Quesen MCP Server

Quesen MCP server exists for a simple reason — assistants are far more useful when they can act on Quesen directly instead of describing what you should do. Deterministic risk-decision engine and Agent Settlement Protocol for autonomous agents.

What you get

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

Setting it up

Installation goes through your MCP client rather than a global install: point it at quesen-sdk on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

What the assistant can call

Once Quesen is connected, these are the calls the assistant has available:

• Production — https://web-production-30ab5.up.railway.app
• JavaScript — Shxnque/quesen-sdk-js
• LangChain — Shxnque/quesen-langchain
• CrewAI — Shxnque/quesen-crewai
• AutoGen — Shxnque/quesen-autogen
• Surface — URL
• Health — https://web-production-30ab5.up.railway.app/health
• Version — https://web-production-30ab5.up.railway.app/version
• Framework — Package
• Tutorials — The Tutorials tool exposed by this server

Configuration and credentials

You will need 2 environment variables: YOUR_KEY, QUESEN_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Quesen.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the quesen mcp server does with a few real requests.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Quesen's toolset — Production, JavaScript, LangChain and 7 more — is a fair guide to whether it matches your workflow. It is maintained by Shxnque; worth a glance at recent repository activity before you build anything load-bearing on it.
