_model_retirements`

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

Description, as the server wrote it:

```untrusted-server-text
The AI model retirement calendar: model IDs with their shutdown dates, replacements and sources, soonest first. Filter by vendor or by how many days ahead to look.
```

### `lookup_model`

- The name "lookup_model" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Is this AI model ID retired or scheduled for retirement? Accepts plain IDs and gateway spellings (e.g. openai/gpt-4-0613, anthropic.claude-3-sonnet-20240229-v1:0, claude-3-opus@20240229). Returns the shutdown date, status, replacement and source, or that no retirement is listed.
```
