RunSec

RunSec is an AI-powered MCP (Model Context Protocol) server that brings security reasoning directly into developer IDEs, surfacing only high-confidence vulnerabilities paired with ready-to-run proof-of-concept exploits. It integrates with Cursor and VS Code via the MCP protocol, allowing developers and AI agents to detect, verify, and remediate security issues without leaving their editor. The tool is built around a "zero-noise" philosophy: combining static rules with AI reasoning to ensure only issues with a credible execution story reach the developer's backlog.

What It Is

RunSec is a cognitive application security (AppSec) platform delivered as an MCP server. It connects to AI-enabled IDEs and agents to perform real-time security analysis on code, flagging vulnerabilities such as SQL injection (CWE-89) with severity scores, CWE classifications, and concrete curl-based proof-of-concept commands that can be pasted directly into a terminal. The product is positioned as "RunSec Hub — cognitive AppSec for modern teams."

How the Zero-Noise Signal Works

RunSec's core differentiator is its combination of deterministic rules and AI reasoning to filter out false positives. According to the product page, only issues with a "credible execution story" surface to the developer — reducing alert fatigue and accelerating remediation. Each finding includes:

• A severity score (e.g., CRITICAL 9.8)
• A CWE classification and affected code location
• A ready-to-run proof-of-concept the developer can execute immediately to confirm impact

IDE Integration and MCP Workflow

Setup follows a straightforward path: install the RunSec MCP server, open RunSec Hub, navigate to IDE Integration, and add an API key under API Keys. Once connected, the MCP server appears live in the editor. Developers hover a flagged line, request a proof, and receive a concrete exploit command — all without switching context. The live demo on the homepage illustrates this with a Python authentication function containing a SQL injection vulnerability.

Compliance Coverage

RunSec maps its findings to major compliance frameworks, generating automated evidence trails suitable for security reviews and due diligence. The platform covers:

• OWASP ASVS Level 3 Controls — continuous IDE verification mapped to deterministic security checks
• PCI-DSS v4.0 Requirement 6.5 — automated prevention of injection flaws for payment environments
• SOC 2 Trust Services Criteria — evidence trails for logical access and secure change management readiness
• HIPAA Security Safeguards — technical safeguard coverage for regulated workloads

The site notes that RunSec provides automated evidence trails but is not an accredited certifying body; final compliance certification requires a formal audit by authorized organizations.

CI/CD Quality Gate

Beyond IDE use, RunSec emits a strict verdict header from its CI/CD Quality Gate, enabling pipelines to automatically block risky merges. This positions the tool across both the inner loop (IDE) and outer loop (CI/CD) of the software development lifecycle, making it applicable to teams that want security enforcement at multiple stages without manual review overhead.
