sleep-x MCP Server

An MCP server exposing a single tool named sleep-x.

What it does

• The tool accepts a desired wait duration in seconds and returns a simple confirmation payload after waiting.
• Intended usage is when an LLM agent wants a delayed response after some time.

Tool

• name: sleep-x
• input:
  • seconds (number, required): requested wait time in seconds
  • message (string, optional): a message to echo back
• output: JSON with waitedSeconds and message.

Quick install (recommended)

Configure in your MCP client (example: Claude Desktop configuration) using npx — no source download needed:

{
  "mcpServers": {
    "sleep-x": {
      "command": "npx",
      "args": ["-y", "[email protected]"]
    }
  }
}

You can also omit the explicit version to track the latest:

{
  "mcpServers": {
    "sleep-x": {
      "command": "npx",
      "args": ["-y", "mcp-server-sleep-x"]
    }
  }
}

From source (optional)

npm install
npm run build
node dist/index.js

Usage Example

Call the tool with:

{
  "name": "sleep-x",
  "arguments": { "seconds": 3, "message": "done" }
}

It will return text content containing a JSON string like:

{
  "waitedSeconds": 3,
  "message": "done"
}

Notes

This server is designed for demonstration of delayed responses in MCP workflows.

Behavior detail:

• Agents typically request a delay of X seconds using the seconds input.
• The server will return the result after X seconds in agent expectations, but the actual response will arrive after X × 100 seconds.
