## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Endpoint Security**: 11/100
  - TLS not yet verified: we couldn't open a connection to check the certificate.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS not yet verified: we couldn't read the response headers to check for it.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).

  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the Quesen Deterministic Agent Decision Layer MCP server?

Quesen Deterministic Agent Decision Layer is a hosted endpoint at https://web-production-3df26.up.railway.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (5)

### `quesen.validate` (~130 tokens)

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.

Input parameters:

- `client_request_id` (string|null): Optional caller-side trace id (echoed in response).
- `domain_age_days` (integer|null): Age of the target domain in days.
- `engagement_ratio` (number|null): Engagement ratio in [0, 1].
- `scam_keyword_count` (integer|null): Count of known scam keywords detected.

### `quesen.simulate` (~250 tokens)

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

Input parameters:

- `client_request_id` (string|null): Optional caller-side trace id. Echoed verbatim in the response for cross-system correlation.
- `domain_age_days` (integer|null): Age of the target domain in days. Same feature as quesen.validate; combined with the (possibly overridden) weights to produce a counterfactual risk score.
- `engagement_ratio` (number|null): Engagement ratio in [0, 1]. Same feature as quesen.validate; used with the (possibly overridden) weights during simulation.
- `scam_keyword_count` (integer|null): Count of known scam keywords detected. Same feature as quesen.validate; used with the (possibly overridden) weights.
- `thresholds_override` (object|null): Optional decision-threshold override used ONLY for this simulation. When null the engine uses its production thresholds. Does NOT mutate global state.
- `weights_override` (object|null): Optional per-feature weight override used ONLY for this simulation. When null (or omitted) the engine uses its production weights. Does NOT mutate global state.

### `quesen.report` (~360 tokens)

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.

Input parameters:

- `client_request_id` (string|null): Optional caller-side trace id. Echoed verbatim in the response for cross-system correlation.
- `elapsed_seconds` (integer|null): Seconds elapsed between the original quesen.validate decision and the observation of this outcome. Non-negative.
- `notes` (string|null): Optional free-text notes about the outcome (post-mortem, context, references). Stored verbatim for audit.
- `outcome` (string, required): Real-world outcome once known. RUG = rug-pull / total loss; LOSS = negative PnL; OK = neutral / no material result; WIN = positive PnL; UNKNOWN = outcome not yet observable.
- `realized_pnl` (number|null): Realized profit/loss in the caller's chosen unit (e.g. USD, SOL, ETH). Sign convention: positive = profit, negative = loss. Fed into the aggregate `pnl_mean` counter.
- `request_id` (string, required): The `request_id` returned by a prior quesen.validate call. Ties the reported outcome back to the exact decision that produced it.
- `signal_hash` (string|null): Optional hash/fingerprint of the original signal (URL, token address, message id) so outcomes can be joined across systems that don't share Quesen request_ids.
- `venue` (string|null): Venue or platform where the trade/signal was executed (e.g. 'raydium', 'jupiter', 'uniswap-v3'). Free-form label for downstream grouping.

### `quesen.health` (~19 tokens)

Liveness probe. Returns engine_version and transport.

### `quesen.version` (~19 tokens)

Full engine configuration — weights, thresholds, versions.

## Common questions

### What is the Quesen Deterministic Agent Decision Layer MCP server?

Quesen Deterministic Agent Decision Layer is an MCP server listed in the public MCP registry as io.github.Shxnque/quesen. Deterministic decision layer for autonomous agents: reproducible PROCEED/REVIEW/SKIP verdicts. This page covers its hosted endpoint (https://web-production-3df26.up.railway.app/mcp).

### Is the Quesen Deterministic Agent Decision Layer MCP server safe to use?

Quesen Deterministic Agent Decision Layer scores 23 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Quesen Deterministic Agent Decision Layer MCP server expose?

Quesen Deterministic Agent Decision Layer exposes 5 tools: quesen.validate, quesen.simulate, quesen.report, quesen.health, quesen.version. Their descriptions and schemas cost roughly 778 tokens of context every time the server is loaded.

### Does the Quesen Deterministic Agent Decision Layer MCP server require authentication?

Its publisher declares no required credentials for Quesen Deterministic Agent Decision Layer. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Quesen Deterministic Agent Decision Layer MCP server still maintained?

Quesen Deterministic Agent Decision Layer is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 3 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
