Uninstalling the Old Local Armbrain (Coppermind)

If you were set up with the original Python-based local server (pip install coppermind-cmo or uvx coppermind-cmo, formerly called Coppermind), that local server conflicts with the new remote gateway at api.coppermind.app. Follow these steps to remove the old installation and switch to the remote version.

Step 1: Remove from Claude Desktop

1. Open Claude Desktop.
2. Go to Settings (gear icon) > Connectors (or MCP Servers).
3. Find the Armbrain (or Coppermind) entry. Click the three-dot menu and select Remove or Delete.
4. Also check the config file for leftover entries:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

1. Open the file in a text editor. If you see a "coppermind-cmo" key inside "mcpServers", delete that entire block. Save the file.
2. Quit and reopen Claude Desktop.

Step 2: Remove from Claude Code

1. List your configured MCP servers:

```

claude mcp list

```

1. If coppermind-cmo appears, remove it:

```

claude mcp remove coppermind-cmo

```

1. Verify it is gone by checking ~/.claude/settings.json for any remaining coppermind-cmo references. Remove them if found.

Step 3: Uninstall the Python Package

Run whichever command matches how you originally installed it:

pip uninstall coppermind-cmo

or

pipx uninstall coppermind-cmo

If neither command recognizes the package, it may already be removed.

Optionally, clean up any leftover config directory:

rm -rf ~/.config/coppermind-cmo/

Step 4: Verify Clean State

1. Restart Claude Desktop and/or start a new Claude Code session.
2. Confirm the old local server no longer appears in your connectors or MCP server list.
3. Only the new remote gateway (api.coppermind.app) should be present.

If you do not yet have the new remote gateway configured, see the Installation and Setup guide.
