Live agent interface

Connect MCP

Give an AI agent direct, read-only access to verified facilities, dossiers, announcements and dataset totals. No API key or signup.

Codex

Add it once from the terminal. Codex CLI, the IDE extension and the desktop app share the same MCP configuration.

codex mcp add behind-the-watt --url https://mcp.behindthewatt.com/mcp

Then open /mcp to confirm the four tools.

Claude

Use the command for Claude Code, or add the same endpoint as a custom connector in Claude, Cowork or Claude Desktop.

claude mcp add --transport http --scope user behind-the-watt https://mcp.behindthewatt.com/mcp

Claude Code: run claude mcp list. Apps: Customize → Connectors → Add custom connector.Remote connector guide ↗

For AI agents

Start here. No scraping required.

An agent can discover the dataset, understand the evidence classes and retrieve the latest snapshot without interpreting the visual website.

Use sources[] for provenance. Treat null as unknown, never as zero. Keep announcements separate from verified operating capacity.

Evidence semantics

Three rules that prevent bad answers

Operating ≠ announced.Verified operating capacity and the third-party pipeline are separate datasets.
Null ≠ zero.Missing means unknown or still under verification.
Cite the receipt.Prefer facility sources and archived copies when making a factual claim.
