MCP-Wait is a compact MCP server that pauses execution for a specified duration while providing progress updates. It’s useful for coordinating tasks in an MCP workflow where one step must wait for others to finish before continuing.

How to use

You can integrate MCP-Wait into your workflow as a stdio MCP server or test it locally via the CLI. It supports waiting for a defined number of seconds and reporting progress during the wait. The server can also run as an SSE-enabled HTTP endpoint for easy integration with other applications.

How to install

Prerequisites you need on your system before installing MCP-Wait:

Node.js and npm installed
Network access to install npm packages

Step 1: Install MCP-Wait via Smithery (recommended for Claude Desktop integration):

npx -y @smithery/cli install @automation-ai-labs/mcp-wait --client claude

Step 2: Manual installation (useful if you prefer local setup):

npm install

Additional setup and run instructions

To run and test MCP-Wait locally, you have several options depending on how you want to integrate it with your tooling.

# Start the server for CLI testing (uses the package’s dev script)
npm run dev

Inspect the server’s status and capabilities with the MCP Inspector web UI (CLI-based inspection command):

npm run inspect

Start the server with SSE support for integration with other applications (example shows setting transport type and port):

TRANSPORT_TYPE=sse PORT=8080 npm start

Wait Tool

The server provides a wait tool that pauses for a given number of seconds and reports progress along the way. You can configure the duration in seconds (0–30000).
