About

StemLab — timing and loops for Shorts is an MCP server published by kieransimkin. Marketplaces we read that list it: 1 (Official MCP Registry). The last change we recorded was on 2026-10-12. As of our marketplace pass on 2026-10-13.

What it asks for

  • Runs on your machine
  • Settings: 1

Requires: STEMLAB_CODEX_WORKSPACE

What it declares, asks for and runs, in full

Only install plugins from developers you trust. We list what marketplaces publish and do not test plugins.

Package

PyPI danceflow-stemlab (danceflow-stemlab on PyPI)

  • PyPI downloads/week: 798 (2026-10-13)
  • PyPI downloads/month: 781 (2026-10-13)
  • Latest version on PyPI: 1.4.1, published 2026-10-11

No known vulnerabilities in OSV for 1.4.1 (checked 2026-10-13)

PyPI facts come from pypi.org, PyPI downloads from pypistats.org. Each figure is the registry's own and is never added to another. A registry that publishes no figure shows none: no number is not zero. Vulnerability records come from OSV.dev (CC BY 4.0) and concern the declared version only; a listing that declares no version gets no answer. We do not scan code.

Works with

  • Claude Code
  • Codex
  • Cursor
  • VS Code
  • Copilot CLI

From the marketplaces that list it and the MCP transport it declares, as each client documents them. We do not test plugins.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.

Is this your plugin?

Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
