### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,262 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 4 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 7, about 1,262 tokens to load them all

### Tool changes

- 2026-10-19 `list_model_retirements` changed (inputSchema)
- 2026-10-19 `find_retired_models` changed (description)
  - before: Scan source and config files for AI model IDs that the vendor (OpenAI, Anthropic, Google Gemini, Mistral, Cohere) 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.
  - after: 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.

## Tools (7)

- `check_dependencies`: 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.
- `find_retired_models`: 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`: 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 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`: 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 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`: 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.
