[BUG] MCP drops chat context

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ x ] Other: Claude Teams (Desktop App)
• Claude CLI version: <!-- output of claude --version -->
• Operating System: macOS 15.5
• Terminal: <!-- e.g. iTerm2, Terminal App -->

Bug Description

We just started a Claude Team account. I have started 2 chats within a shared Project, which call some MCPs and execute some automated processes I've set up. After completing that process, the context from the chat completely disappears. This doesn't happen in my personal account - I'm not referring to my personal account tied to my team account, but the account I pay for separately under my personal email account. Under my personal account I am on a Max plan. We are testing the Team plan for collaboration so we are only at the basic level and I don't know if that has anything to do with it. Note that there are only 2 chats in my Teams account so nothing should be bogging down the memory.

Steps to Reproduce

1. Go to "Process Documentation" project folder
2. Start chat and paste documentation and prompt
3. Claude evokes MCPs and executes process successfully, writes it's thinking and tasks completed in the chat window, then after this it completely wipes out all of the context in the window that involved the MCPs. I ask it what happened doesn't know what I'm talking about - gaslighting.

Expected Behavior

Nothing should be disappearing from the chat.

Actual Behavior

All of the output that shows the MCPs evoked, thinking, and summary of what was done disappears.

Additional Context

I asked Claude to check the error logs and this is it's recommendation.

Content Disappearance - Likely Causes:

Session State Management Issues: The repeated timeout errors in the toast system suggest broader inter-process communication problems within Claude Desktop that could affect how conversation state is maintained.
Application Crashes/Restarts: The logs show frequent app restarts, which could lead to unsaved conversation state being lost if there were issues with the persistence layer.
Data Synchronization Problems: Issues with how Claude Desktop syncs conversation data locally or with Anthropic's servers.

The Real Issue:
The conversation content likely disappeared due to:

Internal application state management failures
Problems with local data persistence in Claude Desktop
Communication failures between Claude Desktop components affecting data saving
