Nothing serious here today

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

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add jev -- uvx jev-mcp

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "jev": {
      "args": [
        "jev-mcp"
      ],
      "command": "uvx"
    }
  }
}

~/.codex/config.toml

[mcp_servers.jev]
command = "uvx"
args = ["jev-mcp"]

.cursor/mcp.json

{
  "mcpServers": {
    "jev": {
      "args": [
        "jev-mcp"
      ],
      "command": "uvx"
    }
  }
}

.vscode/mcp.json

{
  "mcpServers": {
    "jev": {
      "args": [
        "jev-mcp"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: TYPESAFE_API_KEY (TypeSafe API key used for Jev judgments). The author declared them in the registry entry; get the values from the project itself.

Jev — questions

Answers built from our own checks of this server.

Why is there no uptime for Jev?

Jev 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 pypi package jev-mcp.

How do I connect Jev?

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-mcp straight from pypi; nothing to host, nothing to sign up for.

Is Jev open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
