@Sites Plugin

Portable Agent Plugin package for the BRAINK × KEX Sites control plane.

The package follows the current Agent Plugins structure: plugin.json, mcp.json, and skills/sites/SKILL.md. The MCP server is server/mcp_server.py.

sites_list, site_get, site_create, domain_bind, version_create, deploy, public_readback, ledger_verify, estate_import.

Local MCP

pip install -r server/requirements.txt
python server/mcp_server.py

The checked-in mcp.json points at http://127.0.0.1:8000/mcp for local/desktop development. ChatGPT web requires a registered reachable HTTPS MCP endpoint (or supported secure tunnel) before @Sites can become an installed callable plugin in that web environment. Do not replace the URL with a guessed public endpoint.

Once the server has a real HTTPS endpoint, replace only mcpServers.sites.url with that endpoint, register it in ChatGPT Developer Mode, then bind the resulting app ID to the plugin package. Site identity and execution semantics remain unchanged.
