Prompt-injection detection with decision models

Example of using Jev as a webhook guardrail inside the agentgateway proxy to inspect model requests and responses.

Large catalog of Claude Code agents, commands, hooks and MCPs, listed with community Jev mods for guardrails and subagent models.

Python multi-agent runtime with native Jev support: agents ask typed questions via a decision client separate from the text model.

x402 pre-payment risk-check provider combining sanctions lists, phishing feeds and simulation with Jev checks for injected instructions.

Cisco's security scanner for agent skills, with a System One analyzer as an advisory tier that cannot emit findings or change severity.

MCP proxy and hooks that screen agent tool calls before they run and their results before the agent reads them, using Jev judgments.

Xano backend template where Jev judges each agent tool call as safe, needs review or dangerous, and uncertain calls wait for a human.

Effect-based safety gate for coding-agent shell commands: fast rules first, then Jev decides allow/deny plus eleven risk checks.

DeepSeek Harness plugin where Jev classifies risk, irreversibility, task fit and injection for every tool call before it runs.

DeepSeek Harness plugin where Jev prunes long tool output, screens fetched pages for injected instructions and gates completion claims.

Invalidation layer for agent memory: each fact gets a lease and Jev yes/no votes decide whether new evidence ends it.

Open-source agent guardrails that use Jev or LAYA to check prompts, retrieved content, tool calls and outputs for injection and risk.

Starter kit that gates every MCP tool call with Kinde identity checks plus Jev risk signals, then allows, holds for approval or stops it.

Portuguese-language agent skill for millisecond Jev decisions via OpenRouter, with validation, an MCP mode and calibration evals.

Agent-ergonomic Jev CLI and PreToolUse hook that scores shell commands for hazards and screens fetched text for injection.

jevctl: Node CLI for typed Jev judgments (verify claims, screen agent hijacks, classify) with exit codes for CI gating.

Local-first app that files documents into category folders using Jev decisions on category, confidentiality, subject and injection risk.

Gateway admission control that asks Jev what each incoming request is trying to do, filtering prompt injection and abuse.

Coding-agent tools on Jev with public benchmarks: a strict command gate, a code-review router Action, and use cases.

PreToolUse firewall for Claude Code and Codex: shell-aware rules first, then Jev returns allow, ask or block, failing closed.

Security hook giving Codex, Copilot, Gemini, Cursor, pi, OpenCode and ACP an auto-mode-like guard via three Jev questions.

OpenBles Firewall 1: open prompt-injection detector for agent inputs, with a Claude Code hook and an optional Jev backend.

Claude Code mod that hands small decisions (routing, skill choice, screening, gating, trimming) to Jev or another decision backend.

Drop-in proxy for Playwright MCP that adds Jev page triage, prompt-injection masking, snapshot pruning and risky-action gating.

MCP server that scores every search query, result and fetched page an agent sees for relevance, credibility and steering risk.

Reviews agent skills, MCP configs and source with local static checks plus Jev before install, reporting evidence, risk and coverage gaps.

Semantic MCP firewall that screens tool calls, results and descriptions with Jev, plus allowlists and session taint tracking.

Four Java tools on one kernel that ask Jev whether something was delivered as required, with deterministic gates keeping the final say.

Hosted guardrails API checking LLM inputs, outputs and retrieved documents for injection, jailbreaks and leaks in one Jev call.

Test harness for any Jev-API decision model: accuracy, calibration and robustness probes for reordering, injection and padding.
