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.

Last updated · April 20, 2026

Overview

This Data Processing Agreement (“DPA”) establishes data handling responsibilities between Callsy AI OÜ(“Processor”) and Merchants who use Callsy via the Shopify app, REST API, or Model Context Protocol (MCP) server. It forms an integral part of the Main Agreement between the parties and is incorporated by reference upon account creation or installation of any Callsy integration. No additional signature is required under GDPR Article 28.

1. Definitions

Personal Data: information relating to an identified or identifiable natural person, as defined in the GDPR.
Processing: any operation performed on Personal Data, including collection, storage, transmission, and deletion.

Services: the Callsy AI platform, including the Shopify app, REST API, MCP server, and related integrations.
End User: the natural person the Merchant contacts using the Services.

2. Processing scope and instructions

Processor shall process Personal Data solely to provide the Services — including automated outbound calling, cart recovery, call analytics, and execution of MCP tool calls triggered by the Merchant or by the Merchant’s authorised AI agent.

Processor shall not use Merchant or End-User data for training of general foundation models, without the Merchant’s explicit written instructions.

2.5 AI disclosure obligation

The Merchant shall ensure that all AI Agents configured via the Service disclose their non-human nature to the End User at the commencement of the call, in line with the EU AI Act.

Data categories covered by this DPA include:

Name, phone number, email
Order and cart information (value, items, status)
Lead and prospect status
Call metadata (duration, timestamps, outcome)
Call recordings and transcripts
Voice inputs (not used for biometric identification)

The Merchant shall not submit special categories of Personal Data unless agreed in writing.

4. Processor obligations

Confidentiality: Processor ensures that authorised personnel handling Personal Data are bound by confidentiality obligations.
Security: Processor implements the measures described in Annex 2 (TOMs).
Breach notification: Processor notifies the Merchant without undue delay and no later than 48 hours after becoming aware of a personal-data breach.
Assistance: Processor assists the Merchant with data-subject requests, DPIAs, and regulator consultations.
Deletion: Personal Data is deleted or anonymised within 30 days of termination, unless retention is legally required.

5. Merchant responsibilities

Obtain and maintain a lawful basis for all Processing, including consent where required
Comply with telemarketing, unsolicited-communication, and consumer-protection laws in every market contacted
Secure the Merchant’s own systems, API keys, and MCP credentials
Provide clear, accurate instructions to Processor

6. International transfers

Where Personal Data is transferred outside the EU/EEA, the parties rely on Standard Contractual Clauses and, where applicable, supplementary measures. Sub-processor locations and the specific transfer basis are listed in Annex 3.

7. Audit

Processor makes available to the Merchant, upon reasonable written request, the information necessary to demonstrate compliance with this DPA, including through independent audit reports. The Merchant shall treat any such information as confidential.

8. Term and termination

This DPA remains in force for the duration of the Main Agreement. On termination, Processor shall delete or return all Personal Data in accordance with Section 4.

Processor’s liability under this DPA is subject to the limits set out in the Main Agreement and the Terms of Service. In any event, aggregate liability is capped at the amounts paid by the Merchant to Callsy in the preceding 12 months.
