SAST MCP Server

Static Application Security Testing (SAST) for AI agents. A production-ready MCP server that gives any AI agent the ability to scan code for security vulnerabilities.

Supports 11 industry-standard scanners:

Works with any MCP-compatible agent: Gemini CLI, Claude Desktop, OpenAI Agents, Cursor, Windsurf, and more.

Features

• 🔍 11 SAST/SCA/DAST scanners with a unified output format
• 🌳 AST-aware context — shows the full enclosing function, not just a line number
• 📊 Severity & confidence filtering — focus on what matters
• 🔀 Git diff mode — scan only modified files for incremental reviews
• 🙈 Ignore management — suppress false positives with audit trail
• 📄 Pagination — handle large codebases without overwhelming the agent
• 🌐 Dual transport — stdio (local) or Streamable HTTP (remote deployments)
• 🔐 JWT & API key authentication — secure remote deployments
• 📦 One command install — pip install sast-mcp-server
• 🚀 Multi-scanner mode — run all installed scanners in parallel with deduplication
• 📋 SARIF export — CI/CD integration with GitHub, GitLab, Azure DevOps
• 🏗️ IaC scanning — Terraform, Kubernetes, Docker security policies
• 🔑 Secret detection — find hardcoded API keys, tokens, and passwords in code and git history
• 📦 SCA / dependency CVEs — scan lock files for known vulnerabilities against the OSV database
• 🕷️ DAST — dynamic baseline scans of running apps via OWASP ZAP + Docker
• 📈 Baselines & trend tracking — cache scans and diff against a saved baseline
• 🤖 MCP Prompts & Resources — pre-built security workflows and live dashboards for agents
• 📤 Dashboard integrations — push SARIF results to DefectDojo or GitHub Code Scanning
• 🩹 AI-assisted remediation — generate fix prompts and apply agent-written patches via git apply

Quick Start

The server is only as useful as the scanners installed alongside it. Pick the install path that matches how much of the toolset you want out of the box.

Option 1 — Full container (recommended: 9 scanners, zero setup)

docker pull ghcr.io/skyrxin/sast-mcp-server:full

Bundles bandit, njsscan, bearer, semgrep, trivy, checkov, gitleaks, osv-scanner, and grype so scan_all works immediately. Or bring up an HTTP server with one command:

docker compose up          # serves http://localhost:8080/mcp + /health /ready /metrics

Option 2 — pip extra (4 pip-installable scanners)

pip install "sast-mcp-server[scanners]"   # adds bandit, njsscan, semgrep, checkov

Option 3 — minimal / custom

pip install sast-mcp-server               # server only — bring your own scanners
uvx sast-mcp-server                        # run without installing

Then install whichever scanners you need (binary scanners aren't pip packages):

pip install bandit njsscan semgrep checkov     # pip-installable
# trivy:        https://aquasecurity.github.io/trivy/latest/getting-started/installation/
# grype:        https://github.com/anchore/grype#installation
# gitleaks:     https://github.com/gitleaks/gitleaks#installing
# osv-scanner:  https://google.github.io/osv-scanner/installation/
# bearer:       https://docs.bearer.com/installation/
# codeql:       https://github.com/github/codeql-cli-binaries/releases

What ships where

At startup the server logs how many scanners it can actually see (e.g. Scanners available: 9/11 (...)), and the list_scanners tool / /ready endpoint report the same — so it's always obvious what you have.

Usage with AI Agents

Gemini CLI

Install as an extension:

gemini extensions install https://github.com/Skyrxin/sast-mcp-server

Or add to your ~/.gemini/settings.json:

{
  "mcpServers": {
    "sast": {
      "command": "uvx",
      "args": ["sast-mcp-server"]
    }
  }
}

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "sast": {
      "command": "uvx",
      "args": ["sast-mcp-server"]
    }
  }
}

See full Claude Desktop guide.

Cursor IDE

Add to Cursor Settings → MCP Servers:

{
  "mcpServers": {
    "sast": {
      "command": "uvx",
      "args": ["sast-mcp-server"]
    }
  }
}

See full Cursor guide.

OpenAI Agents SDK

from agents.mcp import MCPServerStdio

sast_server = MCPServerStdio(command="uvx", args=["sast-mcp-server"])

See full OpenAI guide.
