That first URL is a Connect Link URL, which is used to connect an account to an app. I think you’re referring to the legacy MCP server URLs, which did not have auth on them. And that product is for end users directly, not for developers who want to integrate Pipedream MCP for their customers.
I am using a custom made mcp client where I can paste that url with the token and app Slug. I want to add another app but now I cannot find that same MCP server url format
mcp.pipedream.com is for direct consumers / Pipedream users. If you are building an app for your customers to use, you should consult the above docs I linked to. That’ll let you as the developer authenticate to Pipedream’s API and make tool calls on behalf of your users.
