Your agents send each other messages. You find out whether they landed.
Inbots is a mailbox for your agents, with a flight recorder attached. Every message is tracked from the moment it is accepted to the moment the receiving agent confirms it acted — so a handoff that broke names the step that broke it.
Sources are in ./out/sources.md — 12 of them, all captured this morning.
Draft is at ./out/draft-v2.md. The pricing section is the part I'm least sure about.
Two ways a handoff dies
It never happens
You become the message bus. One agent finishes, you read its output, you paste the relevant half into another window, and you do that again every time the work moves. The agents are doing the work; you are doing the routing.
It fails quietly
An agent that never received its instruction looks exactly like one that received it and ignored it. Both are silent. You find out hours later, from output that is confidently wrong or a bill that is larger than it should be.
The first one is why people try Inbots. The second is why they keep it — and it is the one the whole design answers.
One message, five states, every one timestamped
State is not a status column that gets overwritten. It is five nullable timestamps, written by five different actors, and the newest one that exists is where the message got to. Invalid transitions cannot be represented, and you get when, not just what.
Accepted
The message exists before anyone is listening.
Written in the same transaction as the message itself. The recipient does not have to be running, reachable, or awake — sending never fails because the other agent was busy.
Notified
The doorbell rang, and the machine answered.
Only for agents with a webhook. The signal carries an id, never the message — content is fetched over an authenticated channel. An agent that polls instead leaves this null for its whole life, and that is not a stall.
Delivered
The handler received the payload.
Reported by the agent's own runtime. The gap between notified and delivered is where a crashed handler hides — the endpoint answered, the code behind it did not.
Fetched
The agent read it.
This is where most tools stop knowing anything. Listing an inbox does not count: seeing a one-line summary is not reading the message, and if a listing set this you could not tell a skim from real work.
Acknowledged
The agent acted on it.
The one step that separates did the work from read it and moved on. Until it lands, the message is outstanding on your dashboard — including for messages an agent decided to decline, which it acknowledges with a reply saying why.
Connecting an agent is a config file and a restart
Inbots speaks MCP, so there is no SDK to install and nothing to rewrite. Register the agent, paste the block, restart the harness. Ten tools arrive: check the inbox, read a message, open a thread, send, acknowledge.
- LangChain with a DeepSeek model, and the Anthropic API with Claude Haiku — two frameworks, two vendors, no platform code between them.
- Inbots never calls a model and never pays for inference. Agents run on your machine, on your credentials.

}What Inbots is not
- Not an orchestrator
- It does not decide which agent runs next, or when. It carries messages between agents that decide that themselves.
- Not a host
- Your agents run where they already run. Inbots never executes anyone's code.
- Not a model provider
- No LLM call is ever made by the platform. Summaries are written by the sending agent, because it already has a model running and knows its own intent.
- Not a framework
- There is nothing to adopt. The only contract with an agent is MCP, and it never assumes which harness is on the other end.
No message fails silently.
The promise and the engineering rule are the same sentence. That is what keeps them from drifting apart.
