Claude-to-Google-Calendar MCP Integration Module

Facilitate interactions with your Google Calendar environment directly through the Claude Desktop interface using the Model Context Protocol (MCP).

This integration is implemented as a Node.js/TypeScript-based MCP server, serving as a concrete example of MCP functionality while offering:

• Comprehensive manipulation of calendar entries via registered MCP Uniform Resource Identifiers (URIs).
• Dedicated functions for inserting and updating scheduled occurrences.
• Specialized methods for eliciting data-driven calendar appraisals.

Core Capabilities

Resource Abstraction

• Access chronological entries through distinct MCP URIs.
• Each managed item possesses attributes for subject, timing, detailed notes, and participant lists.
• Adherence to structured data formats with appropriate media type declarations.

Integrated Operations (Tools)

• schedule_new_occurrence: To schedule fresh calendar items.
• Accepts parameters such as the event's subject, its designated time slot, and supplementary metadata.
• Communicates directly with the underlying Google Calendar service APIs.
• retrieve_upcoming_events: To enumerate scheduled events in the near future.
• [Placeholder for additional implemented service operations]

Analytical Functions (Prompts)

• synthesize_time_analysis: To generate actionable intelligence regarding your commitments.
• Incorporates relevant upcoming entries as embedded data sources.
• Formats output specifically for sophisticated LLM interpretation.
• [Placeholder for additional analytical routines]

System Requirements

• Execution environment: Node.js (version 14 minimum)
• A provisioned Google Cloud Platform project with the Calendar API explicitly enabled.
• Valid OAuth 2.0 Client credentials established.

Local Development Setup

To establish the development environment using Devbox, follow the bootstrap instructions found at devbox.sh: bash curl -fsSL https://get.jetpack.io/devbox | bash

Initialize the Devbox configuration within the project directory: bash devbox init

Activate the isolated development shell: bash devbox shell

Install necessary JavaScript libraries: bash npm install

Compile the server codebase: bash npm run build

For continuous integration during development (watch mode): bash npm run watch

Integration with Claude Desktop

To enable this service with your Claude application, update the configuration file:

MacOS Location: ~/Library/Application Support/Claude/claude_desktop_config.json Windows Location: %APPDATA%/Claude/claude_desktop_config.json

Ensure the configuration block includes a reference to this server:

{ "mcpServers": { "Google Calendar Access": { "command": "/path/to/Google Calendar/build/index.js" } } }

Initial Authorization Procedure

1. Configure Cloud Credentials:
2. Navigate to the Google Cloud Console.
3. Select or establish a new project.
4. Verify that the Google Calendar API is toggled 'On'.
5. Generate OAuth 2.0 credentials (select 'Desktop application' type).

6. Save the resulting client secret file, renaming it precisely to .client_secret.json, and position it in the project's root directory.

7. First-Run Authentication Sequence:

8. Upon the server's initial execution, an authorization URL will be displayed.
9. Access this URL in any web browser.
10. Grant the permissions requested by the application.
11. Retrieve the resulting authorization code provided.
12. Input this code back into the command-line interface prompt when requested.

Troubleshooting Communication

As MCP servers communicate via standard input/output streams, conventional debugging can be complex. We strongly suggest utilizing the official MCP Inspector, accessible through a dedicated package script:

bash npm run inspector

The Inspector will provide a local address where you can open a browser interface for detailed diagnostic inspection.
