MCP server

Let Claude, Cursor, or any MCP-compatible tool read and write your paywall configurations.

Experiwall ships an MCP (Model Context Protocol) server so AI agents can list paywalls, read their configs, create variants, and publish new versions, all through structured tool calls.

Configure your client

  "mcpServers": {
    "experiwall": {

      "headers": { "x-api-key": "ew_sec_xxxxxxxx" }
    }
  }
}

Tip

Pair the MCP server with the visual editor: ask Claude to draft a paywall, then open it in the studio to polish the design.

Claude.ai and Claude Desktop

If your account has access to Anthropic's Request headers beta for custom connectors, you can add Experiwall straight from Claude's UI, no CLI required.

  1. In Claude, go to Settings → Connectors → Add custom connector.
  2. Enter the MCP server URL: https://www.experiwall.com/api/mcp.
  3. Open Request headers, add x-api-key, and paste your secret key as the value.

Gated beta

Request headers for custom connectors is an Anthropic beta rolling out gradually. If your Add custom connector dialog only shows OAuth Client ID and Secret, with no Request headers section, you do not have access yet. ChatGPT's Developer Mode does not support this either way: it currently accepts OAuth or no authentication only.
