⏰ TimeZest MCP Server

Bring your TimeZest scheduling data directly into Claude through the Model Context Protocol (MCP). Perform real-time appointment lookups, engineer briefings, and ticket-linked schedule management — all with natural language.

Registry ID: io.github.sagarkalra-tech/timezest-mcp

🌟 Why TimeZest MCP?

If you manage a team that uses TimeZest with ConnectWise, you know the pain: toggling between tabs, manually checking who's booked, chasing unbooked scheduling requests, and cross-referencing ticket numbers.

This MCP server turns Claude into a scheduling assistant that can:

🗓️ Give you a morning briefing of today's confirmed appointments grouped by engineer
🔍 Find appointments by ticket number — just say "find appointments for ticket #964400"
⏳ Surface aging unbooked requests that need follow-up
📊 Generate aggregate scheduling stats across your team
🕐 Handle timezone-accurate reporting across global MSP teams

🚀 Get Started in 30 Seconds

Prerequisites

Node.js 20+ — Download here
TimeZest API Key — Found in TimeZest → Settings → API

Option 1: Claude Desktop (Recommended)

Add this to your Claude Desktop configuration file:

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

config.json

{
  "mcpServers": {
    "timezest": {
      "command": "npx",
      "args": ["-y", "timezest-mcp@latest"],
      "env": {
        "TIMEZEST_API_KEY": "your-timezest-api-key-here"
      }
    }
  }
}

Restart Claude Desktop. You're done.

Option 2: Claude Code CLI

Terminal

claude mcp add-json timezest-mcp '{
  "command": "npx",
  "args": ["-y", "timezest-mcp@latest"],
  "env": {
    "TIMEZEST_API_KEY": "your-timezest-api-key-here"
  }
}'

Option 3: VS Code (Copilot)

Add to your .vscode/settings.json or User Settings:

config.json

{
  "mcp": {
    "servers": {
      "timezest": {
        "command": "npx",
        "args": ["-y", "timezest-mcp@latest"],
        "env": {
          "TIMEZEST_API_KEY": "your-timezest-api-key-here"

Tool	Description	Key Parameters
`get_todays_appointments`	Morning briefing — today's confirmed appointments grouped by engineer, plus pending unbooked requests	`timezone`
`list_appointments`	Flexible query across any date range with optional filters	`start_date`, `end_date`, `engineer_name`, `status`
`get_engineer_schedule`	All upcoming appointments for a specific engineer, sorted by time	`engineer_name`, `days_ahead`, `include_pending`
`list_pending_requests`	Unbooked invitations (sent/new) with age tracking in hours/days	`days_back`, `engineer_name`, `older_than_hours`
`find_appointment_by_ticket`	Find appointments linked to a ConnectWise ticket number	`ticket_number` (e.g., `964400` or `#964400`)
`get_appointment_types`	List all appointment type definitions configured in TimeZest	—
`get_appointment_stats`	Aggregate summary: counts by status, by engineer, today's load, oldest pending	`days_back`, `days_forward`
`list_cancelled_appointments`	Cancelled requests with scheduling URLs for rebooking	`days_back`, `engineer_name`

💬 Example Prompts

Once connected, just talk to Claude naturally:

Code

"Who are my top engineers today and what are they booked for?"

"Find any TimeZest requests for ticket #964400."

"Give me a morning briefing of today's confirmed vs. unbooked requests."

"Show me all pending scheduling requests older than 48 hours."

"What's the scheduling volume breakdown for the last two weeks?"

"Pull up Sarah's schedule for the next 5 days."

"List all cancelled appointments from last week — any we should rebook?"

⚙️ Configuration

Environment Variable	Required	Default	Purpose
`TIMEZEST_API_KEY`	Yes	—	Your TimeZest Bearer token (Settings → API)
`TIMEZEST_DEFAULT_TZ`	No	`America/Chicago`	Default IANA timezone for localized display strings
`TIMEZEST_WINDOW_DAYS_BACK`	No	`14`	How many days back to fetch scheduling requests
`TIMEZEST_WINDOW_DAYS_FORWARD`	No	`30`	How many days forward to fetch scheduling requests

Key Design Decisions

Read-Only: Intentionally kept read-only — no mutations to your scheduling data
Resilient Client: Exponential backoff with automatic Retry-After header support for 429/5xx errors
Deep Pagination: Recursively crawls all pages (50-item chunks) to build complete datasets
Timezone Precision: Converts Unix timestamps to strict ISO with localized display strings using IANA timezone identifiers
Engineer Resolution: Uses a "highest-confidence" search — checks scheduled_agents first, then falls back to resources
Warm Cache: Appointment types are cached after first fetch to reduce API overhead

🧪 Testing

The server ships with a comprehensive Vitest test suite — 22 tests across 3 files:

Test File	Tests	Coverage
`transform.test.ts`	8	Engineer resolution, ticket extraction, timezone conversion, graceful handling of missing fields
`filter.test.ts`	6	Case-insensitive partial matching, team name matching, date-range filtering
`client.test.ts`	8	Appointment type caching, pagination, retry on 429/5xx, no-retry on 4xx

All tests use mocked API responses — no live API calls, no secrets needed.
