  1. OWASP/MCP-Security-Testing-Guide

    OWASP MCP Security Testing Guide is a living, GPL-3.0 collection treating the Model Context Protocol as a security boundary from user through model, MCP client, MCP server and tool to the target system. It covers threats, secure development, host/client controls, supply chain, enterprise gateways, detection, incident response, taxonomy, public incidents, case studies and review checklists, with 79 tests in Chapter 3 (sections 3.1–3.19). It includes a finding template, and it links the MCP Goat lab for safe practice. It is useful to AppSec, red team and SOC people assessing MCP deployments.

  2. https://github.com/dmdhrumilmistry/security-harness

    security-harness is an open-source Claude Code plugin (also packaged for Gemini CLI, Codex and opencode) that orchestrates subagents — sh-recon, sh-hunter, sh-chainer, sh-verifier, sh-reporter — through a static-analysis pipeline covering 15 vulnerability classes (IDOR/BOLA, SQLi, XSS, SSRF, injection, auth, deserialization, path traversal, secrets, CSRF, XXE, open redirect, crypto, race conditions, file upload), producing README/JSON/SARIF/HTML/PDF reports with PoCs, CVSS and CWE/OWASP mappings. It also ships sh-pr-review, a per-PR merge-gate skill that posts inline findings and a commit status scoped only to code the PR itself introduced or aggravated, with caching, dedup via fingerprints, and a scheduled GitHub Action that keeps its per-class knowledge bases fresh by having one AI agent draft updates from allowlisted sources (OWASP, PortSwigger Research, CWE/CAPEC, HackerOne) while a separate adversarial reviewer agent fails-closed against prompt injection before auto-merge.

  4. Agent Control Standard (ACS)

    Agent Control Standard (ACS) is an OWASP GenAI Security Project specification that lets a separate Guardian Agent inspect an AI agent's proposed actions before they execute and return allow/deny/modify/ask/defer over an authenticated JSON-RPC wire, with OpenTelemetry/OCSF audit trails and a CycloneDX/SPDX/SWID AgBOM inventory. The reference implementation runs Microsoft's Agent Governance Toolkit (AGT) behind the ACS contract with Bun, including host shims for Claude Code and OpenCode, and demonstrably denies a destructive `rm -rf /` command from a live coding-agent session while allowing benign ones. The project is explicit about current gaps — the wire is unauthenticated (issue #70) and the reference Guardian fails open by default (issues #32/#37) — and only 2 of 16 lifecycle hooks are evaluated live in v0.1.0.

  5. Agent Threat Rules (ATR) — open detection-rule standard for AI agent threats

    Agent Threat Rules (ATR) is an open, versioned YAML rule format (ATR-YYYY-NNNNN scheme) for detecting AI-agent runtime threats — prompt injection, tool-poisoning, malicious SKILL.md content, and MCP exchange abuse — evaluated by a reference TypeScript engine (with a Python wrapper) shipped as an npm/pip package, CLI, GitHub Action, and Docker scanner with SARIF output. The project positions itself as "Sigma for agent threats," maps rules to OWASP Agentic/LLM Top 10, MITRE ATLAS, and NIST AI RMF, and publishes an extensive (and unusually self-critical) benchmark suite against corpora like garak, PromptBench, and PromptInject, including documented harness bugs and withdrawn recall figures.

  11. agent-egress-bench

    Agent Egress Bench is an open, tool-neutral benchmark maintained by PipeLab (makers of Pipelock) that tests whether products mediating an AI agent's outbound traffic — proxies, egress firewalls, MCP wrappers, agent gateways — actually catch exfiltration attempts caused by prompt injection or misalignment, rather than testing the underlying model itself (that's left to AgentDojo, InjecAgent, CyberSecEval, AgentHarm, ASB). It ships a reproducible Go runner with a proxy/WebSocket/MCP/A2A adapter contract, an offline validator, DSSE-signed evidence bundles, and a CI-runnable GitHub Action, and separates containment from false-positive rate as two distinct scored axes with immutable case IDs and OWASP Agentic Top 10/MITRE ATT&CK mappings. Its governance explicitly permits third parties to publish results unfavorable to the maintainer's own Pipelock product.

    DarkMoon is a self-hosted, GPLv3 AI penetration testing platform that orchestrates 50 specialist agents over an MCP-gated toolbox (Nuclei, BloodHound, sqlmap, Impacket, Naabu, httpx, ffuf, etc.) to autonomously run recon-to-exploitation across web, API, Active Directory, Kubernetes, multi-cloud, CI/CD, databases, IoT firmware, and AI/LLM inference endpoints. It uses a Privacy Gateway that tokenizes real IPs/hosts/credentials into placeholders so raw infrastructure data never reaches the (optionally local, e.g. Ollama/llama.cpp) LLM, and can generate sandbox-validated, exploit-retested pull requests for findings. It also ships a dedicated LLM agent that probes OpenAI-compatible/Ollama/vLLM/TGI inference endpoints for the OWASP LLM Top 10 (prompt injection, jailbreaks, system-prompt leakage) using garak-backed probes.

