SkillRisk is a specialized security analysis tool designed for the AI Agent ecosystem, specifically focusing on Claude Code and Model Context Protocol (MCP) skills. As developers give AI agents more permissions (shell access, file manipulation), the risk of executing malicious code increases. SkillRisk acts as a static analysis firewall, auditing skill definitions before you install or run them. Key Features: Hook Hijacking Detection: Identifies malicious PreToolUse hooks that attempt to execute silent background commands or install malware. Permission Auditing: Flags skills requesting excessive privileges (e.g., unnecessary root/sudo access or write permissions to sensitive directories). Data Leak Prevention: Scans for hardcoded API keys, credentials, and potential data exfiltration patterns. MCP Server Integrity: Vets external MCP server configurations for known malicious endpoints. Privacy & Security: SkillRisk operates on a "Local-First" philosophy. It performs in-memory static analysis, meaning your uploaded code is processed in temporary RAM and immediately purged after the report is generated. It does not store user code. Pricing: Offers a Free Tier for basic scanning needs and a Premium plan for advanced hook redirection audits and priority support.

    As an online platform, a stable internet connection is required to use CodeSandbox effectively, which could be a limitation in areas with poor connectivity.
  • Free Tier Limitations
    The free version comes with certain restrictions on resources and functionality, which might not be sufficient for larger or more complex projects.
  • Security Concerns
    Storing code in an online platform can raise security concerns, especially for sensitive or proprietary projects.
  • Learning Curve
    Despite its ease of use, developers new to online IDEs might face a learning curve in adapting from traditional, local development environments.

Questions & Answers

As answered by people managing CodeSandbox and SkillRisk.org.

What makes your product unique?

SkillRisk.org's answer:

SkillRisk is the first dedicated security scanner built specifically for the Claude Code and Model Context Protocol (MCP) ecosystem. Unlike general-purpose code linters, SkillRisk understands agent-specific attack vectorsโ€”such as PreToolUse hook hijacking, implicit permission leaks in JSON/YAML definitions, and data exfiltration patterns in MCP server configurations. It brings "Static Application Security Testing" (SAST) to the world of AI Agents.

Why should a person choose your product over its competitors?

SkillRisk.org's answer:

Most traditional security tools audit application code but ignore the configuration layer of AI agents. You should choose SkillRisk because: Context-Aware: It detects risks specific to AI agents (e.g., giving an LLM rm -rf permissions) that standard linters miss. Pre-Runtime Safety: It allows you to audit third-party skills before you install them, preventing supply chain attacks. Privacy-First: Our "Local-First" architecture ensures your skill definitions are analyzed in-memory and never stored on our servers.

How would you describe the primary audience of your product?

SkillRisk.org's answer:

Our primary audience includes AI Engineers, DevOps professionals, and software developers who are building autonomous agents using Claude Code or implementing MCP servers. It is a must-have tool for anyone integrating community-contributed skills or third-party tools into their agent's workflow.

What's the story behind your product?

SkillRisk.org's answer:

We built SkillRisk after realizing a terrifying gap in the AI workflow: developers scrutinize human code in Pull Requests but blindly copy-paste "Skills" that give AI agents shell access. After witnessing an incident where a malicious "Color Picker" skill silently exfiltrated credentials and caused $54,000 in cloud bills, we decided to build a "firewall" for AI skills. We treat Agent Skills as executable code that requires strict auditing.

Which are the primary technologies used for building your product?

SkillRisk.org's answer:

The platform utilizes a custom-built Static Analysis Engine specifically tuned for parsing JSON, YAML, and Markdown skill definitions. It employs strictly typed rule sets to detect logic vulnerabilities and permission scopes without executing the code. The web interface is designed for zero-persistence data processing to ensure maximum security.

Who are some of the biggest customers of your product?

SkillRisk.org's answer:

AI Engineers within the Anthropic developer community DevOps teams using Vercel Infrastructure developers at Nvidia Open source maintainers of MCP servers

  • Thankful for CodeSandbox
    I am thankful for a platform like CodeSandbox because it allows me to offload majority of the processing power and memory resources to the cloud. With a local VS Code installed, I can tunnel in via a remote connection to work on my projects, tinker, or do a deep-dive on certain topics; all while ensuring that the RPi 4 still has sufficient resources left to run other things in the background. - Source: dev.to / over 1 year ago
