Jev decisions (jevmodel.org) tools (4)

Read from the live server on Nov 8, 2026. These are the tools your AI assistant can call once connected.

jev_decide

Ask Jev up to 8 typed questions (choice, score, noul) about one state in a single call. Questions share the state and run in parallel, so ask everything you need at once. Returns typed answers with calibrated probabilities.

jev_noul

Ask Jev a single yes/no question about a state. Returns noul — a calibrated probability between 0 and 1 that the answer is yes. Use for gates, filters, guardrails and escalation checks.

jev_choice

Ask Jev to pick one of a set of labelled options for a state. Returns the winning key, per-option probabilities and a confidence. Use for routing, classification and triage.

jev_score

Ask Jev to place a state on an ordered scale. Returns a fractional score (the probability-weighted mean of the levels), the distribution and a confidence. Use for rubric scoring, severity and prioritisation.

How to connect Jev decisions (jevmodel.org) to Claude, Cursor or VS Code

Claude Code: claude mcp add --transport http jev-decisions-jevmodel-org https://jevmodel.org/mcp. VS Code's .vscode/mcp.json uses a servers key instead of mcpServers (see how). Servers that require OAuth or an API key will prompt on first use.
