Model Context Protocol (MCP) & Extension Security
Model Context Protocol (MCP) is becoming the standard for connecting AI models to local tools, databases, and enterprise services. However, malicious or vulnerable MCP servers can expose host systems to command injection, file system traversal, credential theft, and unauthorized tool calls. AgentClad Security conducts specialized security audits of custom and open-source MCP tools, servers, and integrations.
Technical Scoping Activities
- MCP tool parameter schema validation and sanitization analysis
- Resource access path traversal and local file disclosure audit
- Prompt template injection vector analysis in MCP servers
- Transport security (STDIO vs SSE vs HTTP) and authentication review
- Malicious MCP server capability extraction and sandbox escape testing

Practice Area FAQs
Why is MCP security different from standard REST API security?
MCP tools are invoked directly by non-deterministic LLMs based on natural language context rather than structured code calls, creating unique prompt injection and tool argument poisoning vectors.
Can you audit third-party MCP servers before we install them internally?
Yes, we provide third-party MCP tool vetting reports to ensure extensions do not contain dangerous file access or shell execution capabilities.
