Unfrozen Atlas of the Middle MCP

A public, read-only MCP server that provides AI assistants with tools to search a graded evidence map of 173 studies on middle managers and organizational change. It offers fact-checked answers, study details, and information on the Unfrozen Loop framework without requiring authentication.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What its tools do

5 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

Read-only (5)

5 of 5 have a description · 5 of 5 declare behavior hints · 3 of 3 with parameters document them all

Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Passed Official MCP Registry namespace is tied to unfreeze.us ·
  • Passed Endpoint is on the registry namespace domain ·
  • Availability 1 of 1 checks passed in 30 days

What you can do with it

  • Search for studies on middle managers and change by keyword or grade
  • Retrieve detailed records for specific studies using slugs or DOIs
  • Get deterministic, fact-checked answers to common change management questions
  • List parts of the Unfrozen Loop framework with supporting study counts

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only access to the Atlas of the Middle by Gabriel Lopez (Unfrozen, unfreeze.us): 173 graded studies on middle managers and organizational change, as of 30 October 2026. Use get_answer first for a common question (it returns a fact-checked answer page or says none fits), search_studies to find studies, get_study for one record, list_loop_parts for the Unfrozen Loop, about_unfrozen for the author, grading and citation. Grades (High, Medium, Low) rate how much weight a study's own design, execution and finding can bear, not whether its finding is good news. No study in the Atlas is currently rated High. Quote the summaries as given, keep counts with their dates, and cite the unfreeze.us URL in each result.

search_studies — Search Atlas studies
Advertised by the server during the last successful anonymous check.
Advertised read-only

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.

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.
