Strix

Strix are autonomous AI penetration testing agents that act just like real hackers - they run your code dynamically, find vulnerabilities, and validate them through actual proofs-of-concept. Built for developers and security teams who need fast, accurate security testing without the overhead of manual pentesting or the false positives of static analysis tools.

Key Capabilities:

• Full pentesting toolkit - reconnaissance, exploitation, and validation out of the box
• Multi-agent orchestration - teams of AI pentesters that collaborate and scale
• Real exploit validation - working PoCs, not false positives like legacy vulnerability scanners
• Developer‑first CLI - actionable findings with remediation guidance
• Auto‑fix & reporting - generate patches and compliance-ready pentest reports

• Application Security Testing - Detect and validate critical vulnerabilities in your applications
• Rapid Penetration Testing - Get penetration tests done in hours, not weeks, with compliance reports
• Bug Bounty Automation - Automate bug bounty research and generate PoCs for faster reporting
• CI/CD Integration - Run tests in CI/CD to block vulnerabilities before reaching production

Prerequisites:

• Docker (running)
• An LLM API key from any supported provider (OpenAI, Anthropic, Google, etc.)

# Install Strix
curl -sSL https://strix.ai/install | bash

# Configure your AI provider
export STRIX_LLM="openrouter/z-ai/glm-5.3"
export LLM_API_KEY="your-api-key"

# Run your first security assessment
strix --target ./app-directory

• Open Source - free, runs locally with Docker and your own LLM key. Quick Start
• Strix Cloud - no setup, validated findings, one-click autofix, and PR reviews. Run a pentest →

Strix is agent-ready. Give Claude Code, Cursor, Codex, or any SKILL.md-compatible agent the ability to run pentests, fix findings, and set up CI scanning:

npx skills add usestrix/strix

This installs nine skills for running pentests, fixing findings, and CI scanning, against code, web apps, APIs, and the OWASP Top 10. Agents can use the local CLI or the managed cloud with the same engine.

See AGENTS.md for the quick reference, docs.strix.ai/llms.txt for the CLI, and docs.app.strix.ai for the API.

Strix agents come equipped with a comprehensive offensive security toolkit - the same tools used by professional penetration testers and ethical hackers:

• HTTP Interception Proxy - Full request/response manipulation and analysis with Caido
• Browser Exploitation - Automated browser for testing XSS, CSRF, clickjacking, and auth bypass flows
• Shell & Command Execution - Interactive terminal for exploit development and post-exploitation
• Custom Exploit Runtime - Python sandbox for writing and validating proof-of-concept exploits
• Reconnaissance & OSINT - Automated attack surface mapping, subdomain enumeration, and fingerprinting
• Static & Dynamic Code Analysis - SAST + DAST capabilities for comprehensive application security testing
• Vulnerability Knowledge Base - Structured findings with CVSS scoring and OWASP classification

Strix identifies, validates, and exploits a wide range of security vulnerabilities across the OWASP Top 10 and beyond:

• Broken Access Control - IDOR, privilege escalation, auth bypass
• Injection Attacks - SQL injection, NoSQL injection, OS command injection, SSTI
• Server-Side Vulnerabilities - SSRF, XXE, insecure deserialization, RCE
• Client-Side Attacks - XSS (stored/reflected/DOM), prototype pollution, CSRF
• Business Logic Flaws - Race conditions, payment manipulation, workflow bypass
• Authentication & Session - JWT attacks, session fixation, credential stuffing vectors
• Infrastructure & Cloud - Misconfigurations, exposed services, cloud security issues
• API Security - Broken authentication, mass assignment, rate limiting bypass

Advanced multi-agent orchestration for comprehensive automated penetration testing:

• Distributed Pentesting - Specialized AI agents for recon, exploitation, and post-exploitation
• Scalable Security Testing - Parallel execution across multiple targets for fast, comprehensive coverage
• Dynamic Coordination - Agents share discoveries, chain vulnerabilities, and collaborate like a red team

Every scan writes its results to disk as it runs. Bring them up in a local dashboard with a single command:

# Open the most recent run
strix view

# ...or open a specific run by name
strix view my-run-name

# Expose the viewer on all IPv4 interfaces at a fixed port
strix view --host 0.0.0.0 --port 8080 --no-open

The dashboard shows the findings, a live map of the agent team, and past runs. Nothing leaves your machine, and the UI ships prebuilt. strix view binds to 127.0.0.1 and prints a tokened link that grants access to the run, so share it carefully.

