Nothing serious here today

Today is the operative word: we check Jev Decision MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: TYPESAFE_API_KEY (Your TypeSafe API key from console.typesafe.ai), TYPESAFE_DEFAULT_MODEL (Default Jev model), JEV_TIMEOUT_MS (Total request deadline in milliseconds, including retries (1–120000)). The author declared them in the registry entry; get the values from the project itself.

Jev Decision MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Jev Decision MCP?

Jev Decision MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package jev-decision-mcp.

How do I connect Jev Decision MCP?

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 runs locally, so the command pulls jev-decision-mcp straight from npm; nothing to host, nothing to sign up for.

Is Jev Decision MCP open source?

Yes — it is published under the MIT licence, written in TypeScript and 1 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.
