Cal.com MCP Actor

319 tools for AI scheduling agents. PPE-enabled Apify Actor that wraps the cal-com-pp-mcp binary as a standby MCP server.

What It Does

Wraps Cal.com's Printing Press CLI (cal-com-pp-mcp) as an Apify standby MCP actor. AI agents can call 319 tools for booking management, event types, scheduling, analytics, teams, organizations, webhooks, and workflows.

MCP Client → Apify Standby → cal-com-pp-mcp → Cal.com API

Why Use It

• Offline agenda store: Sync bookings to local SQLite, query without API calls
• Full Cal.com coverage: 319 tools across bookings, events, schedules, analytics, teams, orgs
• PPE billing: Pay-per-event pricing via Apify ($0.03–$0.09 per tool)
• AI agent ready: MCP protocol compatible with Claude, GPT-4, and other LLM agents
• Humanized output: --json --compact --no-input --yes flags for agent Pipelines

FAQ

Q: How many tools are exposed? A: 319 — covering booking management, event types, scheduling, analytics, teams, organizations, webhooks, and workflows.

Q: Does it replace the Cal.com API key? A: No — you configure your own Cal.com credentials with the actor; it handles standby MCP serving so agents only pay when tools are used.
