I'm trying to integrate Claude Code with my OutSystems ODC environment 

following the official OutSystems MCP GitHub repository guide, but I'm 

encountering a 404 error when Claude Code attempts to reach the /mcp endpoint.

STEPS I'VE COMPLETED:

1. Installed Claude Code and configured the plugin:

   - `claude plugin marketplace add OutSystems/outsystems-mcp`

   - `claude plugin install outsystems@outsystems`

   - `claude mcp add -s user --transport http --client-id service_studio 

     --callback-port 7890 outsystems https://<company>.outsystems.dev/mcp`

2. Verified my tenant hostname is correct (<company> .outsystems.dev) by 

   successfully accessing the authentication endpoints:

   - https://<company> .outsystems.dev/auth/realms/.../protocol/openid-connect/auth

   - https://<company> .outsystems.dev/authentication/login

3. Restarted Claude Code

THE PROBLEM:

When I try to use Claude Code with OutSystems, I get an HTTP 404 error 

when attempting to access https://<company> .outsystems.dev/mcp

The /mcp endpoint returns: "No webpage was found for the web address"

WHAT I'VE VERIFIED:

- The tenant address is correct and reachable

- Authentication endpoints are working

- The MCP plugin is installed in Claude Code

QUESTION:

Does the OutSystems MCP server need to be explicitly enabled or configured 

on the OutSystems tenant side? Or is there additional setup required in 

OutSystems admin panel?

ENVIRONMENT:

- Claude Code: 2.1.224

- OutSystems: ODC

- Tenant: <company> .outsystems.dev
