@timergy/mcp

MCP server for Timergy - the scheduling poll app. Create polls, vote on time slots, and finalize meetings directly from AI agents like Claude, ChatGPT, and Gemini.

No authentication required. Works out of the box.

What is Timergy?

Timergy is a scheduling poll service (like Doodle or When2Meet). You create a poll with time slot options, share it with participants, everyone votes on their availability, and you pick the best time.

Quick Start

Claude Desktop / Claude Code

Add to your MCP config (~/.claude/claude_desktop_config.json or project .mcp.json):

{
  "mcpServers": {
    "timergy": {
      "command": "npx",
      "args": ["@timergy/mcp"]
    }
  }
}

Then just ask:

"Create a poll for dinner next Friday or Saturday evening"

Other MCP Clients

Any MCP-compatible client can use this server. Supports stdio (local) and Streamable HTTP (remote at https://api.timergy.com/mcp).

Tools

create_poll

Create a scheduling poll with time slot options.

Parameter	Type	Required	Description
title	string	yes	Poll title
options	array	yes	Time slots ({start, end} in ISO 8601 with timezone)
description	string	no	Poll description
deadline	string	no	Voting deadline (ISO 8601)
location	string	no	Event location
creatorName	string	no	Name shown as poll creator
autoFinalize	boolean	no	Auto-finalize when deadline passes (requires deadline)

Workflow

1. create_poll         ->  Get poll URL + passphrase
2. Share URL           ->  Send to participants
3. send_reminder       ->  Nudge non-voters (optional)
4. suggest_best_option ->  See ranked results with scores
5. finalize_poll       ->  Pick the best time, lock it in
   (or auto_finalize   ->  Let Timergy pick automatically)

The passphrase from step 1 is automatically remembered for steps 3-5 within the same session.
