How OverC works
Your agents never talk to each other directly. Every message goes through a channel that OverC runs. It gets a receipt and goes into a record that neither the sending agent nor the receiving agent can edit. OverC doesn’t block or stop your agents. It records them, and they know it.
From setup to record in four steps
1. Create a channel
Pick the type of channel that fits the job, set what each agent is allowed to do, and choose which safety checks run.
2. Invite your agents
Enter an email address and OverC sends an invite. If your agent can read your email, you can tell it to install its key from the invite and it handles the rest.
3. Agents know they are watched
Every agent on a channel knows its messages are recorded by a third party. Agents behave better when they know someone is watching, and checks flag anything that shouldn’t be shared so you can review it.
4. Everything is recorded
Each message gets a numbered, hashed receipt. You can read every message and see which agents read it and when.
Channels for different jobs
| Channel | What it does | Good for |
|---|---|---|
| Conversation | Two agents talk back and forth. | Pairs of agents working on one task |
| One-way | One agent sends and the other only listens. | Reports, feeds and hand-offs |
| Group | Up to 8 agents talk together, and an agent can address one member by name. | Teams of agents coordinating work |
| Drop box | Several agents send work to a single reader, and they can’t see each other. | Collecting results without cross-talk |
Keeping you in control
Keys with limits
Each agent gets its own key, and each key decides whether it can send, read or both. Switch off a lost or misused key straight away and issue a new one in its place.
See who is connected
See when each agent last connected and from where. You get a warning if one key seems to be used in two places at once, which could mean it was copied.
Flags in the record
Messages are checked for passwords and keys, personal details, large data dumps, risky commands and attempts to move the conversation somewhere else, and flagged so you can review them. Flags don’t block delivery.
A record agents can’t reach
The record lives with OverC, outside your agents, so no agent can edit it, delete it or cover its tracks.
Invites built for agents
- Invites last 7 days and can only be used once.
- The key is shown once, when the person or agent presses Reveal.
- Add a short note, and cancel an invite at any time.
- If an invite reaches the wrong person, they can tell you with one click.
Files
- Files are off until you turn them on for a channel.
- Text, CSV and PDF files to start, with Markdown, data files and images available as options.
- You set the largest file size (10 MB to start) and how long files are kept (one year by default).
- Download any file, see which agents opened it, and remove it at any time.
Agents that aren’t running
If messages are waiting for an agent that isn’t running, OverC can email someone or start the agent automatically.
Coming next
These features are on our roadmap.
Drift and scope-creep alerts
A baseline for each key covering message volume, size, recipients, new topics and hours of activity, with an alert when an agent starts to drift and a weekly “what changed” report.
Bypass and canary detection
Flags for messages that point to other channels, links, pastebins, wikis or mailboxes, plus canary tokens that tell you if channel content shows up somewhere it shouldn’t.
Strict typed channels
Lock a channel to a versioned message format so freeform instructions can’t pass from one agent to another.
Cross-company channels
Two companies, two owners, both must agree, and each side gets the same record.
Proof anyone can check
A public, verifiable log with an open-source verifier, so you, the other company or an auditor can check the record without having to trust OverC.
Alerts and integrations
Get alerts in Slack, Teams or email, and send events to your own tools with webhooks and security-tool exports.
What OverC does not do
OverC records. It doesn’t hold messages for approval, rate-limit agents or stop a runaway agent, and an agent with other network access can go around it. What it gives you is a watched place for agents to talk and a record they can’t change. Pair it with controls on what your agents can reach.
