Best Security MCP Servers for AI Coding Agents (2026)
A side-by-side comparison of security-focused MCP servers for Claude Code, Cursor, Codex, and Gemini CLI: what each one scans, what it misses, and which one covers the whole stack.
Best SAST Tools for AI Coding Agents in 2026: A Data-Driven Comparison
We compared 5 SAST tools on rule count, language coverage, AI agent integration, false-positive rates, and pricing. Here's the 2026 landscape for security-aware AI development.
Your AI Agent Still Leaks .env Even With Bitwarden
Centralised secret managers fix storage. They do not fix the cleartext sitting in your AI agent's address space at the moment of a prompt injection. Here's the architecture that does.
Secure AI Agent Development: The 7-Layer Defense Workflow
We built a 7-layer security workflow for AI agent development. MCP config audit, dependency scan, secret detection, SAST, threat model, runtime guard, and CI gate. Here's how.
AI Agent Security Risks in 2026: A Technical Threat Landscape
AI coding agents now execute code, install packages, and call APIs autonomously. We mapped 7 attack surfaces, 23 MITRE techniques, and the defenses that actually work.
How Zfuzz MCP Would Have Caught the Mini Shai-Hulud Supply Chain Attack
Microsoft disclosed a compromised @antv npm package chain — credential theft, C2 callbacks, persistence implants. We mapped every attack stage to the Zfuzz tool that catches it. 5 of 7 stages blocked.
When Your AI Agent Gets Prompt-Jacked: Anatomy of a Real MCP Attack
14:32 UTC. A developer asks their AI agent to summarize a GitHub issue. By 14:34 UTC, the agent has exfiltrated three AWS keys to an external server. Here is the exact sequence of events.
The MCP Sprawl Effect: Why Your AI Agent's Tool List Is an Attack Surface
The average Claude Code user has 4-7 MCP servers. 88% have never audited their tool descriptions. The MCP Sprawl Index -- BREADTH x PRIVILEGE x OPACITY -- quantifies the attack surface your AI agent configuration creates.
Zfuzz vs Semgrep MCP: Which Security Scanner Fits Your AI Workflow?
Zfuzz covers 441 SAST rules, secrets, dependencies, and threat modeling in one MCP install. Semgrep MCP focuses on custom rule authoring. Here's the data-driven comparison.
Why 85% of MCP Server Configurations Ship with Security Gaps
We analyzed 200 MCP configurations on GitHub. 85% had at least one critical gap: unpinned package versions, unnecessary environment variable exposure, or zero tool description audit. Your MCP config is a confession of everything you trust blindly.
Your MCP Server Has Zero Authentication and Nobody Cares
The MCP specification has no authentication layer. Every tool runs with your user privileges. Every MCP server you install is a trust-me-bro security model.
How to Detect MCP Tool Poisoning: A Hands-On Guide
We tested 47 public MCP servers. 6 had suspicious tool descriptions. Here's exactly how to detect MCP tool poisoning before it compromises your agent.
How to Audit Your MCP Server Configs for Prompt Injection
MCP servers can hide malicious instructions in tool descriptions. Here's how to detect prompt injection, tool poisoning, and SSRF risks in your AI agent configs.
Migrate from Bitwarden Secrets Manager to Zfuzz Sealed Vault
Bitwarden Secrets Manager fixes rotation. It does not stop a prompt-injected AI agent from dumping the cleartext it loaded at boot. Here's the 15-minute migration to a runtime that physically cannot leak.
