agent-security-scanner-mcp

Security scanner for AI coding agents, MCP servers, prompts, and AI-suggested packages.

Run it before Claude Code, Cursor, Windsurf, Cline, OpenCode, or another agent trusts new code, tools, prompts, or dependencies.

Copy-Paste Start

Scan any repo and get an A-F agent security grade:

npx agent-security-scanner-mcp scan-project . --verbosity compact

Install the scanner into your AI coding client:

npx agent-security-scanner-mcp init claude-code

Replace claude-code with cursor, claude-desktop, windsurf, cline, kilo-code, opencode, or cody.

Audit an MCP server before adding it to an agent:

npx agent-security-scanner-mcp scan-mcp ./path/to/mcp-server --verbosity compact

Check AI-generated imports for package hallucinations:

npx agent-security-scanner-mcp scan-packages ./src/app.ts npm --verbosity compact

What It Catches

Risk	Why agents need it	Command
Vulnerable generated code	Agents can introduce SQL injection, XSS, command injection, unsafe crypto, and secrets	`scan-project`, `scan-security`, `scan-diff`
MCP server attacks	MCP tools can poison descriptions, spoof names, exfiltrate env vars, or execute commands	`scan-mcp`
Prompt injection	Agents often process untrusted docs, tickets, pages, and tool output	`scan-prompt`
Unsafe agent actions	Catch dangerous shell/file/network actions before execution	`scan-action`
Hallucinated packages	AI often invents dependency names that attackers can later squat	`check-package`, `scan-packages`
SBOM and CVEs	Generate CycloneDX SBOMs and scan dependencies with OSV.dev	`sbom-generate`, `sbom-vulnerabilities`
Semantic review	LLM-powered review that uses project intent to find context-aware issues	`cr-agent`

Demos

Run a safe local demo that creates intentionally vulnerable fixtures, scans them, and cleans them up.

# MCP audit demo: tool poisoning, spoofed tool name, command execution, secret exposure

npx agent-security-scanner-mcp demo --type mcp --no-prompt

Package hallucination demo: real imports mixed with fake AI-generated package names

npx agent-security-scanner-mcp demo --type packages --no-prompt

Expected demo shape:

"grade": "F", "findings_count": 8, "findings": [ { "rule": "mcp.description-injection", "severity": "ERROR", "message": "Tool description contains imperative language directed at the LLM." }, { "rule": "mcp.tool-name-spoofing", "severity": "ERROR", "message": "Tool name is close to a well-known MCP tool name." } ] }

Install In Your Agent

npx agent-security-scanner-mcp init claude-code

Client	Setup
Claude Code	`npx agent-security-scanner-mcp init claude-code`
Cursor	`npx agent-security-scanner-mcp init cursor`
Claude Desktop	`npx agent-security-scanner-mcp init claude-desktop`
Windsurf	`npx agent-security-scanner-mcp init windsurf`
Cline	`npx agent-security-scanner-mcp init cline`
Kilo Code	`npx agent-security-scanner-mcp init kilo-code`
OpenCode	`npx agent-security-scanner-mcp init opencode`
Cody	`npx agent-security-scanner-mcp init cody`
Interactive picker	`npx agent-security-scanner-mcp init`

Then restart the client. Your agent can call the scanner as an MCP tool.

Agent Playbook

Paste this into an agent task when you want it to work safely:

Before trusting new code, dependencies, prompts, or MCP tools, run:

npx agent-security-scanner-mcp scan-project . --verbosity compact
npx agent-security-scanner-mcp scan-packages ./src/app.ts npm --verbosity compact when imports change
npx agent-security-scanner-mcp scan-mcp ./path/to/mcp-server --verbosity compact before adding MCP servers
npx agent-security-scanner-mcp scan-diff --base main --target HEAD before opening a PR

Fix high-confidence security findings before continuing.

