How to Connect Slotwise as an MCP Server for Claude, Cursor, and ChatGPT

The Shift from Manual Links to Autonomous AI Scheduling

In 2026, calendar coordination is evolving beyond human-clicked links. Software engineers, executives, and agency founders increasingly delegate their workflow to AI agents running in Claude Desktop, Cursor IDE, and ChatGPT.

However, legacy scheduling tools like Calendly and Acuity force users into proprietary web forms designed strictly for human eyeballs, failing when autonomous agents attempt to query availability programmatically.

Slotwise is engineered with native support for the Model Context Protocol (MCP), the open standard pioneered by Anthropic that connects AI models to external tools and data sources.

What Can Your AI Agent Do with Slotwise MCP?

With Slotwise MCP configured, your personal AI assistant can:

1. Query Real-Time Availability: "Claude, am I free for a 45-minute sync with Acme Corp this Thursday afternoon?"
2. Discover Mutual Slots: Cross-reference your host working hours and busy calendar blocks in milliseconds.
3. Generate Confirmed Bookings: "Create a 30-min kickoff meeting with [email protected] and generate a Google Meet link."
4. Zero Human Back-and-Forth: The agent performs the booking, writes the calendar event, and dispatches confirmation emails automatically.

Step-by-Step: Adding Slotwise to Claude Desktop

Connecting Slotwise to Claude Desktop takes under two minutes.

Step 1: Obtain Your Slotwise API Key or Access Token

Navigate to Slotwise Dashboard > Settings > Developer Platform and generate an API access token.

Step 2: Open Claude Desktop Configuration

Open your Claude Desktop config file:

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

Step 3: Add Slotwise MCP Server Definition

Add the Slotwise server to your mcpServers block:

{
  "mcpServers": {
    "slotwise": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-fetch",
        "https://slotwise.nxtgenstack.in/mcp"
      ],
      "env": {
        "SLOTWISE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Restart Claude Desktop. You will now see the Slotwise hammer icon representing active calendar tools!

Direct ChatGPT & Cursor Integration

Slotwise also exposes an OpenAPI 3.1 specification at:

https://slotwise.nxtgenstack.in/.well-known/ai-plugin.json
https://slotwise.nxtgenstack.in/api/v1/openapi.yaml

You can import this manifest directly into ChatGPT Custom GPT Actions or Cursor Custom Agent Rules to grant full scheduling autonomy to your development environment.

Zero Telemetry & Enterprise Privacy

When interacting through MCP, privacy is strictly preserved:

• No Third-Party Analytics: Zero ad beacons or tracking scripts are loaded during API interactions.
• Granular Permissions: Token scopes restrict agents to specific event types or calendar windows.
• Audit Logs: Every booking action initiated by an AI agent is timestamped and logged in your Slotwise dashboard.
