Introduction

OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Google Calendar with authentication management handled for you. You can execute actions on Google Calendar via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?

Apart from a managed and hosted MCP server, you will get:

Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
Handling Large tool responses out of LLM context to minimize context rot.
Dynamic just-in-time access to 20,000 tools across 1500+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

How to install Google Calendar with OpenClaw

Using Composio API Key and Setup Prompt

Go to dashboard.composio.dev
Copy the setup prompt

Copy the setup prompt from the OpenClaw dashboard

Run it in your OpenClaw chat interface.
Authenticate Google Calendar from the dashboard
Go back to your OpenClaw interface and start asking questions.

Using OpenClaw/Composio Plugin

1. Install OpenClaw Composio plugin

bash

openclaw plugins install @composio/openclaw-plugin

2. Copy the API Key from dashboard.composio.dev

3. Setup OpenClaw Config

bash

openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"

4. Restart OpenClaw

bash

openclaw gateway restart

5. Go to your chat interface and start asking questions.

6. When prompted, authenticate the app and you're all set.

How It Works

The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.

If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

Configuration

bash

{
  "plugins": {
    "entries": {
      "composio": {
        "enabled": true,
        "config": {
          "consumerKey": "ck_your_key_here"
        }
      }
    }
  }
}

Option	Description	Default
`enabled`	Enable or disable the plugin	`true`
`consumerKey`	Your Composio consumer key (`ck_...`)	—
`mcpUrl`	MCP server URL (advanced)	`https://connect.composio.dev/mcp`

What is the Google Calendar MCP server, and what's possible with it?

The Google Calendar MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Calendar account. It provides structured and secure access to your calendars, events, availability, and sharing settings, so your agent can schedule meetings, find events, check availability, update plans, and manage calendars on your behalf.

Event scheduling and updates: Have your agent create events with set times or durations, change event details, and delete canceled plans.
Event search and review: Instruct your agent to find events by keywords or time range, retrieve event details, and review instances of recurring events.
Availability checks: Let the agent check busy periods across one or more calendars before arranging a meeting.
Calendar organization: Direct your agent to create, rename, update, delete, add, or remove calendars from your calendar list.
Calendar access management: Have your agent create, review, or remove calendar access rules to control sharing.

Conclusion

You've successfully integrated Google Calendar with OpenClaw using Composio plugin. Now interact with Google Calendar directly from your terminal, Web UI, or any messenger app using natural language commands.

Key benefits of this setup:

Seamless integration across TUI, Web UIs, and Messenger apps like Telegram, WhatsApp, Slack, etc.
Natural language commands for Google Calendar operations
Managed authentication through Composio
Access to 20,000+ tools across 1500+ apps for cross-app workflows

FAQ

Frequently asked questions

With a standalone Google Calendar MCP server, the agents and LLMs can only access a fixed set of Google Calendar tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Google Calendar and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Google Calendar tools.

Yes, absolutely. You can configure which Google Calendar scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Google Calendar data and credentials are handled as safely as possible.
