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.

Hi ​@User2185 , Seán here from the Fin technical support team 👋

 

As Yaroslav explained in the conversation we need to request the registration to the allow list internally which has been resolved for you! For those looking to do the same please reach out to Intercom support directly through the workspace and to help speed things up, it’s useful to include the information needed for the request:

  • your product or tool name
  • the exact redirect URI(s) you want reviewed
  • whether each URI is production or staging
  • the MCP endpoint you’re targeting
  • a short summary of your use case and distribution model

Any issues just let us know we’re here to help!
