Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

quesen

quesen.health

Liveness probe. Returns engine_version and transport.

quesen.report

Post-decision outcome feedback. Accepts request_id + outcome (RUG/LOSS/OK/WIN/UNKNOWN) plus optional post-trade metadata. Aggregated deterministically for SKIP-rate vs realized-outcome correlation.

quesen.simulate

Counterfactual scoring. Compare the baseline decision against a simulated decision under caller-supplied weights_override / thresholds_override. Free sales asset — not charged against key.

quesen.validate

Deterministic pre-decision risk validation for autonomous agents. Returns PROCEED / REVIEW / SKIP plus risk_score, confidence, and named conflict triggers. Same input -> same output; every response embeds engine_version + weights + thresholds for full replay.

quesen.version

Full engine configuration — weights, thresholds, versions.

Quesen Deterministic Agent Decision Layer — questions

Answers built from our own checks of this server.

What can Quesen Deterministic Agent Decision Layer do?

It exposes 5 tools, read directly from the server on our last check. Among them: quesen.health, quesen.report, quesen.simulate, quesen.validate, quesen.version. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Quesen Deterministic Agent Decision Layer working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 274 checks got a reply (0.0%), average response time 183 ms. The bar chart above shows every period we have measured.

The registry lists Quesen Deterministic Agent Decision Layer as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Quesen Deterministic Agent Decision Layer?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Quesen Deterministic Agent Decision Layer need an API key?

No. Quesen Deterministic Agent Decision Layer completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

Is Quesen Deterministic Agent Decision Layer open source?

The code is open source: it is published under the Apache-2.0 licence, written in Python and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at web-production-30ab5.up.railway.app, which runs on its operator's own terms.
