For developers

Ask for a verdict before you act.

One call, from wherever the action originates: an agent's tool call, your own function, a pipeline step, or plain HTTP. You get ALLOW, ESCALATE or BLOCK, and a signed Decision Dossier explaining why.

Quickstart Try to break it — no account

Choose your path

Wherever the action originates, the call is the same shape and the answer is the same verdict.

Application code

Ask from your own function.

Check a dossier without trusting us.

Where Decionis sits in your stack

Decionis does not replace the model, the protocol, or the tool. It is the authority check between the intent and the effect.

Any agent. Any tool. Any system. One consistent decision before anything happens.

Ways in

The protocol reached directly — from an agent's tool call, your own code, a pipeline, or plain HTTP. This is the shortest path from nothing to a first verdict.

MCP Server

Every tool call an agent makes can ask Decionis before it runs.

SDKs

Every function in your own code can ask Decionis before it commits.

GitHub Action

Every deployment can ask Decionis before it ships.

CLI

Every command in a terminal or a pipeline can ask Decionis before it executes.

Webhooks

Every system you already run can ask Decionis over plain HTTP.

Zapier, Make & n8n

Every automation step can ask Decionis before it fires.

What is public today

Everything on this list resolves without an account or a conversation. We list it explicitly rather than gesturing at a GitHub org, because the point of this section is that you can check it.

Ask

@decionis/sdk

package

Ask the hosted protocol for a verdict on a proposed action from your own code, and read the Decision Dossier that comes back.

npm install @decionis/sdk

Verify

@decionis/verify

package

Check a Decision Dossier's Ed25519 signatures against our published JWKS, offline. Node's built-in crypto, no runtime dependencies, and no Decionis account — the verdict does not depend on us being reachable or honest.

Is Decionis open source?

The protocol implementation is not open source today. What is public is exactly the list above — nothing else is on npm or in a public repository yet. The Decision Dossier format is documented and independently verifiable against our published JWKS, so you can check a verdict without trusting our code.

Go deeper

API reference

Every endpoint, every field of the decision contract, and the shape of a Decision Dossier.

MCP integration

Put the decision layer on an agent's tool-call boundary so no tool runs unevaluated.

Policy encoding

Turn written authority into executable rules, versioned and pinned so decisions reproduce.

Policy Exchange

Fork a decision recipe someone else already runs instead of authoring from scratch.

Webhooks

Reach the protocol from any system that can make an HTTP request.
