API and MCP server

Plug the solar installation record into your own systems and AI tools. The MCP server answers anyone in public mode; full records, the REST API, the change feed and webhooks come with Enterprise.

MCP server (AI tools)

Connect PanelCensus to Claude, ChatGPT or your own agent. The server is https://panelcensus.com/api/mcp (Streamable HTTP). Without a key it answers in public mode: summaries with a link to each record, 5 results per call. With an Enterprise key it returns full records, change history and the change feed.
