Can AI Agent Studio connect to external/custom MCP servers as a client?

Hi everyone,

I'm currently exploring MCP integration with AA AI Agent Studio at ai.automationanywhere.com.

I understand that AA exposes its automations as an MCP server, which allows external MCP clients like Microsoft Copilot Studio or Claude to call AA automations. This works great.

However, I'm trying to do the opposite direction, I want AA's AI Agent Studio to act as an MCP client and connect to our own custom MCP server.

I see the "MCP Servers" section in the Advanced Configuration with "Add Server" and pre-configured options like Sentry, but when I add a custom HTTP server with custom headers for Bearer token auth, the connection fails with 401, even though the same endpoint and credentials work fine from other MCP clients (Claude Code, curl, etc.).

My questions:

1. Does AI Agent Studio currently support connecting to arbitrary external MCP servers as a client (not just pre-listed ones like Sentry)?
2. Are custom headers (specifically Authorization: Bearer <token>) actually sent during the MCP HTTP transport handshake?
3. If this is not currently supported, is outbound MCP client capability (consuming external MCP servers) on the product roadmap?
4. Is there a recommended workaround in the meantime, for example, using API Tasks within automations to call an external MCP endpoint directly?

Any guidance from the AA team or community members who have tried this would be greatly appreciated.

Thanks!
