mycop vs Snyk — AI Code Security Scanner Comparison

TL;DR

mycop is a focused, free, open-source SAST scanner that finds vulnerabilities in AI-generated Python, JavaScript, TypeScript, Go, and Java code, with AI auto-fix and a built-in MCP server. Snyk is a comprehensive, commercial application security platform covering SAST, SCA (dependency scanning), container security, and IaC scanning across 10+ languages. Choose mycop for fast, zero-cost, AI-assisted code scanning with automatic remediation. Choose Snyk when you need a full AppSec platform with dependency analysis, container scanning, license compliance, and enterprise support.

Overview

mycop is an open-source, AI-powered code security scanner (SAST) written in Rust. It targets Python, JavaScript, TypeScript, Go, and Java with 200 built-in security rules covering OWASP Top 10 and CWE Top 25. Its distinguishing feature is AI-powered auto-fix: it can automatically rewrite vulnerable code using Claude, GPT-4, Ollama, or other providers, then verify the fix by re-scanning. It also includes a built-in MCP (Model Context Protocol) server for integration with agentic coding tools like Claude Code, Cursor, and Windsurf.

Snyk is a developer-first application security platform founded in 2015. It provides four core products: Snyk Code (SAST), Snyk Open Source (SCA/dependency scanning), Snyk Container (container image scanning), and Snyk IaC (Infrastructure as Code scanning). Snyk is widely adopted in enterprise environments and integrates deeply with developer workflows through IDE plugins, CI/CD pipelines, and SCM integrations. It offers a free tier for individuals and paid plans starting at $25/developer/month.

mycop: Pros and Cons

Strengths

  • AI-powered auto-fix with 5 provider options — automatically rewrites vulnerable code and verifies the fix
  • Completely free, MIT licensed — no feature gates, test limits, or paid tiers
  • No account required — install and scan without signup or authentication
  • Built-in MCP server for agentic tool integration (Claude Code, Cursor, Windsurf)

  • Works completely offline (no cloud dependency for scanning)

Limitations

  • SAST only — no dependency scanning (SCA), container scanning, or IaC scanning
  • Only supports Python, JavaScript, TypeScript, Go, and Java
  • No taint tracking or inter-file data flow analysis
  • No web dashboard, reporting, or centralized policy management
  • 200 rules vs Snyk's broader rule coverage with semantic analysis
  • No enterprise support, SLA, or compliance certifications
  • CLI-only — no native IDE extension yet (VS Code planned)
  • Newer project with smaller community

Snyk: Pros and Cons

Strengths

  • Comprehensive AppSec platform — SAST, SCA, container, and IaC in one tool
  • Industry-leading dependency vulnerability database with curated advisories
  • Automatic fix PRs for known dependency vulnerabilities
  • Snyk Code uses semantic analysis with data flow tracking for accurate SAST
  • 10+ language support for SAST, and broad ecosystem support for SCA
  • Mature IDE integrations (VS Code, IntelliJ, Eclipse, Visual Studio)
  • Web dashboard with project views, trends, priority scoring, and reporting
  • License compliance checking for open-source dependencies
  • Enterprise features: SSO, audit logs, custom policies, dedicated support
  • Large community, extensive documentation, proven in production at scale

Limitations

  • No true AI auto-fix — Snyk Code suggests fixes but does not auto-apply and verify them
  • Free tier is limited (e.g., 200 Snyk Code tests/month, limited projects)
  • Team plan costs $25/developer/month — significant cost for larger teams
  • Account and authentication required even for CLI usage
  • Proprietary engine — cannot audit or modify the analysis logic
  • Depends on cloud connectivity for vulnerability database and some features
  • No MCP server for agentic tool integration
  • SAST fix suggestions require manual developer effort to implement
  • Setup and configuration can be involved for enterprise deployments

Deep Dive: Key Differences

Scope: Focused SAST vs Full AppSec Platform

This is the most fundamental difference between the two tools. mycop does one thing: it scans source code for security vulnerabilities. It does it well, with AI auto-fix on top, but it is intentionally limited to SAST for Python, JavaScript, TypeScript, Go, and Java.

Snyk is a full application security platform. Beyond SAST (Snyk Code), it provides dependency vulnerability scanning (Snyk Open Source) that checks your package.json, requirements.txt, and other manifests against a curated vulnerability database. It scans Docker container images for OS-level and application-level vulnerabilities. It checks Terraform, CloudFormation, and Kubernetes manifests for security misconfigurations. If you need all of these capabilities under one roof, Snyk is hard to beat.

AI Auto-Fix vs Fix Suggestions

mycop's mycop fix command creates a complete automated remediation pipeline. It groups findings per file, sends them to an AI provider along with the full file context, receives corrected code, generates a diff for review, and optionally re-scans to confirm the vulnerability is resolved. The entire process can be run with --dry-run to preview changes before applying them.

Snyk Code provides fix suggestions — it shows you what kind of change to make — but the actual code modification is left to the developer. For dependency vulnerabilities, Snyk can automatically open fix PRs that bump a vulnerable package to a patched version, which is a genuinely useful workflow that mycop does not offer (since mycop does not do SCA).

Open Source vs Proprietary

mycop is fully open source under the MIT license. Every line of code, every rule, and every algorithm is available on GitHub. You can audit it, fork it, contribute to it, and deploy it anywhere without restrictions. There are no paid tiers or feature gates.

Snyk's CLI is open source (Apache 2.0), but the analysis engine, vulnerability database, and platform are proprietary. The free tier has usage limits (e.g., 200 Snyk Code tests per month for open source projects), and advanced features like custom rules, advanced reporting, and SSO require paid plans. This means your security scanning depends on Snyk's infrastructure and pricing decisions.

Pricing

mycop is free. All features, all rules, no limits. The only cost is an AI API key if you want to use the auto-fix feature with a cloud provider (and you can use Ollama for fully local, free auto-fix).

Snyk offers a free tier for individual developers and small open-source projects, but it comes with test limits and restricted features. The Team plan starts at $25/developer/month, and Enterprise pricing is custom. For a team of 20 developers, that is $500/month or $6,000/year — which may be justified by Snyk's breadth, but is a significant commitment.

MCP Server and Agentic Integration

mycop includes a built-in MCP (Model Context Protocol) server that exposes scan, review, explain, and other tools to agentic coding assistants. Claude Code, Cursor, Windsurf, Codex CLI, and Gemini CLI can invoke mycop directly within their conversation flow. The agent reads findings and applies fixes itself using the context from the scan.

Snyk does not currently offer MCP integration. It provides IDE extensions for VS Code and IntelliJ that show diagnostics inline, but there is no protocol for agentic tools to invoke Snyk's scanning programmatically within a conversation.

Setup Complexity

mycop is a single binary install. Run the install script, then mycop scan .. No account, no configuration file, no rule selection. It works immediately with 200 rules out of the box.

Snyk requires creating an account and authenticating (snyk auth) before you can run scans. For organizations, there is additional setup: connecting repositories, configuring integrations, setting up policies, and managing team access. The payoff is a more comprehensive and managed experience, but the initial setup investment is higher.
