Same issue here.
Same issue
Same issue for me too.
same again, status is always “not started"
this is with intellij ultimate and jetbrains ai ultimate
Same.
Can someone from Jetbrains help?
Same.
To add more context, I also analyzed the logs in “/home/user/.cache/JetBrains/PyCharm2025.1/log/mcp” to see what could be the cause. You get nothing nothing weird except an init timeout:
2025-06-27 08:55:45,057 CLIENT - Starting Slack MCP Server...
Connecting server to transport...
Slack MCP Server running on stdio
2025-06-27 08:55:40,921 INFO - Server started with init timeout 2000ms
2025-06-27 08:55:42,923 INFO - Server stopped
There should be a possibility to increase the timeout inside mcp.json. But it is not taken into acount by the configuration, so no way to add more parameters
Hello,
The issue looks similar to https://youtrack.jetbrains.com/issue/LLM-17481.
Please check if upgrading to the latest IDE and JetBrains AI Assistant plugin version can help.
The url in prior comment has an errand fullstop included in link. remove it to load.
fwiw: same issue.
I I invoke manually, from cli, I have a connected MCP waiting for whatever.
so IDE is just disconnecting.

I can confirm that updating ai assistant fixes the issue.
A separate issue here is that I had in fact gone and looked if there are any updates for plugin in the ide plugin setup/config.
I was shown no updates to the plugin, and that it was at latest up to date version. (no pending updates)
The issue being my IDE itself needed an update, to allow newer versions of ai assistant to be installed.
IMO, this is a bug, as i'd preferred to have seen an update pending, but get feedback/error that I need to update my IDE to get it. I could have saved me a day or so in time…
