McBrain plugin — v5.0.0
A ready-to-install ZIP of the McBrain plugin, for environments where adding a plugin marketplace via the /plugin slash command is blocked (e.g. by IT policy). Upload mcbrain-v5.0.0.zip directly instead.
What's in the zip
The archive is the plugin root — .claude-plugin/plugin.json, skills/, commands/, and .mcp.json sit at the top level (no wrapper folder), which is what the plugin loader expects. Includes all four skills: mcbrain, mcbrain-setup, local-research-runner, local-research-db.
Install from the ZIP
Download mcbrain-v5.0.0.zip from this release, then either:
- Upload via the plugin UI — use your client's "upload a ZIP" option and select the file as-is (do not re-zip or unzip-and-rezip — that re-introduces a wrapper folder).
- Local dir flag (Claude Code v2.1.128+):
claude --plugin-dir ./mcbrain-v5.0.0.zip - Hosted URL (loads for one session):
claude --plugin-url https://github.com/jbdamask/mcbrain/releases/download/v5.0.0/mcbrain-v5.0.0.zip
After install, run /reload-plugins and check /help for the mcbrain:* skills.
Notes
- Plugin and marketplace manifests are both pinned to
5.0.0. - If your client allows it, the marketplace route still works:
/plugin marketplace add jbdamask/mcbrainthen/plugin install mcbrain@mcbrain.
