Connector Documentation

PhoneCallFor.me MCP connector — last updated August 2026

What This Connector Does

PhoneCallFor.me places real outbound phone calls to US numbers on your behalf, using an AI voice agent that speaks naturally, navigates phone trees, and waits on hold. Connected to Claude, it lets you ask for a call in plain language and then follow the live transcript and final summary in the conversation.

How To Connect

Server URL: https://phonecallfor.me/mcp

Transport: streamable HTTP. Authentication: OAuth 2.0 with PKCE and dynamic client registration — no API key or token to copy anywhere.

Before you connect, you need:

A PhoneCallFor.me account — sign up free with Google or Apple at phonecallfor.me.
A credit balance, if you intend to place a call. New accounts start at zero credits, so buy a pack before your first call — see Credits.

To connect:

Add https://phonecallfor.me/mcp as a connector.
You will be redirected to PhoneCallFor.me to sign in with Google or Apple.
Approve access. You are returned to Claude and the six tools become available.

Access lasts 30 days, after which you sign in again. You can revoke access at any time by removing the connector, or by emailing support.

Tools

Six tools, four of which only read data. The two that change something — placing a call and hanging up — are marked as destructive so that Claude asks you before using them.

Start Phone Call writes

start_call — places a real outbound call to a US number and has the AI agent carry out a task. Consumes credits and cannot be undone once connected. Returns an internal call identifier used by the two tools below.

Parameter	Required	Description
`phone`	yes	US phone number, E.164 preferred (e.g. `+15558675309`). Non-US numbers are rejected.
`task_description`	yes	What the agent should accomplish, in plain language.
`context_notes`	no	Caller name, account or reservation number, dates, desired outcome.
`voice`	no	One of 21 voices. Defaults to `aura-asteria-en` (English female); `aura-orpheus-en` is the English male default. Voices ending in `-es` speak Spanish.

Get Call Status read-only

get_call_status — returns the current status, elapsed time, and recent transcript lines for an active or recently ended call. Poll once every 20–30 seconds while a call is in progress. Takes the call identifier returned by start_call.

End Phone Call writes

end_call — hangs up an in-progress call immediately. The call cannot be resumed. Takes the call identifier returned by start_call.

Get Call History read-only

get_call_history — returns your recent calls with date, number dialed, outcome, duration, credits used, and an AI-generated summary. Optional limit parameter, 1–20, default 5.

Get Credit Balance read-only

get_balance — returns your current credit balance. Takes no parameters.

Buy Credits writes

buy_credits — generates a one-time Stripe checkout link, valid for 15 minutes and tied to your account. Takes no parameters. This only creates the link; no card is charged until you complete checkout yourself in your browser. Payment details are entered on Stripe's hosted page and are never seen by this service or by Claude.

Every Call Announces Itself

The AI disclosure cannot be turned off. As soon as a human answers, the agent says it is an AI assistant calling on your behalf and that the call is being transcribed. This is enforced by the service — it cannot be removed or overridden by you, by Claude, or by anything written into the call instructions. If the called party asks to stop, the agent says goodbye and ends the call. If asked directly whether it is a human, the agent must truthfully say it is an AI.

Call audio is transcribed in real time and summarized when the call ends. The audio itself is not recorded or retained by this service.

What This Service Will Not Do

Under the Terms of Service, the following are prohibited, and calls are screened before they are placed:

Telemarketing, solicitation, political calls, robocalling, or mass dialing.
Debt collection, or any purpose regulated under the FDCPA.
Calls to 911, suicide hotlines, or other crisis lines.
Impersonating a specific real person, a government agency, law enforcement, or a financial institution.
Fraud, scams, harassment, threats, or repeated unwanted contact.
Anything violating the TCPA, state telemarketing laws, or wiretapping statutes.

Under the TCPA you are the caller and this service is infrastructure acting on your instruction; you are responsible for having a legitimate reason to contact the person you are calling. Do not use the service to transmit medical records, diagnoses, or test results — see the Privacy Policy for what is and is not appropriate.

Technical limits: US numbers only, and one call at a time per account. A request that fails the pre-call safety screen costs 1 credit, which is deliberate — it keeps probing the screen from being free.

Credits

One credit buys one minute of call time, rounded up to the nearest minute, with a one-credit minimum per connected call. Credits never expire.

Pack	Price	Credits
Starter	$2	10 credits (10 minutes)
Standard	$10	60 credits (60 minutes)

Top up by asking Claude to buy credits (which calls buy_credits), or directly at phonecallfor.me/buy. You can also earn 5 free credits for each friend who signs up with your referral link, shown on your account page.

Privacy

Calls are carried by Twilio, transcribed and voiced by Deepgram, and driven by Anthropic's API. Your name, email, call metadata, and call summaries are stored in your account. Full detail, including retention and deletion, is in the Privacy Policy.

Support

Email support@phonecallfor.me for help, bug reports, account deletion, or billing questions.
