io.github.Shxnque/quesen MCP Server

This Model Context Protocol (MCP) server provides access to a deterministic risk-decision engine and an Agent Settlement Protocol for autonomous agents. It is positioned for developer use across agent-to-agent and autonomous-agent workflows, with emphasis on risk evaluation and settlement processes.

🛠️ Key Features

Deterministic risk-decision engine
Agent Settlement Protocol for autonomous agents
MCP server integration
Support reflected in topics: risk-evaluation, deterministic, agent-to-agent, a2a

🚀 Use Cases

Risk evaluation in autonomous agent systems
Agent-to-agent settlement using an Agent Settlement Protocol
Integration with agent frameworks indicated by topics (e.g., langchain, crewai, autogen)

⚡ Developer Benefits

Aligns with Model Context Protocol (mcp) development workflows
Encourages deterministic behavior for risk decisions
Relevant for onchain settlement contexts indicated by topics (onchain, usdc)

⚠️ Limitations

Public data provided does not list specific tools, interfaces, or implementation details.

Quesen — Developer Portal

Quesen is the deterministic AI decision engine for A2A (Agent-to-Agent) risk evaluation. It is the trust filter that sits between autonomous agents and capital loss.

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)

Python

bash

pip install quesen-sdk

python

from quesen_sdk import QuesenClient

q = QuesenClient(base_url="https://web-production-30ab5.up.railway.app",
                 api_key="YOUR_KEY")

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

bash

npm i quesen-sdk

import { QuesenClient } from "quesen-sdk";

const q = new QuesenClient({
  baseUrl: "https://web-production-30ab5.up.railway.app",
  apiKey: process.env.QUESEN_API_KEY,
});

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

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.
