Calling and texting MCPs
Calling and texting MCPs aren't for AI cold calling. Real estate teams use them to send texts and emails, pull call recordings and log calls.
What these servers do
Depending on the server, the AI can:
- Draft a text or email, and send it once you approve
- Read a conversation thread before replying
- Pull a call recording or its transcript
- Log a call's outcome ("left voicemail", "not interested", "call back Tuesday")
- Report on calls: how many, by whom, with what results

Can and can't
| The AI can | The AI can't (or shouldn't) |
|---|---|
| Draft texts and emails in your voice | Place a live call and talk to a seller by itself through these servers |
| Send them, after your approval and with consent in place | Text people who haven't opted in |
| Build the list of who to call next | Decide on its own who to contact |
| Pull recordings and summarize them | Get around opt-outs or do-not-call rules |
| Log outcomes and set the next task | Register your number for texting (that's a carrier process) |
What AI can't do: place a live call
No server on this page should have the AI cold-call sellers alone. The live call still happens in a dialer, with a person on it.
AI voice agents exist, but they carry their own consent and disclosure rules. These MCPs work around the call: lists, recordings, logs and follow-up.
RingCentral
RingCentral runs an "MCP Hub" in its labs, and its Team Chat connector is in Claude's connector directory. As of November 2026, we couldn't confirm which calling and SMS actions its MCP servers expose.
Twilio and community servers
Twilio's official MCP server exposes its APIs, including SMS and voice, and is in Claude's directory. It's a developer tool.
Goliath
Goliath keeps messages and call records with your contacts and deals.
- Texts. The AI drafts and sends texts to opted-in contacts.
- Emails. The AI drafts and sends emails from your connected account.
- Calls. The AI builds call lists, pulls recordings, logs outcomes and reports team call stats. The call itself happens in Goliath's dialer, with your team on the phone.
A prompt that runs against Goliath:
"Pull the recording of my call with the owner of 88 Pine Street yesterday and summarize what she said about timing."
Consent, opt-outs and A2P 10DLC
An AI-written message follows the same rules, and the sender is responsible.
- Consent. Marketing texts generally need prior consent under the TCPA.
- Opt-outs. When someone replies STOP, their texts must stop right away.
- A2P 10DLC. To text from a regular US business number, register your brand and campaign with the carriers.
- Do-not-call. DNC rules apply to calls too.
This isn't legal advice, so ask a TCPA lawyer if you're unsure. For what to let an AI send, see MCP security.
One opt-out record across tools
Separate MCPs hide a risk. If texts and calls run through different tools, a STOP in one has to reach the other.
With one system, an opt-out lives on one contact record every channel checks. We count this cost on the cost page; see also CRM MCPs and the follow-up workflow.
Questions
Can AI cold-call sellers for me? Not through these MCP servers, and AI voice agents carry their own consent and disclosure rules.
Will the AI send a text without asking me? No: Claude and ChatGPT show each send first, and Goliath keeps AI texting off until an admin turns it on.
Do I need my own Twilio account to text from Goliath? No: texting runs through Goliath, and plans include texting credits for opted-in contacts.
