Summary

This skill itself is an open-source prompt-style wrapper, but it depends on remote Rube MCP and a Google Calendar connection to discover and execute tools, so the overall posture is caution rather than high risk. No clear malicious red flags are visible in the material, but calendar operations and potentially user data are delegated to a third-party service chain.

CredentialsCaution

The material says 'no API keys needed,' but it still requires creating a googlecalendar connection via RUBE_MANAGE_CONNECTIONS and completing an auth-link flow, which implies Google account authorization tokens are involved. Credentials are not exposed as install-time parameters, but there is the normal risk of a third-party intermediary holding or using the authorized connection.

Network egressCaution

It explicitly requires adding the remote MCP endpoint https://rube.app/mcp and using composio/rube-related services to search tools, manage connections, and execute actions. This means task descriptions, session information, and calendar operation parameters will be sent to the declared third-party endpoint, but no additional unknown exfiltration target is shown.

Code executionLow risk

Per the stated checks, this is a prompt-only skill, and the material does not show local install scripts, shell execution, process spawning, or system command capability. Execution occurs in the remote toolchain rather than as local code on the user's machine.

Data accessCaution

The purpose is to automate Google Calendar operations, which typically requires reading or modifying calendar events, schedules, and related account data. The material does not indicate access to local files or broader system-level data, but the remote service can access user content related to calendar tasks.

Supply chainLow risk

The source is an open-source GitHub repository with strong community adoption (64.7k stars), which materially lowers supply-chain risk. What is provided appears to be a skill description within awesome-claude-skills rather than a separate closed-source binary; although the license and maintenance status are unclear and it depends on external Rube/Composio services, no obvious suspicious or injection-like content is visible.

Recommendations

Only connect a Google account if you trust the Rube/Composio service chain, and verify that OAuth scopes are limited to calendar needs.
Do not include unnecessary sensitive information in calendar requests; assume prompts and parameters are sent to the rube.app/Composio service path.
Prefer a segregated test account or restricted calendar first to validate the real action scope.
Regularly review and revoke unused Google authorizations, and monitor maintenance changes in the upstream repository and Rube MCP.

Google Calendar Automation via Rube MCP

Automate Google Calendar operations through Composio's Google Calendar toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/googlecalendar

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active Google Calendar connection via RUBE_MANAGE_CONNECTIONS with toolkit googlecalendar
Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
Call RUBE_MANAGE_CONNECTIONS with toolkit googlecalendar
If connection is not ACTIVE, follow the returned auth link to complete setup
Confirm connection status shows ACTIVE before running any workflows

Tool Discovery

Always discover available tools before executing workflows:

RUBE_SEARCH_TOOLS
queries: [{use_case: "Google Calendar operations", known_fields: ""}]
session: {generate_id: true}

This returns available tool slugs, input schemas, recommended execution plans, and known pitfalls.

Core Workflow Pattern

Step 1: Discover Available Tools

RUBE_SEARCH_TOOLS
queries: [{use_case: "your specific Google Calendar task"}]
session: {id: "existing_session_id"}

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS
toolkits: ["googlecalendar"]
session_id: "your_session_id"

Step 3: Execute Tools

RUBE_MULTI_EXECUTE_TOOL
tools: [{
  tool_slug: "TOOL_SLUG_FROM_SEARCH",
  arguments: {/* schema-compliant args from search results */}
}]
memory: {}
session_id: "your_session_id"

Known Pitfalls

Always search first: Tool schemas change. Never hardcode tool slugs or arguments without calling RUBE_SEARCH_TOOLS
Check connection: Verify RUBE_MANAGE_CONNECTIONS shows ACTIVE status before executing tools
Schema compliance: Use exact field names and types from the search results
Memory parameter: Always include memory in RUBE_MULTI_EXECUTE_TOOL calls, even if empty ({})
Session reuse: Reuse session IDs within a workflow. Generate new ones for new workflows
Pagination: Check responses for pagination tokens and continue fetching until complete

Quick Reference

Operation	Approach
Find tools	`RUBE_SEARCH_TOOLS` with Google Calendar-specific use case
Connect	`RUBE_MANAGE_CONNECTIONS` with toolkit `googlecalendar`
Execute	`RUBE_MULTI_EXECUTE_TOOL` with discovered tool slugs
Bulk ops	`RUBE_REMOTE_WORKBENCH` with `run_composio_tool()`
Full schema	`RUBE_GET_TOOL_SCHEMAS` for tools with `schemaRef`
