Install Redmine in LM Studio

What you need first

• LM Studio, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_REDMINE_SERVER,YOUR_REDMINE_API_KEY.

Steps

1. In LM Studio, open the Program tab and choose Install › Edit mcp.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "redmine-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "REDMINE_SERVER", "-e", "REDMINE_API_KEY", "ghcr.io/aarondpn/redmine-mcp:2.14.1"],
      "env": { "REDMINE_SERVER": "YOUR_REDMINE_SERVER", "REDMINE_API_KEY": "YOUR_REDMINE_API_KEY" }
    }
  }
}

3. Replace YOUR_REDMINE_SERVER,YOUR_REDMINE_API_KEY with your own values.
4. Save the file and restart LM Studio.

Check it worked

Ask LM Studio: List the tools of redmine-mcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart LM Studio.

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.