See the viewer documentation for the options and for reaching the viewer from another machine.

# Scan a local codebase
strix --target ./app-directory

# Security review of a GitHub repository
strix --target https://github.com/org/repo

# Black-box web application assessment
strix --target https://your-app.com

Point Strix at an API contract and it tests every declared endpoint instead of having to discover them by crawling. Pair the spec with the live base URL so the agent knows where to send traffic:

# OpenAPI / Swagger file, Postman export, or a live collection by id
strix --target ./openapi.yaml --target https://api.your-app.com
strix --target postman://<collection-uuid> --target https://api.your-app.com

# Grey-box authenticated testing
strix --target https://your-app.com --instruction "Perform authenticated testing using credentials: user:pass"

# Multi-target testing (source code + deployed app)
strix -t https://github.com/org/app -t https://your-app.com

# Targets from a file, one target per non-empty, non-comment line
strix --target-list ./targets.txt

See the CLI reference for every option, including scan modes, diff scope, instruction files, and budgets.

Run Strix programmatically without interactive UI using the -n/--non-interactive flag - perfect for servers and automated jobs. The CLI prints real-time vulnerability findings and the final report before exiting. Exits with non-zero code when vulnerabilities are found.

strix -n --target https://your-app.com

Strix can be added to your pipeline to run a security test on pull requests with a lightweight GitHub Actions workflow:

name: strix-penetration-test

on:
  pull_request:

jobs:
  security-scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v6
        with:
          fetch-depth: 0

      - name: Install Strix
        run: curl -sSL https://strix.ai/install | bash

      - name: Run Strix
        env:
          STRIX_LLM: ${{ secrets.STRIX_LLM }}
          LLM_API_KEY: ${{ secrets.LLM_API_KEY }}

        run: strix -n -t ./ --scan-mode quick

export STRIX_LLM="openrouter/z-ai/glm-5.3"
export LLM_API_KEY="your-api-key"

# Optional
export LLM_API_BASE="your-api-base-url"  # if using a local model, e.g. Ollama, LMStudio

Instead of a metered API key, you can run Strix on your ChatGPT Plus/Pro subscription:

strix auth login chatgpt             # sign in with your ChatGPT account
export STRIX_LLM="chatgpt/gpt-5.4"   # chatgpt/<model> runs on the subscription
strix auth status                    # show the active sign-in, or logout to forget it

Run scans on app.strix.ai from the terminal, without Docker or an LLM key:

strix cloud login                                  # browser sign-in, one credential per install
strix cloud scans start --source . --yes --wait    # scan local code, approving the upload
strix cloud scans start --engagement-type live_test --domain-ids <uuid> --wait
strix cloud vulns list --severity critical

Every REST API operation has a matching strix cloud <resource> <verb> command. Run strix cloud to list the resources, and add help to a resource to list its verbs. Output is JSON when stdout is not a terminal or when you pass --json. Binary downloads are the exception: redirect the raw bytes, or combine --output FILE --json for download metadata.

See the cloud CLI documentation for scopes, workspaces, billing, and source-upload options.

Strix can connect to Model Context Protocol (MCP) servers you list and expose their tools to the agent during a run. Create ~/.strix/mcp-servers.json with a JSON list of local stdio servers or remote http servers:

[
  {
    "name": "github",
    "transport": "http",
    "url": "https://api.githubcopilot.com/mcp/",
    "auth": { "kind": "bearer", "token": "your-token" },
    "allowed_tools": ["list_issues"]
  }
]

Each server's tools are namespaced by name, for example github_list_issues. See the MCP documentation for the full schema, tool filtering, and stdio servers.

Recommended models for best results:

• Z.ai GLM-5.3 on OpenRouter - openrouter/z-ai/glm-5.3 (the default pick)
• OpenAI GPT-5.4 - openai/gpt-5.4
• Anthropic Claude Sonnet 4.6 - anthropic/claude-sonnet-4-6
• Google Gemini 3 Pro Preview - vertex_ai/gemini-3-pro-preview
• DeepSeek V4 Pro - deepseek/deepseek-v4-pro
