Governed AI agents

AI agents for sensitive data and business-critical apps

Minerva is an agent for work with sensitive data and business-critical apps. While other agents get broad access and are asked to behave, Minerva’s access is set per folder, channel and customer and enforced by a gateway, and the agent never holds a key.

Why Minerva

Most agents are given the keys and asked to behave

In Minerva the keys stay in a gateway that checks every call, so a model that has been misled can still only use the access you granted.

What the agent can reach is limited by rules the model cannot change.

How it works

Every action is checked against your rules before it reaches an app

When an agent tries something you haven’t allowed, the action is refused and you see the reason in the conversation.

Four actions an agent might try

The agent is told the reason too, so it can tell you or try another way.

Each answer runs in a new, sealed container

Minerva checks the container before agents use it.

No access to the server it runs on or to Minerva’s database

The agent never holds a key

Minerva keeps your keys and makes each call for the agent once it passes the checks.

Permissions

Access is set per resource, using the structure each app already has

You choose the labels, folders, channels, teams and customers an agent may use, and what it may do with each of them.

Grant actions per team, and sub-teams inherit them

Anything you leave unticked is invisible to the agent.

Security

What still holds when an agent is tricked

Models sometimes follow instructions hidden in emails or web pages. In Minerva such an instruction still meets your rules.

An email asks the agent to send your invoices to a stranger

Models and hosting

Use the model you trust and run Minerva where you need it

Pick a model provider you already use, or run a model yourself. Minerva can run on your own machines too.

Choose where the model runs

Minerva asks the provider not to store your requests.

A hosted provider
OpenAI, or any other provider with an OpenAI-compatible API.
Your own servers
An open-weight model served with vLLM or Ollama, so prompts stay in your network.

Self-host it under the MIT licence

Run it for free on a laptop, a server or in your own data centre, with the same checks as the hosted version.

git clone https://github.com/minervacomputing/harness
cp .env.example .env
make setup && make dev

Runs on Docker or Podman. The README explains how to connect your apps.

Comparison

How Minerva compares with other agent products

Minerva is younger than these products and connects to fewer apps. It differs in how access is granted and enforced.

About

Who is building Minerva

I’m Szymon Nastaly, and I build AI agents for code review and security testing. One is a pull-request review agent used by more than 160 developers, another a multi-agent system for penetration testing. I’m studying computer science at ETH Zürich, with a focus on security. I started Minerva because I wanted agents to work in company systems without handing them the keys.

I write about what I learn from building with agents in This Week in Agents.

FAQ

Questions people ask before trying Minerva

Is Minerva open source?

Yes. All of it, including the gateway, the sandbox and every connector, will be published under the MIT licence, and the self-hosted version has the same security model as the hosted one.

Which models can I use?

Any model behind an OpenAI-compatible API, through the Responses API or Chat Completions. That covers the major providers and open-weight models on your own hardware.

How is this different from approving each action?

Approval prompts rely on someone reading every request, and the agent keeps the keys while it waits. In Minerva you set the rules ahead of time and the gateway refuses anything outside them; approval for single actions is planned as an addition.

Can agents run on a schedule or be reached from Slack and Teams?

Not yet. Both are the next items on the roadmap, and they will go through the same gateway and checks as a conversation.

Can I connect MCP servers or install community skills?

Not at present. A generic MCP server does not tell the gateway which folder, channel or customer a call will touch, so it could only be allowed or denied as a whole.

Where are my credentials stored?

Encrypted at rest in PostgreSQL with versioned keys, readable only by the backend. They never reach the agent’s container or the browser.

Is it only for companies?

It is designed for teams that need to control what agents can reach, but it works just as well for one person, and the self-hosted version runs on a laptop.

Is it ready for production use?

It is early. The permissions, the sandbox and the connectors work against live accounts, while team workspaces, the audit log and the hosted service are still being built.

What will the hosted version cost?

Pricing has not been decided. People on the waitlist will hear about it first, and self-hosting is free under the MIT licence.

Waitlist

Join the waitlist for the hosted beta

The hosted version will open to a few teams first, so we can work closely with them on the permissions and connectors they need. We will email you when there is a place.

If you would rather run Minerva yourself, the source and setup instructions are on GitHub.
