ForceField Silicon plugins

The plugin marketplace for MDEngine, the molecular-dynamics workbench from ForceField Silicon (Gitinama Inc.).

Install in Claude Code

claude plugin marketplace add forcefieldsilicon/mdengine-plugins
claude plugin install mdengine@forcefieldsilicon

Already installed? claude plugin update mdengine@forcefieldsilicon brings in the current release (eight skills, two connectors), then restart Claude Code.

Use in claude.ai and the Claude desktop app

Since November 2026 plugins, skills and connectors share one Plugins page in Settings (it replaced the separate Skills, Connectors and Plugins tabs; accounts still on the old layout find the same controls under Settings > Connectors and Settings > Skills).

1. Add the hosted server as a connector. Choose a remote (custom) connector, name it mdengine-cloud and set the server URL to https://api.forcefieldsilicon.com/mcp. Under Advanced settings, pick the Streamable HTTP transport. Sign in with the key from a credit pack when the first tool call asks.
2. Add the skills. Choose to import skills from GitHub, enter forcefieldsilicon/mdengine-plugins and select the eight skills: mdengine, lammps-deck, potentials, results, mineral-processing-campaign, alloy-wear-study, dark-proteins-study and forcefield-studies.
3. skills/ at the repo root mirrors plugins/mdengine/skills/, kept identical by scripts/sync_skills.sh --check. The GitHub import reads the root layout.

Team and Enterprise admins: plugins in the Claude desktop app need Skills turned on for the organization (Organization settings > Library > Policy) from November 30, 2026.

Plugins

Plugin	What it gives an agent
mdengine	The hosted MDEngine MCP server, the studies connector, and eight skills: check a deck, run LAMMPS or OpenMM on a GPU, watch the job, pull the results, and read them.

Credits and API keys

The hosted tools need an API key. A key comes with a prepaid credit pack from forcefieldsilicon.com/mdengine. Sign in when your client asks and paste the key once on the consent page. The key stays with you.

Privacy

The plugin's connectors send one extra request header, X-MDE-Source: claude-code-plugin, so we can count how many connections come through the plugin rather than a hand-typed server entry. Nothing else about you or your machine is added. What the hosted service receives and keeps is in the privacy policy.

Licensing
