Connect an Agent with MCP

Editor MCP lets an external AI agent control the paywall currently open in your browser. Use it when you want to keep working in Claude Code, Codex, Cursor, or another MCP-compatible agent while giving that agent live access to the editor.

Connect an agent

1. Open the paywall you want the agent to edit.
2. Open AI Chat in the editor sidebar.
3. Click the agent connection pill.
4. Choose Skill or MCP.
5. Copy the install command shown in the editor.
6. Paste the pairing prompt into your agent.

If you choose Skill, the editor shows:

npx skills add superwall/skills

Then paste the generated prompt into your agent:

Connect to the Superwall editor using the skill with pairing code: XXXX-XXXX-XXXX

If you choose MCP, select your client first. The editor generates the right command or configuration for Claude Code, Codex, Cursor, or another MCP client. Use the command shown in the editor because it includes the correct Editor MCP URL for your environment.

The MCP prompt looks like this:

Connect to the superwall-editor MCP with pairing code: XXXX-XXXX-XXXX

Connected state

After the agent attaches, the connection pill shows the connected client and tool activity.

For example, this is what it looks like when an agent uses the pairing code to connect to the editor:

After the connection completes, the editor shows the attached client and recent tool activity.

The editor keeps the browser session open while the page is open. From the connection panel you can:

• Disconnect Agent: Release the current agent while keeping the editor session available for another pairing.
• End Session: Close the browser editor session and invalidate the pairing code.

Only one external controller can be attached to an editor session at a time. Disconnect the current agent before attaching a different one.

What agents can do

Attached agents receive the editor's live tool list. The exact list can change as the editor evolves, but today agents can:

• Inspect and edit the paywall: Agents can read the current paywall, selected elements, children, navigation pages, computed styles, and screenshots. They can then update text, styles, names, node order, hierarchy, or write native paywall HTML directly into the editor.
• Work with content and resources: Agents can upload image and video assets, create and edit products, manage style tokens, and update variables, variable values, and dynamic values. They can also add localization languages, run AI localization, and configure trial-started notifications.
• Configure behavior and advanced flows: Agents can add or clear tap behaviors such as purchase, restore, close, open URL, set state, select product, navigate page, request permission, request callback, scroll, focus input, delay, animation, and haptics. They can also edit routes, transitions, branches, advanced native elements, and use search or find/replace to make broader changes.

Session limits

Editor MCP uses pairing codes and session tokens rather than your account-level MCP OAuth flow.

If a pairing code expires, open the connection panel again and use the new code.

Troubleshooting

The agent cannot attach

Check that the paywall editor tab is still open, the pairing code has not expired, and the agent is using the prompt from the current connection panel.

The session says another controller is connected

Only one controller can be attached. Click Disconnect Agent, then attach the new agent with the latest pairing code.

Tool calls fail after a browser refresh

Wait a moment for the editor to reconnect. If calls still fail, end the session and create a new connection from the editor.

The agent edited the wrong thing

Use the editor's undo and history tools to review or roll back changes. Select the exact element you want changed before sending the next prompt so the agent receives that selection as context.
