WorldMonitor
88.2kGitHub stars
Real-time geopolitical intelligence dashboard that uses TypeSafe Jev questions to score news headline severity into five threat levels and categorize events across 14 conflict, cyber and infrastructure domains, alongside news aggregation and a Country Instability Index.
Jev Integrations & Adapters#community#osint#geopolitics
Communitykoala73/worldmonitorTypeScript
Minutes
1.5kGitHub stars
An MIT-licensed, local-first conversation memory app that transcribes meetings, calls and voice memos on-device into Markdown you own. Its live voice path runs evaluations through Jev, and 34 MCP tools plus a 58-command CLI let coding agents query the history you choose to share.
Jev Integrations & Adapters#community#mcp#transcription
Communitysilverstein/minutesRust
openrouter-jev-mcp
3GitHub stars
A Python decision gateway and stdio MCP server that exposes Jev through OpenRouter's alpha decisions endpoint. Five tools cover yes/no checks, classification, scoring, multi-question evaluation and health, with bounded retries, validated answers and local diagnostics.
Jev Agents & MCP#community#mcp#openrouter
Communityctmx/openrouter-jev-mcpPython
sortwell
0GitHub stars
MCP server and Claude Code plugin that files each captured note, link or meeting line with one Jev request: kind, project, action and duplicate questions answered in parallel. Routes to a project only at 0.45 or above, marks a duplicate only at 0.70 with a matching item, and stores text verbatim in append-only JSONL.
Jev Agents & MCP#community#mcp#note-taking
Communitydharun-cohere/jev-sortwellTypeScript
kNES
34GitHub stars
Kotlin NES emulator whose agent plays Super Mario Bros. and Final Fantasy through typed decisions. Each turn becomes one Choice over goals that can actually run, wired through SemIf against a local Qwen3.5-4B, so a button the game does not offer is never an option; 900 logged decisions never answered off-menu.
Jev Demos & Experiments#community#emulator#gaming
CommunityArturSkowronski/kNESKotlin
Harness Router
21GitHub stars
MIT-licensed Python tool router for coding agents that keeps obvious calls on a fast path, asks Jev (default typesafe/jev-1.13 via OpenRouter) for genuinely ambiguous choices, and can run bounded MCTS when multi-step consequences matter. Ships a CLI, MCP server and hook integrations.
Jev Tools & CLIs#community#routing#mcp
CommunityProtocol-Lattice/harness-routerPython
x402check
10GitHub stars
x402 risk-check provider that scores agent counterparties before payment: OFAC, phishing and drainer feeds, transaction simulation, drainer-kit fingerprints and a Jev model reading context for injected instructions, issuing an ES256-signed attestation per verdict.
Jev Integrations & Adapters#community#x402#payments
Communitycaiovicentino/jev-risk-check-providerTypeScript
Public Browser
18GitHub stars
MCP server that lets Claude Code, Cursor and other clients drive Chrome over the DevTools Protocol, exposing an accessibility-tree menu of stable refs. Its example Jev loop has Jev pick browser actions from that menu, and the README reports about a third fewer tokens and a quarter fewer tool calls in a blind benchmark.
Jev Agents & MCP#community#mcp#browser-automation
CommunitySilbercue/public-browserTypeScript
jev-judge
1GitHub stars
Python CLI that runs declarative YAML, JSON or JSONL test suites natively on Jev Noul, Choice and Score decisions for RAG faithfulness, hallucination detection and agent safety, with watch mode, parallel batching, a pytest plugin and GitHub Actions PR reporting.
Jev Benchmarks & Evaluations#community#cli#ci-cd
Community00200200/jev-judgePython
Oko
9GitHub stars
Local code search for coding agents: ripgrep and BM25 shortlist function-level chunks, Jev Noul relevance questions run across parallel requests, and accepted excerpts return to Codex, Claude Code, OpenCode or Pi through MCP or the `oko ask` command.
Jev Agents & MCP#community#mcp#code-search
Communitybartlomein/okoRust
AgentScope
33kGitHub stars
Alibaba's multi-agent platform, which implements native TypeSafe Jev classification through JevClassifierModel for binary, choice and score routing across agent pipelines. Python 3.11+, Apache-2.0, with a FastAPI agent service and web UI.
Jev Integrations & Adapters#community#multi-agent#framework
Communityagentscope-ai/agentscopePython
BrowserClaw
32GitHub stars
Chrome MV3 extension plus a local MCP server exposing 50 browser tools; its chrome_act_toward_goal micro-loop uses TypeSafe Jev System One or a local decider to pick the next action on an 85%+ pruned, Shadow-DOM-pierced DOM tree, dispatching trusted CDP events in logged-in Chrome without stealing focus.
Jev Agents & MCP#community#mcp#browser-automation
CommunityGoldenLoaf24h/browserpawTypeScript
pi-verdict
13GitHub stars
Permission gate extension for the pi coding agent: deterministic allow/deny rules and protected paths settle clear cases first, then gray-zone tool calls get one structured classify() verdict; Jev is an optional native classifier via TypeSafe direct, OpenRouter, or other gateways, failing closed on error.
Jev Tools & CLIs#community#guardrails#permissions
Communityjesset/pi-verdictTypeScript
r2r-jev
1GitHub stars
Agent governance integration where Jev judges two Noul checks per tool call (beyond scope, destructive), an admission policy decides which judgments may become evidence, and admitted evidence degrades Trust, Delegation and Authorization in persistent R2R relation state.
Jev Integrations & Adapters#community#governance#agent-security
CommunityThneoly/r2r-jevRust
metajev
1GitHub stars
Python library that records each Jev-class decision as the full distribution under a sha256 key of state, question, provider and model, then applies a separate policy. Thresholds, review bands, routing and budgets can change across the recorded history without new model calls.
Jev Repos & SDKs#community#calibration#policy
CommunityYYTbit/metajevPython
jev-harness-lab
3GitHub stars
Evaluation scripts, MCP tools, and a skill router built to measure where jev-1.13.0 fits in agent harnesses, with raw results under eval/.
Jev Benchmarks & Evaluations#community#evaluation#agents
CommunityAitejiu/jev-harness-labPython
Ollaya
1.3kGitHub stars
A local daemon that pulls open decision models and serves them on TypeSafe's /v1/systemone, so a Jev client switches hosts with TYPESAFE_BASE_URL.
Jev Models & Reimplementations#community#rust#open-models
Communityollaya-dev/ollayaRust
System One Connector
349GitHub stars
A single-binary MCP tool named evaluate that sends Noul, Choice, and Score questions to hosted Jev or a local System One server.
Jev Agents & MCP#community#go#mcp
Communityitsmostafa/system-one-connectorGo
jev-code
45GitHub stars
Five typed tools — classify, check, score, rank, and ask — plus a skill, wired into Claude Code, Codex, Pi, and OpenCode in one setup command.
Jev Agents & MCP#community#typescript#mcp
CommunityFrancoisChastel/jev-codeTypeScript
agent-chaperone
22GitHub stars
An MCP proxy and hooks adapter that screens an agent's tool calls before they run and the tool results before the agent reads them, with thresholds in a policy file.
