What is MCP and do I need to understand it?

MCP (Model Context Protocol) is an open standard that lets AI agents connect to external tools. Think of it as a universal adapter. You don’t need to understand it — just connect Callsy to your AI tool and it works.

Does Callsy work with OpenClaw?

Absolutely. Callsy’s MCP server integrates directly with OpenClaw agents. Add it as a skill and your autonomous agent can create voice personas, initiate calls, and check outcomes — all within the agent loop.

Do I need to be technical to use this?

Not at all. If you can type a sentence, you can use Callsy. Describe your call in plain English.

What does the AI voice sound like?

Natural and conversational — not robotic. You choose from multiple voice profiles and customize tone, pace, and personality to match your brand.

Can the AI handle objections?

Yes. You define the playbook — common objections, discount authority, escalation triggers. The agent follows your rules and can warm-transfer to a human at any point.

Is there a free trial?

Yes — the free tier includes 10 calls with no credit card. All paid plans also come with a 7-day money-back guarantee.
