Cal Automation

Cal Automation via Composio MCP

Automate Cal operations through Composio's Cal toolkit via Composio MCP.

Toolkit docs: composio.dev/toolkits/cal

Prerequisites

• Composio MCP must be connected (COMPOSIO_SEARCH_TOOLS available)
• Active Cal connection via COMPOSIO_MANAGE_CONNECTIONS with toolkit cal
• Always call COMPOSIO_SEARCH_TOOLS first to get current tool schemas

Setup

Get Composio MCP: Add http://localhost:8787/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Composio MCP is available by confirming COMPOSIO_SEARCH_TOOLS responds
2. Call COMPOSIO_MANAGE_CONNECTIONS with toolkit cal
3. If connection is not ACTIVE, follow the returned auth link to complete setup
4. Confirm connection status shows ACTIVE before running any workflows

Tool Discovery

Always discover available tools before executing workflows:

COMPOSIO_SEARCH_TOOLS
queries: [{use_case: "Cal 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

COMPOSIO_SEARCH_TOOLS
queries: [{use_case: "your specific Cal task"}]
session: {id: "existing_session_id"}

Step 2: Check Connection

COMPOSIO_MANAGE_CONNECTIONS
toolkits: ["cal"]
session_id: "your_session_id"

Step 3: Execute Tools

COMPOSIO_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 COMPOSIO_SEARCH_TOOLS
• Check connection: Verify COMPOSIO_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 COMPOSIO_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
