Sleep MCP Server

smithery badge

This MCP server attempts to pause execution for a specified duration to control the flow of your agents. Enhance your automation by introducing timed delays, ensuring tasks are executed in the desired sequence. Ideal for managing workflows that require waiting periods between actions.

Sleep MCP Server

Tools

  1. sleep
    • Pause execution for a specified duration to control the flow of your agents.
    • Inputs:
      • seconds (number, max timeout config value): Seconds it will take me to tell you to continue
    • Returns: You will receive the sentence after {seconds} "You can continue to do your task after you've been waiting {seconds} seconds". If you enter a waiting time greater than the maximum time the result will be "My configuration does not allow me to make you wait more than {ctx.sleep.config.timeout} seconds"

Usage with Claude Desktop

To use this with Claude Desktop, add the following to your claude_desktop_config.json:

Docker

{
  "mcpServers": {
    "mcp-sleep": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "MCP_SLEEP_TIMEOUT",
        "mcp/sleep"
      ],
      "env": {
        "MCP_SLEEP_TIMEOUT": "<MCP_SLEEP_TIMEOUT>"
      }
    }
  }
}

Development

Config

If you are working locally add two environment variables to a .env file in the root of the repository:

MCP_SLEEP_TIMEOUT=

For local development, update your Claude Desktop configuration:

{
  "mcpServers": {
      "mcp-sleep_local": {
          "command": "uv",
          "args": [
              "run",
              "--directory",
              "/path/to/your/mcp-sleep",
              "run",
              "mcp-sleep"
          ]
      }
  }
}
Published Servers Configuration 
"mcpServers": {
  "mcp-sleep": {
    "command": "uvx",
    "args": [
      "mcp-sleep"
    ]
  }
}

Building and Publishing

To prepare the package for distribution:

  1. Sync dependencies and update lockfile:
uv sync
  1. Build package distributions:
uv build

This will create source and wheel distributions in the dist/ directory.

  1. Publish to PyPI:
uv publish

Note: You'll need to set PyPI credentials via environment variables or command flags:

  • Token: --token or UV_PUBLISH_TOKEN
  • Or username/password: --username/UV_PUBLISH_USERNAME and --password/UV_PUBLISH_PASSWORD

Docker build:

docker build -t mcp/sleep -f Dockerfile .

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging experience, we strongly recommend using the MCP Inspector.

You can launch the MCP Inspector via npm with this command:

npx @modelcontextprotocol/inspector uv --directory /path/to/your/mcp-sleep run mcp-sleep

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
