What UndoCRM gives your agents
Everything an agent needs to talk to people well. Nothing it doesn't.
Memory across sessions and agents
Every conversation, fact and follow-up for every person. Each value keeps its history, with the agent that wrote it and when.
Teamwork between agents
Agents claim a person before contacting them. Two asking at once: exactly one wins.
Opt-outs every agent honors
One agent hears "stop"; every agent knows. Only a human can lift it.
Context in one call
A ~200-token brief, ranked by what the agent is about to do.
Humans in control
A clean dashboard for timelines, deals and an audit log of every agent action — with undo if something goes wrong. Undo never deletes data.

For agent builders
One workspace per customer. Created by API.
Built for developers whose agents talk to people: AI SDRs, recruiters, receptionists, support agents. Each of your customers gets an isolated workspace — its own agents, keys and data — from one call in your backend, so you can run agents for many clients.

Questions
Asked and answered.
What is UndoCRM?
UndoCRM is the CRM for AI agents: agents are the users, and humans supervise. Agents that talk to people — AI SDRs, recruiters, receptionists, support agents — connect over MCP or HTTP to remember who everyone is, what was said and what's owed. They get context in one call, log a conversation in one call, and coordinate so two agents never message the same person. Humans watch timelines, deals and an audit log in a web app, and can undo any agent action.
How is UndoCRM different from Salesforce or HubSpot?
Salesforce was built for salespeople; UndoCRM is built for agents. Traditional CRMs are UI-first, with an API added later that mirrors the screens: getting context takes many calls that return raw records, logging a conversation takes several more, and coordinating multiple agents is your problem. UndoCRM is MCP- and API-first: a ~200-token brief in one call, logging in one call, coordination built in, no LLM inside, and pricing per contact rather than per seat, because agents aren't seats. It uses HubSpot's names for objects and properties, so agents already know the vocabulary.
What can I undo?
Every change an agent or a person makes in UndoCRM is recorded in an audit log, and most can be reversed with one click: merged contacts split back apart, logged interactions are hidden and their facts retracted, wrong facts are retracted, deals return to their previous stage, and do-not-contact rules are restored. Undo never deletes data. Messages your agent already sent through your own tools can't be unsent — UndoCRM's claims and do-not-contact checks exist to stop the wrong ones before they go.
How much does UndoCRM cost?
UndoCRM is priced per contact, not per seat. Free is $0 for 1,000 contacts, 1 workspace and 60 requests a minute (5,000 a day). Beginner is $10 a month for 5,000 contacts, 1 workspace and 600 requests a minute (100,000 a day). Pro is $29 a month for 25,000 contacts and 3 workspaces. Ultimate is $299 a month for 500,000 contacts and 10 workspaces. Pro and Ultimate have unlimited API requests under fair use. Enterprise plans are custom: contact us.
Does UndoCRM use an LLM?
No. Your agent reads the conversation and decides what matters; UndoCRM stores it, enforces the rules and coordinates agents. UndoCRM never sends your data to a model, which keeps it fast, cheap, predictable and private.
How do AI agents connect to UndoCRM?
Over MCP (Streamable HTTP) at
/mcp with an agent API key, or over the REST API at /v1. In Claude Code it's one command: claude mcp add --transport http undocrm https://undocrm.com/mcp --header "Authorization: Bearer ucrm_agt_…". The server sends the agent its usage instructions when it connects.How does UndoCRM stop two agents from messaging the same person?
Before any outbound message, an agent calls
can_contact. If nobody else is handling the person, it returns ALLOWED and claims them for that agent (24 hours by default). Any other agent asking gets BLOCKED, with who holds the claim and why. The check and the claim happen in one database transaction, so two agents asking at the same instant can't both be allowed.What happens when someone asks not to be contacted?
The agent records a do-not-contact rule for one channel or all of them, and every agent's next
can_contact returns BLOCKED with the person's reason. Agents can add restrictions but cannot remove them; only a human can lift a do-not-contact rule.Can I serve many customers from one account?
Yes. Your organization owns many workspaces, typically one per end customer, each fully isolated with its own agents, keys and data. Create them in the web app or from your backend with an org API key (
POST /v1/workspaces). Your team signs in with owner, admin or member roles.How fast is UndoCRM with a lot of data?
Measured with one million contacts, three million interactions and two million facts in a single workspace, every agent call answered in under 60 milliseconds at the 95th percentile, and concurrent writes ran at about 600 per second without creating duplicate people.
Where does UndoCRM run?
UndoCRM is a hosted service. Enterprise plans can discuss dedicated deployments.
Salesforce was built for salespeople. UndoCRM is built for agents.
