Install Project Brain in Cline

What you need first

• Cline, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_PROJECT_BRAIN_REPO_LIST,YOUR_PROJECT_BRAIN_STATE_DIR.

Steps

1. In Cline, open the MCP Servers icon, then the Configure tab, and choose Configure MCP Servers. It opens cline_mcp_settings.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "project-brain": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "PROJECT_BRAIN_REPO_LIST", "-e", "PROJECT_BRAIN_STATE_DIR", "ghcr.io/gentleelephant/project-brain:v2.0.3"],
      "env": { "PROJECT_BRAIN_REPO_LIST": "YOUR_PROJECT_BRAIN_REPO_LIST", "PROJECT_BRAIN_STATE_DIR": "YOUR_PROJECT_BRAIN_STATE_DIR" }
    }
  }
}

3. Replace YOUR_PROJECT_BRAIN_REPO_LIST,YOUR_PROJECT_BRAIN_STATE_DIR with your own values.
4. Save the file. Cline reloads it and lists the server under MCP Servers.

Check it worked

Ask Cline: List the tools of project-brain.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart Cline.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
