Hi @mhadjih2 , thanks for pointing this out - The lingering entry is likely not the MCP server block. The legacy uninstaller only removes enabledPlugins["memtrace-skills@memtrace"] and extraKnownMarketplaces.memtrace, but the your leftover "memtrace": { "repo": "syncable-dev/memtrace" } is a different marketplace shape, so it survives.

I'll have a look and will update it ASAP, thanks!

[mhadjih2]

Well, the MCP server block is also lingering I'm sorry to tell you. After a full removal, the MCP server complains it can't connect to memtrace also. I'll remove manually of course.

Hey @mhadjih2

Should be fixed and pushed on https://github.com/syncable-dev/memtrace-public/releases/tag/v0.3.25

Root cause: the uninstall path removed the skills/plugin in some cases, but did not reliably clean every Claude Code config shape. In affected installs, mcpServers.memtrace and/or the memtrace marketplace entry could remain in ~/.claude/settings.json, causing Claude to keep trying to start/connect to Memtrace after removal. The installer also used the GitHub shorthand marketplace source, which could hit SSH host-key failures on some machines.

What changed:

• Install now registers the public marketplace via HTTPS: https://github.com/syncable-dev/memtrace-public.git

• Uninstall now removes:

  • mcpServers.memtrace
  • enabledPlugins["memtrace-skills@memtrace"]
  • extraKnownMarketplaces.memtrace
  • legacy marketplace keys like syncable-dev-memtrace
  • marketplace cache dirs
  • installed plugin metadata
  • user-level Memtrace skills

• I Added regression coverage for the stale settings.json shape and verified cleanup against a temp Claude home.

For anyone already affected by the old release, update to the latest Memtrace and rerun memtrace uninstall. If the old binary is already gone, manually removing the lingering memtrace entries from ~/.claude/settings.json is still safe.

If it still fails, please let us know! thanks for reporting.

Closing this as fixed.
