MCP is starting to throw the session error after a while

Workaround: MCP reconnection triggered from a client (Claude Code / Opencode) seems to fix the session issue

My setup:
OS: Arch
Ghidra: 11.4.2-1

[cyberkaida]

Please try the latest version. The MCP library is upgraded.

[wishiweresaitama]

Sorry, I forgot to mention that I am using the latest 7.1.1 version of the plugin. However, I'll give it a shot with the newest ghidra and let you know!

[wishiweresaitama]

Unfortunately the issue persists with Ghidra 12.0 and 12.0.2 as well
API Key Auth is disabled. I'll try to gather some information with enabled "debug" option and provide more info

Thank you for updating! 🙇‍♀️

After this happens please use the debug capture feature. You can also reconnect your MCP client and ask the agent to capture ReVa debug information. The tool is capture-reva-debug-info

Please review this capture before posting. It will contain some details about your project, the file you are working on, the log of your ReVa tool use. If this is sensitive you can DM me on Discord.
