Hey i’m having issues using pipedream mcp with cursor.
• i setted up some mcps from here
• copied the code to cursor mcp.json

{
  "mcpServers": {
    "Google Play": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/google_play"
    },
    "Slack": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/slack"
    },
    "Notion": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/notion"
    },
      "Google Drive": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/google_drive"
    },
    "Google Sheets": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/google_sheets"
    },
    "Google Forms": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/google_forms"
    },
    "Discord Bot": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/discord_bot"
    },
    "Google Analytics": {
      "url": "https://mcp.pipedream.net/[YOUR-UNIQUE-ID]/google_analytics"
    },
    "Browser Tools": {
      "command": "npx @agentdeskai/browser-tools-mcp@latest"
    }    
  }
}

when i want to use it in chat i get this:
"I notice we're having issues with the authentication. Let's try once more with this updated URL:
https://pipedream.com/_static/connect.html?token=ctok_[ANOTHER-UNIQUE-ID]&connectLink=true&app=google_play_
Please complete the authentication process. Once done, let me know and I'll make another attempt to search for "ring" discussions in your Slack."

this link brings me to a 404 page. probably claude is halucinating and creating random links.
What’s wrong? Sth with OAuth?

looks like you have already connected your accounts with those apps, can you try prompting differently and see if claude figures out that it doesn’t need to do that?

thanks. still not successful. any idea what else i could do?

hmm have you tried using your slack auth in pipedream workflows?

5

is it a corp account?

6

Could be that corp account blocks this api requests

7

have connected it but not used so far

Ugh that’s an annoying issue that we only see in Cursor for some reason. For some reason it removes an underscore before static in that url, so it should look like this:

https://pipedream.com/_static…

We have a fix on the backlog, you can also connect your accounts in the UI at mcp.pipedream.com to sidestep the issue

i did initially but cursor had issues as if i didn’t

11

Interesting, was it just not finding the connected account?

12

I was able to access a slack msg but the connection seems to drop frequently in cursor mcp settings and chat. To most of other services i tested like analytics and google play it couldn’t establish a connection even after fixing the link and repeating oauth.

13

Interesting, we had seen that previously, but we’ve shipped some improvements to the SSE handling and timeout behavior, and in theory Cursor should be able to gracefully reconnect, since there’s no actual state to maintain.

14

Have you seen similar issues w/ any other MCP servers?

15

okay slack works nicely wow. but google play and analytics has issues and results in 404

Can you show me exactly what you’re seeing / trying to do? There are some known configuration issues with some tools that we’re working on addressing, but I’d like to confirm if there’s some other issue that you’re running in to.
