Unofficial MCP server for Jev, Typesafe AI's System One model. Not affiliated with Typesafe AI.

Give your agent a fast second opinion. It asks a plain question about material it already has, Jev works out whether that is a yes/no, a scale, or a choice, and answers with calibrated probabilities. No generative model in the loop, one round trip, a fraction of the cost and latency of a sub-agent.

Demo

An agent planning a workflow, asking Jev one question at a time. Every number is real.

Install

You need a Typesafe API key. The server runs in one of two places; every client below supports at least one.

  • Hosted. https://jev.zacca.dev/mcp runs this repository on Cloudflare Workers. It keeps

nothing: every call builds a Typesafe client from the key you send and forwards the question. Send the key in the x-api-key header, or as a bearer token if your client only has that field. The same server is listed

Connect

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions

What is the askjev MCP server?

Unofficial MCP server for Jev (Typesafe AI)

What tools does askjev expose?

1 in total: 1 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is askjev safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does askjev need?

It reads TYPESAFE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does askjev run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as askjev at 0.2.0.

How current is this page?

The grade is for one exact copy of the source (95ce69a92492), read on 2026-10-12. The repository is watched and re-audited when it changes.