It also includes an LLM/AI surface reconnaissance module that passively fingerprints LLM-powered apps and runs authorization-gated OWASP LLM Top 10 probes. All external API keys are optional, with graceful degradation when unset.​

  41. AI Repository Security Baseline

    A collection of drop-in instruction/config files (AGENTS.md, CLAUDE.md, .cursor/rules, .aiignore, etc.) that give AI coding agents a shared security and privacy playbook: never read .env or secrets files, no hardcoded credentials, OWASP hygiene, PII protection, GDPR support, restricted filesystem/network access, no destructive commands without confirmation, mandatory tests, and dependency/CI change controls including typosquatting checks before adding packages. Each tool-specific file (Cursor, Copilot, Windsurf, Cline, Aider, Amazon Q, Junie, Devin, Cody) delegates to one canonical AGENTS.md so teams maintain a single source of truth across all agents in use.

  42. DeepTeam

    DeepTeam is an open-source, locally-runnable red teaming framework for LLM applications, agents, and RAG pipelines, built on the DeepEval evaluation library. It simulates jailbreaking, prompt injection, and multi-turn adversarial attacks against 50+ vulnerability categories such as PII leakage, BOLA, BFLA, SQL injection, SSRF, and agentic goal theft, maps results to OWASP, NIST, MITRE, BeaverTails, and Aegis frameworks, and ships production guardrails to block the same issues at runtime.

  43. anmolksachan/AI-ML-Free-Resources-for-Security-and-Prompt-Injection

    A GitHub-hosted, structured learning roadmap for AI/ML security and prompt injection, covering prerequisites (web/API basics), LLM fundamentals (OWASP LLM Top 10 2025, MITRE ATLAS), attack classes (prompt injection, indirect prompt injection, jailbreaking, multi-turn attacks, MCP tool poisoning, RAG poisoning, model extraction, supply chain), and hands-on labs/tools (Garak, PyRIT, ART, CleverHans, ModelScan). It also catalogs named CVEs in AI coding assistants (CVE-2025-53773 GitHub Copilot RCE, CVE-2025-54135 Cursor IPI-to-RCE) and points to bug bounty platforms, checklists for pentesting LLM apps, and community resources (AI Village, Embrace the Red, r/llmsecurity).

  44. Microsoft Agent Governance Toolkit

    Agent Governance Toolkit (AGT) is a Microsoft open-source framework that intercepts every tool call, message, and delegation made by an AI agent in deterministic application-layer code before it reaches the model, enforcing YAML/OPA/Cedar policies, agent identity (SPIFFE/DID/mTLS), and tamper-evident audit logs. It ships SDKs for Python, TypeScript, .NET, Rust, and Go, a Claude Code plugin, and CLI tools (agt verify, agt red-team scan) for OWASP-style compliance checks and prompt-injection audits. The project explicitly frames prompt-level safety as insufficient, citing a 100% adversarial attack success rate on GPT-4o/Claude 3/Llama-3 (Andriushchenko et al., ICLR 2025) as motivation for application-layer enforcement instead.

  45. 0xSteph/pentest-ai-agents

    pentest-ai-agents is a GitHub repo providing 50+ Claude Code subagent markdown files that turn Claude into a routed offensive-security assistant, covering recon, web, Active Directory, cloud, mobile, wireless, social engineering, payload crafting (msfvenom/Donut), reverse engineering (Ghidra/JadX/Radare2), C2 tuning (Sliver/Mythic/Havoc/Cobalt Strike), container breakout, and LLM red-teaming (OWASP LLM Top 10, prompt injection, RAG poisoning, MCP abuse). It distinguishes Tier 1 advisory agents from Tier 2 execution-capable agents that enforce a declared-scope guard before running commands, and ships a SQLite findings database, hardened CI validator, and an offline Docker bundle.

  46. requie/LLMSecurityGuide

    A GitHub reference guide covering the OWASP Top 10 for LLM Applications 2025 and the OWASP Top 10 for Agentic Applications 2026 (ASI01–ASI10, released December 2025 at Black Hat Europe), with Python code samples for attacks (prompt injection, training-data extraction, RAG poisoning, agent goal hijacking, memory poisoning) and matching defenses (guardrails, memory integrity validation, tool-usage guards, zero-trust agent execution). It also curates red-teaming and guardrail tooling — garak, DeepTeam, Promptfoo, ARTKIT, Meta LlamaFirewall, LLM Guard, NeMo Guardrails, Amazon Bedrock Guardrails, Langfuse — plus an MCP security checklist and a security readiness checklist for LLM/agentic deployments.
