About
Koma Gate MCP is an MCP server published by swnotmetal. Marketplaces we read that list it: 1 (Official MCP Registry). The last change we recorded was on 2026-10-14. As of our marketplace pass on 2026-10-17.
What it asks for
- Runs on your machine
- Secrets: 4
- Settings: 6
Requires: ANTHROPIC_API_KEY (secret), DEEPSEEK_API_KEY (secret), GEMINI_API_KEY (secret), OPENAI_API_KEY (secret)
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
npm koma-gate-mcp (koma-gate-mcp on npm)
- npm downloads/week: 27 (2026-10-13)
- npm downloads/month: 143 (2026-10-13)
- Latest version on npm: 0.1.2, published 2026-08-18
No known vulnerabilities in OSV for 0.1.1 (checked 2026-10-14)
npm facts come from the public npm registry (registry.npmjs.org, api.npmjs.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.

Want this mark on your plugin in our catalog?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works
You also 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.
