Add Cemented to Claude

You need a paid Claude plan. Your organization may control which plugins you can install.

1. Download the plugin ZIP. In Claude, open Customize → Plugins and upload the custom plugin file.
2. Open the installed Cemented plugin → Connectors. Click Connect beside cemented and finish signing in to Cemented.
3. Start a new chat and enable Cemented under + → Connectors. Ask for research or a document audit.

Uploading the plugin does not sign you in. Complete the Connect step even if Claude does not prompt you in chat.

Extract the ZIP, then start Claude Code with the extracted cemented directory. Complete the Cemented connection through /mcp.

claude --plugin-dir /absolute/path/to/cemented

For a manual installation, download a fresh ZIP and update your installed plugin. Your account connection is managed separately from the plugin files.

For ChatGPT, follow the custom MCP connection guide. For agents that load local skills, use the portable bundle. Uploading this ZIP as a chat attachment does not install it in ChatGPT.
