For agents · MCP

A safe publishing loop for agents.

Give Claude Code, Cursor or any MCP client an Agent key. It edits the preview, checks the result at a real URL and promotes a numbered release when the check passes. You can take any step yourself in the dashboard, including rolling back a release the agent made.

The loop

Edit, check, review, promote.

The server's help tool gives your agent this order. Production changes only at step 04, and step 05 undoes it.

  1. Edit the preview

    pagesprinter_write_file
    pagesprinter_patch_file
    pagesprinter_batch

    Writes land in the preview only. Each one returns the preview URL of the page it touched, so the agent knows where to look.

  2. Check the preview

    northwind-docs.pagesprinter.page/pricing

    The agent fetches the page or opens it in a browser tool. Previews are real HTTPS sites, so what it sees is what visitors will get.

  3. Review the changes

    pagesprinter_changes

    Lists every file added, changed or deleted since the live release. This is exactly what a promote would ship, so stray edits show up here.

  4. Promote with a message

    pagesprinter_promote

    Creates the next numbered release and waits up to 60 seconds for it to go live. The result includes the production URLs and the release to roll back to.

  5. Roll back if needed

    pagesprinter_rollback

    Points production at an earlier release. Nothing is copied, and the preview keeps the agent's work so it can fix the problem and promote again.

Setup

Connect in three steps.

  1. 1.

    In the dashboard, open API keys, create a key with the Agent preset and copy it. The secret is shown once.

  2. 2.

    Add the server to your client with one of the configurations shown here. The key goes in the Authorization header; there is nothing to install.

  3. 3.

    Ask the agent to call pagesprinter_help. It returns the loop above and lists the sites the key can reach.

Example session

One request, one release: #13.

A Claude Code session with the key ci-agent. The agent changes one price, looks at the preview, reads the diff and promotes. The release shows up in the dashboard as promoted by ci-agent via MCP.

Permissions

What an Agent key can do.

Each key carries scopes, and the server lists only the tools a key is allowed to call. No key can write production files: production changes only by promote or rollback, and each one records the key that made it.

Tools

They map one to one onto the REST API, so anything an agent does you can repeat with curl.
