TypoSafe AI — Jef
Server Details
Jef decides. Give it options, it returns one with a confidence, never a sentence. A parody.
The last two health checks of this connector failed. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

Scored across 5 tools
Each tool maps to a distinct decision type: verdict (flag), single choice (pick), ordering (rank), numeric rating (score), and binary answer (yes_no). The descriptions reinforce boundaries with usage examples and explicit exclusions, so an agent should rarely misroute a request.
All tools share the jef_ prefix and use short lowercase action-style names (flag, pick, rank, score, yes_no). The pattern is immediately predictable after seeing one tool.
Five tools is a tight, well-scoped set for a subjective decision-aid server. Each tool covers a distinct common request type without redundancy or padding.
The toolset covers the main subjective decisions a user might ask for: verdicts, choices, rankings, ratings, and yes/no answers. It lacks an open-ended explain/advice tool, but that appears outside the declared purpose of giving structured Jef-style judgments.

- AlicenseAqualityCmaintenanceEnables local, LLM-free probabilistic decisions (choice, classification, scoring, yes/no) with real probabilities in 100+ languages, as a drop-in replacement for jev-local tools.4MIT
- AlicenseNot gradedqualityBmaintenanceAn MCP server that exposes eleven typed decision tools—check, choose, score, judge, route, triage, guard, grep, rank, compact, and ask—so agents can make fast, branchable yes/no, option-pick, score, and filtering decisions on text via TypeSafe's Jev model.12 npm2MIT
- AlicenseNot gradedqualityAmaintenanceExposes three tools over MCP stdio that answer typed questions — yes/no, choice, and score — with calibrated probabilities instead of prose. Runs entirely offline by default, names every transmission before it happens, and only reaches a live Jev provider when credentials and provider settings are supplied.66 npmApache 2.0
