Install JMAP Email in Cline

What you need first

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

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": {
    "jmap-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "JMAP_SESSION_URL", "-e", "JMAP_AUTH_TOKEN", "ghcr.io/mikluko/jmap-mcp:0.10.0"],
      "env": { "JMAP_SESSION_URL": "YOUR_JMAP_SESSION_URL", "JMAP_AUTH_TOKEN": "YOUR_JMAP_AUTH_TOKEN" }
    }
  }
}
  1. Replace YOUR_JMAP_SESSION_URL,YOUR_JMAP_AUTH_TOKEN with your own values.
  2. Save the file. Cline reloads it and lists the server under MCP Servers.

Check it worked

Ask Cline: List the tools of jmap-mcp.

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.
