MCP server security for AI coding agents
A critical RCE in Anthropic's own MCP Inspector (CVSS 9.4) and two Cursor CVEs show that giving AI agents tool access creates a new, largely unvetted attack surface.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.

OWASP has ranked prompt injection the #1 LLM risk for two straight editions, yet almost no one scores agent skill packages for it consistently. Here's a rubric.
Research found ~40% of Copilot suggestions were vulnerable, and devs using AI assistants trusted their code more. MCP lets you scan before merge.
29M new hardcoded secrets hit public GitHub in 2025, up 34% YoY — and 3% of MCP servers in production carry hardcoded credentials as theft traps.
Five CVEs in 2025 alone trace MCP tool compromise back to one root cause: unsanitized strings piped into exec(). Here's how to expose and consume MCP safely.
Shai-Hulud infected 500+ npm packages via stolen tokens in 2025. Agent skill registries are repeating the same unsigned-artifact mistake — here's the fix.
STRIDE has six categories from 1999. OWASP's LLM Top 10 and MITRE ATLAS's ~84 techniques show why agentic AI needs new threat-modeling columns, not a new framework.
The OWASP LLM Top 10 is the closest thing the field has to a shared checklist for AI security. Here is what each of the ten risks actually means, in plain language, with the defenses that matter.
The biggest MCP protocol news of 2026 is a major specification overhaul that fixes old flaws and shifts a load of new security responsibility onto developers.
