AI assistants can make mistakes in numbers, formulas and claims. Energent gives your assistant a second opinion. When you connect Energent, you can ask Claude, ChatGPT or Codex to send its work to Energent for an independent audit.

An Energent auditor checks the work against your source files. Then it writes a report that shows what is correct, what is wrong and what to fix. You read the result in the same chat, and you can also open the audit in the Energent web app.

What you can ask

After you connect Energent, ask your assistant in your own words. For example:

"Audit this financial model against the bank statements I attached."
"Use Energent to check the numbers in this report before I send it."
"Ask Energent to verify that this summary matches the contract."
"I fixed the errors. Ask Energent to check it again."

The assistant sends the work and the source files to Energent, waits for the audit, and shows you the findings. If the auditor has a question, the assistant asks you, or you can answer in the Energent web app.

What you need

An Energent.ai account.
Credits on your Energent plan. An audit uses the same credits and file uploads as an audit in the Energent web app.

Connect Energent

Each app asks you to sign in to Energent one time. Then Energent shows the name of the app and asks for your approval. Select Allow to connect.

Claude

In Claude, open Settings > Connectors.
Add a custom connector. Type Energent as the name and https://mcp.energent.ai/mcp as the URL.
Select Connect. Sign in to Energent and select Allow.

ChatGPT

In ChatGPT settings, turn on developer mode.
Add a new app with the URL https://mcp.energent.ai/mcp.
Sign in to Energent and select Allow.

Claude Code

In a terminal, run:

claude mcp add --transport http energent https://mcp.energent.ai/mcp

In Claude Code, type /mcp, select energent, and sign in.

Open the sign-in page on the same computer that runs Claude Code.

Codex

In a terminal, run:

codex mcp add energent --url https://mcp.energent.ai/mcp

If the sign-in page does not open, run codex mcp login energent.

Other apps

Any app that supports remote MCP servers with sign-in can use the address https://mcp.energent.ai/mcp. If your app cannot connect, send an email to support@energent.ai.

Good to know

Attach your files. Energent checks the files that your assistant sends. It does not open links.
File size. Each file can be up to 1 GB.
Number of audits. Your plan sets how many audits can run at the same time. After an audit stops, it can take up to 10 minutes before you can start the next one.
Credits. If you run out of credits, your assistant shows a link where you can add more.

Your data and privacy

Each audit is saved in your Energent account, the same as an audit that you start in the web app.
A connected app can only see the audits that it started. It cannot see your other Energent conversations.
Audits from connected apps do not use your email or Slack integrations.
To disconnect an app, sign in to app.energent.ai and open Settings > Connected apps. The app loses access within 1 minute.

For more information, read the Privacy Policy and the Terms and Conditions.

Troubleshooting

The sign-in page keeps opening. Make sure that you sign in with the correct Energent account. To change the account, select Use a different account on the approval screen.

After you select Allow, the page does not load (Claude Code or Codex). The browser must be on the same computer as Claude Code or Codex. If you work on a remote computer over SSH, open the sign-in link on that computer, or forward the sign-in port.

"Too many Energent sessions are running". Wait for the current audit to finish, or ask your assistant to stop it. Then try again after a few minutes.

An error about credits or file uploads. Open the link in the message to add credits or change your plan.
