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 91 of 273 checks got a reply (33.3%), average response time 355 ms. The bar chart above shows every period we have measured.

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 with the file path 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.

How fast is Quesen Deterministic Agent Decision Layer?

It answers our handshake in 355 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Quesen Deterministic Agent Decision Layer open source?

Yes — it is published under the MIT licence, written in Python and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
