Deterministic tech stack recommendations, audits, and project estimates. No hallucinations.

Get deterministic tech stack recommendations and project estimates.

@stacksfinder/mcp-server

MCP (Model Context Protocol) server that brings deterministic tech stack recommendations to LLM clients like Claude, Cursor, Windsurf, and other MCP-compatible tools.

Try it free — 8 tools work without an account, including a daily demo recommendation and MCP project kit.

Quick Start

Claude Code (CLI)

bash

# macOS/Linux
claude mcp add stacksfinder npx -y @stacksfinder/mcp-server

# Windows (requires cmd wrapper)
claude mcp add-json stacksfinder '{
  "command": "cmd",
  "args": ["/c", "npx", "-y", "@stacksfinder/mcp-server"],
  "env": {"STACKSFINDER_API_KEY": "sk_live_xxx"}
}'

# With API key (macOS/Linux)
claude mcp add-json stacksfinder '{
  "command": "npx",
  "args": ["-y", "@stacksfinder/mcp-server"],
  "env": {"STACKSFINDER_API_KEY": "sk_live_xxx"}
}'
