## Quality 100/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

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

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### 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`: 5 of 5 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 916 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 5, about 916 tokens to load them all
- tool set hash: 8cf9ae9c1cb16e2a44281688a6b9407d
- badge: [![protogrid quality](https://protogrid.dev/badge/us.unfreeze/atlas.svg)](https://protogrid.dev/servers/us.unfreeze/atlas)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `about_unfrozen`: Who Gabriel Lopez is (public facts from unfreeze.us/about/), how Atlas studies are graded, how to cite the Atlas and its license, and the paid Change Check-up booking link.
- `get_answer`: Match a question about middle managers and change to the closest of the Atlas's fact-checked answer pages (deterministic keyword matching, no AI). Returns the answer text exactly as published, its graded sources and the page URL. If no page fits well, it says so and returns links to Ask the Atlas and the Atlas instead of guessing.
- `get_study`: One Atlas study record by its slug (from search_studies, e.g. "huy-2011") or its DOI: citation, design, setting, strength grade and what it means, Loop parts with verdicts, whether it is about change, Unfrozen's plain-language summary, related studies, the answer pages that cite it, and its unfreeze.us page.
- `list_loop_parts`: The parts of the Unfrozen Loop, a working model for leading change from the middle, each with a one-line description, how many Atlas studies inform it (supporting, mixed, challenging) and its unfreeze.us page.
- `search_studies`: Search the Atlas of the Middle (173 studies on middle managers and change, each with a strength grade and Unfrozen's plain-language summary). Matches words in the title, summary, setting, authors and journal. Returns each study's label, year, journal, design, grade, Loop parts, one-line summary and its unfreeze.us page. Filter by Loop part or grade.
