Your agent has 100+ skills. It browses the web. Writes code. Manages databases. But the moment a workflow needs a real phone call — a cart recovery, a lead follow-up, a booking confirmation — it goes silent.
No Twilio. No telephony. No code. Just describe the call and Callsy handles the rest.
Add Callsy's MCP server to Claude, OpenClaw, your automation tool, or your own codebase. Five-minute setup. Zero telephony needed.
Tell your agent who to call and why. Plain English. Or let a Shopify abandoned-cart event trigger it automatically.
Callsy's voice agent makes the call, follows your playbook, handles objections, and reports back with a full transcript.
Your AI detects an abandoned cart and calls the customer within minutes. It offers help, answers questions, and closes the sale — while your team sleeps.
Building with OpenClaw, Claude, or GPT? Callsy slots in as an MCP tool. Your agent can now make phone calls as part of any autonomous workflow.
Wire Callsy into client Shopify stores, CRMs, or custom pipelines in an afternoon. New revenue stream, zero infrastructure, incredible margins.
Three tools. That's all your agent needs to start making real phone calls.
Spin up a voice agent with custom personality, script, guardrails, and tone of voice.
Trigger a real phone call to any number using your configured voice agent.
Check call outcome, pull the transcript, and get next-step recommendations.
Lock in founder rates before we raise prices. One recovered cart pays for itself.
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.
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.
Not at all. If you can type a sentence, you can use Callsy. Describe your call in plain English. For Shopify merchants, the integration is point-and-click.
Natural and conversational — not robotic. You choose from multiple voice profiles and customize tone, pace, and personality to match your brand.
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.
Callsy runs entirely server-side. Your API keys, customer data, and call recordings never touch the agent's local environment.
