NullPointer at start after addition of some MCP-Server

[org-tekeli-borisp]

JavaClaw was running against a local Ollama instance.
The following MCP servers were added by the agent itself:
✅ brave-search
✅ weather
✅ filesystem
Now, if you restart JavaClaw, it crashes with a NullPointerException.

[borisp@javaclaw JavaClaw]$ ./gradlew :app:bootRun

Can you explain how you added the stdio MCP server? From the stacktrace, it appears a parameter is missing.

[org-tekeli-borisp]

Right after the initial setup, I asked the agent for the weather forecast. It replied that it couldn't do it at the moment because it was missing the necessary skills or tools. However, it offered to create the needed skills or add MCP servers. I agreed.
It then added the brave-search, weather, and filesystem MCP servers and asked if I would also like to add Google Drive, GitHub, PostgreSQL, or Git MCP servers. I asked for Git.
It seems something went wrong, and it proposed a restart, which I did.

Which model in Ollama?

[org-tekeli-borisp]

Qwen3.5-27B

[rdehuyss]

Ok, thanks.

Last question: in your application. private.yaml, some MCP servers were added, could you share this?

Thx!

Seems like serversConfiguration member in stdioPropetries is null. It's probably not the reason but the args's and env's in the connections objects.

[org-tekeli-borisp]

It's args
