MCP server · by opensysml.org
About
OpenSysML MCP server is an MCP server published by opensysml.org. Marketplaces we read that list it: 1 (Official MCP Registry). The last change we recorded was on 2026-11-08. As of our marketplace pass on 2026-11-08.
What it asks for
- Runs on your machine
None of the marketplaces we read publishes its tools or the settings it asks for.
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 @openmbee/sysml-mcp (@openmbee/sysml-mcp on npm)
- npm downloads/week: 263 (2026-11-06)
- npm downloads/month: 648 (2026-11-06)
- Latest version on npm: 0.12.0, published 2026-11-04
- Declared version 0.12.1 is not listed on npm
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.
Works with
- Claude Code
- Codex
- Cursor
- VS Code
- Copilot CLI
A one-click link opens the client, which asks you to confirm before it adds the server.
From the marketplaces that list it and the MCP transport it declares, as each client documents them. We do not test plugins.
Connect
Commands and configs built only from what its marketplaces declare. We do not run them for you and do not test plugins.
As a local MCP server: npm package
Built from what Official MCP Registry declares.
claude mcp add --transport stdio sysml-mcp -- npx -y @openmbee/sysml-mcp -root .[mcp_servers.sysml-mcp]
command = "npx"
args = ["-y", "@openmbee/sysml-mcp", "-root", "."]{
"mcpServers": {
"sysml-mcp": {
"command": "npx",
"args": [
"-y",
"@openmbee/sysml-mcp",
"-root",
"."
]
}
}

Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

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.
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.
