My agent doesn’t use Welder
Your agent decides when to call Welder from its Server description, so say plainly what it does, for example: Posts videos, photos and carousels to my social accounts. To change it later, edit the connector under Custom connectors in Power Apps or Power Automate.
Welder is blocked in my organization
Copilot Studio reaches MCP servers through Power Platform connectors, so your organization’s data policy applies to Welder. Ask your admin to allow it.
Welder says posting more isn’t included
Your first 3 posts are free. After that, posting needs a plan: start your 3-day free trial in the Welder app at weldergtm.com, then ask again. Connecting accounts, uploading and checking a post work either way.
Prefer to use a key instead?Copilot Studio asks for the key when you create the connection. Create one under Advanced → Keys in the app; it is shown once.
In the wizard, choose API key, Type Header and enter Authorization as the header name. When you create the connection, enter the key like this:
