Common questions

Is Quesen Deterministic Agent Decision Layer safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.10.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Quesen — Developer Portal

Quesen is the deterministic decision-and-receipt core for agent actions —

a typed security context in, a PASS / REVIEW / BLOCK / SKIP verdict out, with

machine reason codes and a receipt you can re-run byte-for-byte and prove.

No model inference is in the scoring path, so the same input always yields the

same verdict. It is built to sit behind injection detection, on top of

agent identity, and to bill per decision (ASP/402).

Unlike log-based governance layers whose audit trail is *their word, kept by

them*, a Quesen receipt is independently verifiable by the caller —

recomputable, and (engine signing enabled) Ed25519-signed. See

docs/architecture-gap-closers.md and

client-side enforcement + receipt verification in quesen-sdk ≥ 0.5.0.

Production engine signing is live — verify a real signed receipt yourself in

docs/verify-live-receipt.md (no trust in Senueren required).

This repository is the public developer portal. It contains only

documentation, integration guides, examples, registry manifests, and

reference links. No engine source code lives here. Quesen's engine

implementation is sovereign, non-public infrastructure.

Quick start (30 seconds)

Fastest path — no install, no signup, no card. Self-serve a free sandbox key and run a real deterministic decision against production. Full guide: docs/QUICKSTART.md · try it in the browser at senueren.co.za/try.

# 1 · get a free sandbox key

curl -X POST https://api.senueren.co.za/sandbox/keys

2 · evaluate an action (use the api_key from step 1)

curl -X POST https://api.senueren.co.za/validate \ -H "X-API-Key: sk_sandbox_..." \ -H "Content-Type: application/json" \ -d '{"domain_age_days": 1, "engagement_ratio": 0.95, "scam_keyword_count": 4}'

-> {"decision":"SKIP","risk_score":1.0,"conflict_triggers":[...],"input_snapshot_hash":"..."}

SDKs

Published. The SDKs are live on PyPI and npm (quesen-sdk 0.5.0 / npm 0.5.0;

quesen-langchain, quesen-crewai, quesen-autogen 0.3.0). The

base_url + X-API-Key (including the sandbox key above) are identical across all SDKs.

Python

pip install quesen-sdk   # PyPI: https://pypi.org/project/quesen-sdk/

from quesen_sdk import QuesenClient

q = QuesenClient(base_url="https://api.senueren.co.za", api_key="YOUR_KEY") # a sandbox key from /sandbox/keys works here

verdict = q.validate(domain_age_days=1, engagement_ratio=0.95, scam_keyword_count=4) if verdict.decision == "SKIP": return # respect the deterministic answer

JavaScript / TypeScript

npm i quesen-sdk   # npm: https://www.npmjs.com/package/quesen-sdk

import { QuesenClient } from "quesen-sdk";

const q = new QuesenClient({ baseUrl: "https://api.senueren.co.za", apiKey: process.env.QUESEN_API_KEY, });

const verdict = await q.validate({ domain_age_days: 1, engagement_ratio: 0.95, scam_keyword_count: 4, });

MCP (Claude Desktop, Cursor, Windsurf, etc.)

Quesen exposes five MCP tools over the production endpoint. See docs/mcp.md for the client-config snippet.

Why Quesen?

Autonomous agents make more decisions per second than any human oversight can audit. When those decisions involve capital — launching a token, opening a position, executing a trade, greenlighting a smart-contract deployment — the marginal cost of a bad decision is fatal.

Quesen answers exactly one question:

*Should the calling agent proceed with this action?*

Inputs are typed. Outputs are one of PROCEED, REVIEW, SKIP, always with a risk_score in [0.0, 1.0], a confidence in [0.0, 1.0], and the exact conflict rules that fired. Same inputs → same output. Every time. Every response embeds engine_version, weights, and thresholds. Fully reproducible. Fully auditable.

What Quesen is not

Not an LLM wrapper. No prompts. No probabilities.
Not a chatbot. It is A2A infrastructure.
Not a KYC/identity system. It scores risk, not identity.
Not chain-locked / framework-locked / LLM-locked. Ecosystem-neutral by design.

Evidence & case studies — verified upstream merges + live, byte-for-byte replayable receipts. Engineering/standards evidence only; no customer traction is claimed.

Independent verification

Published receipts are independently reproducible from this repo alone — no hosted service or private engine required:

python3 verify/verify_receipts.py          # offline, stdlib-only

python3 verify/verify_receipts.py --live # also cross-check the live engine

All six UCP #724 vectors show a byte-for-byte three-way match between the published fixture, the public reference, and the live engine (verify/README.md, verify/three_way_match.json). That doc also states honestly where independent verification stops today (the production ruleset commit_sha is not publicly resolvable; receipts are not yet cryptographically issuer-signed).

The egress/authority decision subset — the part security integrators gate on — is now independently *verdict*-replayable offline too, with zero network:

python3 evaluation/conformance/verify_conformance.py   # offline; recomputes decision+reasons+hash

Six cases (OWASP-agentic + LoopX prepared-Effect PASS/REVIEW/BLOCK) recompute byte-for-byte from the public reference evaluator, plus a prod-1→prod-2 integrity-flip check — no signup, key, or hosted call (evaluation/conformance/README.md).