Common Workflows

Before You Trust An Agent-Written PR

npx agent-security-scanner-mcp scan-diff --base main --target HEAD --verbosity compact

npx agent-security-scanner-mcp scan-packages ./src/app.ts npm --verbosity compact

Before Installing An MCP Server

npx agent-security-scanner-mcp scan-mcp ./path/to/mcp-server --verbosity compact

Before Adding A Dependency Suggested By AI

npx agent-security-scanner-mcp check-package express npm

npx agent-security-scanner-mcp scan-packages ./package.json npm --verbosity compact

Add CI

npx agent-security-scanner-mcp init-ci github

Generate Share Copy From A Real Scan

npx agent-security-scanner-mcp scan-project . --verbosity compact > scan-result.json

npx agent-security-scanner-mcp share-kit --scan-result scan-result.json --output share-kit.md

CLI Reference

Command	Use
`scan-project`	Full project scan with A-F grade
`scan-security`	Single-file security scan
`scan-diff --base main --target HEAD`	Scan changed files only
`scan-mcp`	Audit an MCP server before install
`scan-prompt " "`	Detect prompt injection and jailbreak attempts
`scan-action`	Pre-execution safety check for shell/file/network actions
`check-package`	Verify one package exists
`scan-packages`	Verify imports/dependencies in a file
`doctor`	Check local setup health
`quickstart --client cursor`	Generate repo-specific next steps
`share-kit`	Generate public-safe launch/share copy
`export-vanta`	Export scan evidence to the ProofLayer Vanta integration

All scanner outputs support context-friendly verbosity:

--verbosity minimal   # counts only, best for CI

--verbosity compact # default, best for agents and humans --verbosity full # audit/debug detail

MCP Tools For Agents

When installed as an MCP server, agents get these tool families:

Tool family	Purpose
`scan_security`, `fix_security`, `scan_git_diff`, `scan_project`	Code and repo security
`scan_mcp_server`, `scan_skill`	MCP and AI skill security
`scan_agent_prompt`, `scan_agent_action`	Prompt/action safety
`check_package`, `scan_packages`	Package hallucination detection
`sbom_generate`, `sbom_scan_vulnerabilities`, `sbom_diff`, `sbom_export_report`	Supply-chain and release evidence
`get_compliance_controls`, `evaluate_compliance`	SOC2/GDPR/AIUC-1 technical evidence
`scanner_health`	Runtime diagnostics

Why Developers Install It

One npx command gives an A-F security grade for AI-written code.
MCP-specific checks catch risks that normal SAST tools miss.
Package hallucination detection checks 4.3M+ package names across npm, PyPI, RubyGems, crates.io, pub.dev, CPAN, and raku.land.
Output is compact by default so coding agents can read it without burning the context window.
Works as a CLI, MCP server, GitHub Action workflow, Apify Actor, and semantic review agent.

Semantic Code Review

cr-agent is bundled with the npm package for LLM-powered semantic review. It reads project intent, then looks for code that violates that intent.

npx cr-agent analyze ./path/to/project -p claude-cli --verbose

npx cr-agent analyze ./path/to/project -p openai --format sarif

Use it when rule-based scanning is not enough and the question is, "Does this code make sense for what this project is supposed to do?"

SBOM And Compliance Evidence

npx agent-security-scanner-mcp sbom-generate .

npx agent-security-scanner-mcp sbom-vulnerabilities . npx agent-security-scanner-mcp sbom-check-hallucinations . npx agent-security-scanner-mcp evaluate-compliance . --framework soc2-technical

Useful before releases, SOC 2 evidence collection, vendor reviews, and AI-generated dependency changes.

Apify Actor

Run the scanner as an Apify Actor when you want a hosted API or scheduled scans:

"actorId": "folkloric_morale/agent-security-scanner", "input": { "target": "repository", "repoUrl": "https://github.com/your-org/your-agent.git", "repositoryScanMode": "quick", "includeTestFiles": false, "maxRepositoryFiles": 150, "severityThreshold": "medium" } }

Latest Release

v4.5.8 adds diff-scoped cr-agent semantic review, fixes nested repository diff lookups, and filters semantic findings to changed hunks so PR reviews stay focused on code that actually changed.

Detailed release history lives in CHANGELOG.md. The older README-embedded changelog is archived at archive/README_CHANGELOG_ARCHIVE.md.

FAQ

Is this only for MCP servers? No. It scans normal repos, diffs, prompts, actions, packages, SBOMs, MCP servers, and AI skills.

Does it send my source code anywhere? Rule-based CLI and MCP scans are local. cr-agent uses the provider you choose for semantic review.

Is it a replacement for npm audit? No. It complements npm audit by catching AI-specific risks: hallucinated packages, prompt injection, MCP tool poisoning, unsafe agent actions, and vulnerable generated code.

What should I run first? Run npx agent-security-scanner-mcp scan-project . --verbosity compact.
