mcp-wait

A minimal MCP server that lets AI agents pause for a specified duration before resuming their workflow. Useful for polling patterns: check a condition, wait, retry.

Use cases

• Wait for a PR to be approved before merging

• Wait for a Slack response before continuing a conversation

• Wait for a file to be created by an external process

• Any retry/polling loop where the agent needs to back off

Tool: wait

Returns a confirmation message once the delay has elapsed.

Quick start with npx

No installation needed — just add to your MCP configuration:

{
  "mcpServers": {
    "mcp-wait": {
      "command": "npx",
      "args": ["-y", "@lzientek/mcp-wait"]
    }
  }
}

Install globally

npm install -g @lzientek/mcp-wait

Then use in your MCP config:

{
  "mcpServers": {
    "mcp-wait": {
      "command": "mcp-wait"
    }
  }
}

Example agent flow

1. Check PR status → not approved
2. Call wait(seconds: 180, reason: "waiting for PR approval")
3. (3 minutes pass)
4. Check PR status again → approved ✓
5. Proceed with merge
