Worker connection fails on every plugin update

[somethingforheheda]

Description

I'm experiencing two recurring errors with the claude-mem plugin:

1. MCP server fails on every plugin update - Race condition with dependency installation
2. Summary hook fails on every response - Database error after each assistant response

Both errors significantly disrupt the user experience.

Issue 1: MCP Server Fails on Plugin Update

Steps to Reproduce

1. Have claude-mem plugin installed
2. Plugin receives an update
3. Start a new Claude Code session
4. Check /plugin - MCP server shows "failed" status

Error Log

⚠️ Claude-Mem: First-Time Setup

Dependencies are installing in the background. This only happens once.

Error: Worker service connection failed.

To restart the worker:

1. Exit Claude Code completely
2. Open Terminal
3. Navigate to: ~/.claude/plugins/marketplaces/thedotmack
4. Run: npm run worker:restart
5. Restart Claude Code

Node.js v20.19.5

Impact

• MCP server (claude-mem-search) remains in "failed" state
• Memory search functionality unavailable for the entire session
• Requires restart to recover
• Happens on every plugin update

Issue 2: Summary Hook Fails on Every Response

Steps to Reproduce

1. Start a Claude Code session
2. Ask any question and receive a response
3. Error appears after every assistant response

Error Log

Stop says: Plugin hook error: [2025-12-15 03:17:17.653] [ERROR] [HOOK ] ✗ Failed to generate summary {status=500}
{"error":"undefined is not an object (evaluating 'o.lastInsertRowid')"}

(file:///Users//.claude/plugins/cache/thedotmack/claude-mem/7.0.11/scripts/summary-hook.js:20:1388)

Node.js v20.19.5

Impact

• Error message appears after every response
• Very disruptive to the reading experience
• Appears to be a database-related error (lastInsertRowid suggests SQLite issue)

---

Environment

• Plugin version: 7.2.1 (also saw 7.0.11 in error logs)
• Node.js: v20.19.5
• Bun: v1.0.18
• Platform: macOS

[github-actions]

The GitHub issue highlights a race condition in the claude-mem plugin during updates, where the worker connection fails on startup because the script attempts to connect to the worker before dependency installation is complete. While the worker starts successfully after a few seconds and passes the health check, the issue leaves the MCP server in a "failed" state, requiring manual intervention to restart. The problem occurs with every plugin update. The reported behavior suggests that the plugin should either wait until dependency installation finishes before initiating the worker connection or implement a retry mechanism to handle the initial failure gracefully. Relevant environment details include plugin version 7.2.1, Node.js v20.19.5, Bun v1.0.18, and macOS as the platform.

@somethingforheheda This is an issue with their caching, you just have to restart claude code. To restart and not lose your place, start it up with claude --continue

[thedotmack]

I'm going to investigate a bit further

@somethingforheheda So I did some poking around, wanted to do testing, but am on Opus so it doesn't listen to my prompts... it pushed a "fix" for this, please let me know if it helped.

And unfortunately otherwise the way to do this is to restart claude code cause it doesn't re-register the hooks like it used to now that they are caching the plugins in a different structure.

I still have the same problem when I download this version
