What you can install and use today

Three pieces, all open source. There is no hosted service, no price and no enterprise customer. The products this page used to show (a Delentia Platform for testing, Delentia AI, SignedAI as an API) were not offered as described and have been withdrawn.

Delentia OS

Open-source agent runtime

An agent loop in which every action passes a safety gate, risky actions wait for a human signature, and every episode leaves a signed, hash-chained audit log. Runs on your machine with a local model or your own provider key.

  • Model-free demo: delentia demo run compare --scripted
  • Policy written in plain sentences, shown back before saving
  • Memory you can replay, revoke and erase
  • Optional jury of independent models (SignedAI)
pip install delentia-osGitHub

Delentia Guard

MCP proxy

Sits between an AI client and its MCP tools: every tool call is judged before it runs, and each decision is written to an Ed25519-signed audit log. It runs as a separate process from the agent.

  • Signed audit log you can verify offline
  • Refuses calls that name its own key file or log
  • Apache-2.0
npm i -g delentia-guardnpm

Delentia MCP

Live MCP connector

A connector to a small live MCP gateway running on Cloudflare Workers: six tools including the FDIA gate evaluation, a seven-step reasoning prompt and context compression. It is a gateway for your own model; it has no model of its own.

  • Six tools, 286 passing tests in the connector's CI
  • No SLA and no uptime promise
