Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put OpenEI to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

OpenEI works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put OpenEI to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of OpenEI, so you can see the experience inside your AI.

It does not authenticate your account with OpenEI. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work OpenEI owners hand off.

This MCP is built for professionals in the energy and solar sectors who need to move from raw data to actionable models quickly.

  • 01

    Solar Installers

    They hand off customer addresses to the AI to generate instant rate quotes and ROI proposals.

  • 02

    Energy Consultants

    They use the AI to pull complex tariff structures for detailed energy cost modeling.

  • 03

    Facility Managers

    They ask the AI to compare rates across different locations for site selection and budgeting.

FAQ

Questions OpenEI owners ask.

  • 01

    Where does this electricity rate data come from?

    The data is sourced from the National Utility Rate Database, which is maintained by the US Department of Energy.

  • 02

    Can I get rates for a specific address?

    Yes. You can provide a street address, and the MCP will geocode it to find the serving utility and its rates.

  • 03

    Does this include commercial and industrial rates?

    Yes. The MCP provides specific capabilities to query residential, commercial, and industrial sectors separately.

  • 04

    What kind of rate details can my AI retrieve?

    Your AI can pull energy charges, demand charges, fixed charges, seasonal variations, and time-of-use periods.

  • 05

    Which AI clients can I use with this MCP?

    You can use this with any MCP-compatible client, including Claude, Cursor, and Windsurf.

  • 06

    How do I find electricity rates for my address?

    Use the get_rates_by_address capability with your full street address. The API will geocode your location and return all applicable utility rates (residential, commercial, industrial). For example, enter '1617 Cole Blvd, Golden, CO 80401' to see rates from Xcel Energy and other providers serving that area.

  • 07

    What's the difference between residential, commercial, and industrial rates?

    Residential rates (sector 1) are for homes and typically have simple tiered or time-of-use structures. Commercial rates (sector 2) serve businesses and include general service and large power tariffs with demand charges. Industrial rates (sector 3) are for heavy manufacturing with the lowest per-kWh costs but complex demand and power factor adjustments. Use the specific sector capabilities or filter with the sector parameter.

  • 08

    Can I get complete rate structures with time-of-use details?

    Yes. Set the detail parameter to 'full' when calling get_utility_rates or get_rate_detail. This returns the complete tariff structure including energyratestructure (time-of-use periods and seasonal blocks), demandratestructure, fixed charges, minimum charges, and tax adjustments. Essential for accurate solar ROI calculations and detailed energy cost modeling.
