Requesting redirect URI allowlist for MCP DCR

Title: How to get our redirect URI allowlisted for MCP DCR?

Body:

Hi team,

We're integrating Intercom's MCP server into our platform, which lets customers connect their own Intercom accounts to AI agents they build with us. When attempting Dynamic Client Registration, we get:

POST https://mcp.intercom.com/register
{
"error": "invalid_redirect_uri",
"error_description": "Redirect URI https://app.integry.io/auth/redirect/ is not in the allowlist, reach out to Intercom Customer Support if you believe we should support it"
}

A few questions:

  1. What's the process to request a production redirect URI be added to the allowlist? Is this handled through Customer Support, developer hub, or a partner channel?
  2. Are there review criteria or a security questionnaire we should prepare for?
  3. Can we allowlist a staging URI alongside production in the same request?
  4. As an alternative — does the MCP server accept access tokens issued by a standard Intercom OAuth app (via app.intercom.com/oauth) as bearer tokens? If so, that path would work for our use case without needing DCR. However, we prefer dynamic registration. So, interested in know all the steps involved there.
