Mitra, an AI phone assistant, launched Mitra MCP on 10 November so that other AI agents can place calls through it from the user’s own number. Its pricing page lists the Pro plan at $30 a month with 5 call hours, which works out to $6.00 per included call hour, by our arithmetic.
The same day, Fish Audio introduced Live 3, a full-duplex voice model that TestingCatalog described as built for AI agents that operate phone calls. Mandava wrote that “Most agents can’t make calls”.
Business Pill · AI Agents Explained
An evergreen Business Engineer explainer on AI agents. It teaches the general idea only and does not discuss Mitra or Fish Audio.
The key insight: Mitra MCP lets agents such as Claude and ChatGPT place calls from the user’s own number. Mitra’s Pro plan is $30 a month with 5 call hours, or $6.00 per included call hour, by our arithmetic. Fish Audio says its new Live 3 model can decide to respond in as little as 186 milliseconds.
Sai Mandava of Mitra wrote on X: “We’re launching Mitra MCP to give your AI agents access to your personal phone line”. He added: “Your agent calls from your personal number, so people actually pick up”.
Mitra’s MCP page says users can “Connect Mitra to your AI app to make and answer calls from your number”. Its examples show Claude, ChatGPT and Grok asking Mitra to book a table, compare plumbers’ quotes and book a dentist appointment. TestingCatalog reported that, after setup, ChatGPT or Claude can instruct Mitra to make calls.
Mitra itself launched on 23 September as a personal assistant that makes and answers calls from the user’s own number, TestingCatalog reported. The MCP launch came 48 days later, by our arithmetic.
Mitra’s monthly plan prices divided by the call hours each plan includes, from its pricing page read on 10 November 2026. The per-hour figures are our arithmetic; the page does not state overage billing.
What Was Posted on X
Mitra now offers MCP support, allowing other agents to make calls using your own phone number. After a simple setup, users can enable ChatGPT or Claude to instruct Mitra to make phone calls on their behalf.
Mitra is an AI agent that can operate phone calls natively and is also available as a standalone app on iOS, Android, and macOS.

Fish Audio has launched Live 3, its latest duplex voice AI model built for AI agents that operate phone calls.
Live 3 can distinguish a pause in the middle of reading a phone number from the end of a question. Live 3โs current reaction speed is under 200 milliseconds and uses a separate model to prepare the full answer in parallel.

TestingCatalog posted that Fish Audio launched Live 3, a duplex voice model built for AI agents that operate phone calls, with a current reaction speed under 200 milliseconds. The piece uses the 186-millisecond figure from Fish Audio’s own announcement.
What a Call Hour Costs
Mitra lists three self-serve plans with monthly prices. Pro is $30 with 5 call hours, Premier is $90 with 20 call hours and Prime is $300 with 80 call hours. Per included hour, that is $6.00, $4.50 and $3.75, by our arithmetic. Every plan lists unlimited parallel calls, and yearly billing saves 17%, according to the page.
New users get a 7-day free trial with 2 hours of calls, Mitra says. TestingCatalog reported in September that the business model is a subscription, with no advertising or sale of user data.
Fish Audio’s Live 3 Works on the Timing
Fish Audio’s announcement describes Live 3 as its full-duplex voice model: “It keeps listening while it speaks”. The company says Live 3 “can decide to respond in as little as 186 milliseconds”, using short reactions such as “mm-hmm” while the full answer is prepared.
The company says it trained the model on real human conversations, so it learns when to acknowledge, wait, respond or stop. CEO Rissa Cao said: “The fix so far has been more rules and more thresholds”. Live 3 speaks English, is available on the Fish Agent Platform and the API, and can be deployed on-premises, Fish Audio says.
As we read it, the two launches cover different layers of the same job: Mitra supplies the phone line and the call handling to other agents, while Fish Audio sells the voice model that manages turn-taking. Neither company disclosed usage figures, so the scale of either is not established.

“We think a model should learn this from real conversations, the same way language models learn grammar”
Three Implications
FOR AGENT BUILDERS Mitra’s MCP page shows Claude, ChatGPT and Grok asking Mitra to book tables, compare quotes and book appointments.
FOR PRICING Mitra’s included call hours cost $6.00 on Pro, $4.50 on Premier and $3.75 on Prime, by our arithmetic; every plan lists unlimited parallel calls.
FOR VOICE MODELS Fish Audio says Live 3 speaks English today and is available on its agent platform and API, with on-premises deployment for enterprises.
The framework reads: “The unit of interaction is no longer a prompt, but an autonomous workflow.”
As we read it, a phone call placed by an agent is one such workflow: Mitra’s examples show an agent calling several plumbers and returning two quotes for the user to choose from. The framework predates these launches and does not discuss Mitra or Fish Audio.
What Is Not Established
Neither company disclosed user numbers or call volumes. Mitra’s per-hour figures are our division of its plan prices; the page does not quote a per-hour rate or say how overage is billed. Fish Audio did not publish a price for Live 3 in the announcement we read, and its 186-millisecond figure is the company’s own, not an independent test.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
Mitra now lets Claude, ChatGPT and other agents place calls from a user’s own number, starting at $30 a month for 5 call hours, or $6.00 per included hour by our arithmetic. Fish Audio’s Live 3 targets the timing of those calls, with a stated reaction time as low as 186 milliseconds.
A note on sourcing. Mitra facts are from Sai Mandava’s X post and its MCP and pricing pages, read on 10 November 2026, with TestingCatalog’s reporting attributed. Live 3 facts and quotations are from Fish Audio’s announcement of 10 November 2026. Per-hour prices and the day count are our arithmetic. We did not contact either company.
