StacksFinder MCP

Q: What's the difference between free and Pro tools?

Free tools (list_technologies, analyze_tech, compare_techs, recommend_stack_demo) let you explore and evaluate technologies. Pro tools unlock full stack recommendations, blueprint generation, technical debt audits, and API key management. Free users get 1 demo recommendation per day.

Q: Do I need an API key to use the MCP?

Free tools work without an API key. For Pro tools, you'll need a StacksFinder Pro subscription and an API key. You can generate one from your dashboard or using the setup_api_key tool.

Q: How does the scoring work?

Our scoring engine uses deterministic algorithms with versioned lookup tables, not LLM opinions. Technologies are evaluated across 6 dimensions: Ecosystem, Maturity, Velocity, Scalability, DX, and Community. Scores are reproducible and explainable.

Q: Can I use this with Claude, Cursor, VS Code, and Windsurf?

Yes. The StacksFinder MCP works with any MCP-compatible client including Claude Desktop, Claude Code, Cursor, VS Code with GitHub Copilot, Windsurf, and more. Just add it to your MCP configuration.

Q: What technologies are covered?

We cover 100+ technologies across 8 categories: Frontend frameworks, Backend, Meta-frameworks, Databases, ORMs, Auth, Hosting, and Payments. We continuously add new technologies based on community feedback.

Q: How accurate are the technical debt audits?

Audits analyze your package.json against multiple data sources: npm registry for deprecations, GitHub for security advisories, and our compatibility database. Results include a health score and actionable recommendations.

The official StacksFinder MCP server. Get deterministic tech stack recommendations, compare technologies, create blueprints, and audit technical debt - all from your AI coding assistant.

100% Transparent Scoring

This score uses the same simplified algorithm as all MCPs in our catalog. When full 5-dimension scoring is implemented, all MCPs (including StacksFinder) will be updated together.

Why StacksFinder MCP?

Data-driven recommendations, not LLM opinions

Core Principle

Deterministic Scoring

Our recommendations come from versioned lookup tables and mathematical formulas, not LLM opinions that change with every prompt.

Same input = same output, always

100+ Technologies

Comprehensive coverage across frontend, backend, databases, auth, hosting, and more. All scored on 6 dimensions.
