Ask who last called a customer in JustCall, what happened and what was texted.
Connect JustCall with an API key and secret, and Memtro reads calls with outcome, agent, contact, notes and the JustCall AI summary, SMS conversations, and the team's contacts. Only the last three months of calls and texts are available. It reads on demand and there is no hourly sync. When you ask, and once an administrator has granted the action by name, it can text a contact, have an AI voice agent phone a consenting contact, update call notes, manage contacts and tag SMS conversations. Texts and calls reach people outside the company and are charged.
Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right JustCall tool, reads what it needs, and answers with the source cited.
These tools change something in JustCall. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.
Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with JustCall for you. Each event can start a job, with the event as its input. JustCall signs every delivery, and one whose signature does not check out is refused before it is read.
Events and webhooksOnce JustCall is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.
Who called from Acme this week, and what happened on each call?
Which calls did we miss yesterday?
What did we text the Brightwave Ltd contact last month?
Who does the number +44 20 7946 0123 belong to?
Text Dan Fletcher at Northwind that his engineer arrives at 10:00 tomorrow
An account manager is about to call Acme back. She asks Memtro who spoke to them last. It reads the recent calls with that number, giving the agent, outcome, duration, the agent's notes and the JustCall AI summary of the last conversation.
Priya Sharma asks Memtro to text Dan Fletcher at Northwind that the engineer arrives at 10:00. Memtro shows the message, and once she approves it, sends it from the team's JustCall number, where every agent on the line sees it in the thread.
The teams that lean on JustCall most, a question each of them asks, and what they connect beside it.
A record in JustCall is rarely the whole story. Connect the systems that hold the rest and Memtro checks them together, then remembers what it learned so the next question starts further along.
Using something else for the same job, or both? Each connector has its own tools; connect as many as you like.

Ask who called from Acme this week and what the agent noted
Chat in the dashboard, the OpenAI-compatible API, scheduled jobs, and any MCP client: Claude Code, OpenCode, Cursor, Claude Desktop. The JustCall tools are the same everywhere.
Only when you ask, and only what it has been granted: create a contact in JustCall; send an SMS or MMS from a JustCall number to a contact; set the notes, disposition or rating on a finished JustCall call; update a JustCall contact's name, email, company, address, extension or primary number; delete a JustCall contact; have a JustCall AI voice agent phone a contact who has given written consent; create a JustCall SMS tag; tag a JustCall SMS conversation. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded.
API key and API secret. JustCall's API needs the Team plan or higher, and Team allows 30 requests a minute, Pro 60 and Business 90.
Yes. Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with JustCall for you. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
Seven-day free trial, then one monthly price per organisation. Connectors, jobs and memory are never metered.
