Usage

You can run the MCP server using Docker with directory mounting to /projects:

{
  "mcpServers": {
    "npm-sentinel-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-w", "/projects",
        "--mount", "type=bind,src=${PWD},dst=/projects",
        "nekzus/npm-sentinel-mcp",
        "node",
        "dist/index.js"
      ]
    }
  }
}

For multiple directories:

{
  "mcpServers": {
    "npm-sentinel-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-w", "/projects",
        "--mount", "type=bind,src=/path/to/workspace,dst=/projects/workspace",
        "--mount", "type=bind,src=/path/to/other/dir,dst=/projects/other/dir,ro",
        "nekzus/npm-sentinel-mcp",
        "node",
        "dist/index.js"
      ]
    }
  }
}

Note: All mounted directories must be under /projects for proper access.
