## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 743 tokens (~148/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-02 (score 71, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `search_studies` (~231 tokens)

Search Atlas 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.

Input parameters:

- `grade` (string): Only studies with this evidence-strength grade. No study is currently rated high.
- `limit` (integer): How many studies to return (1 to 20, default 8).
- `part` (string): Only studies that inform this part of the Unfrozen Loop: P1 Surface both ways; P2 Make sense together, top included; P3 Start it close to the work; P4 Review on a rhythm, then hold the pace; P6 The m…
- `query` (string, required): Keywords or a short question, for example "bad news upward", "Nokia", "Huy 2011" or "sensemaking during restructuring".

### `get_study` (~142 tokens)

Get one Atlas 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.

Input parameters:

- `doi` (string): The study's DOI, with or without https://doi.org/, for example "10.1002/smj.1124".
- `slug` (string): The study's Atlas slug, for example "vuori-and-huy-2016".

### `get_answer` (~99 tokens)

Get a fact-checked Atlas 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.

Input parameters:

- `question` (string, required): The question in plain words, for example "Why do middle managers resist change?"

### `list_loop_parts` (~56 tokens)

List the Unfrozen 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.

### `about_unfrozen` (~48 tokens)

About Unfrozen and the Atlas

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.

## Diagnostics

## Common questions

### What is the Unfrozen Atlas of the Middle MCP server?

Unfrozen Atlas of the Middle is an MCP server listed in the public MCP registry as us.unfreeze/atlas. Graded research on middle managers and change: search studies, get fact-checked answers. This page covers its hosted endpoint (https://unfreeze.us/mcp).

### Is the Unfrozen Atlas of the Middle MCP server safe to use?

Unfrozen Atlas of the Middle scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Unfrozen Atlas of the Middle MCP server expose?

Unfrozen Atlas of the Middle exposes 5 tools: search_studies, get_study, get_answer, list_loop_parts, about_unfrozen. Their descriptions and schemas cost roughly 576 tokens of context every time the server is loaded.

### Does the Unfrozen Atlas of the Middle MCP server require authentication?

No. We connected to Unfrozen Atlas of the Middle without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Unfrozen Atlas of the Middle MCP server still maintained?

Unfrozen Atlas of the Middle is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Unfrozen Atlas of the Middle MCP server?

VerifyMCP ran 13 checks on Unfrozen Atlas of the Middle, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
