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** — 4 tools work without an account, including a daily demo recommendation.
## Quick Start
### Claude Code (CLI)
```bash
# Add to Claude Code
claude mcp add stacksfinder npx -y @stacksfinder/mcp-server
# With API key for full features
claude mcp add-json stacksfinder '{
"command": "npx",
"args": ["-y", "@stacksfinder/mcp-server"],
"env": {"STACKSFINDER_API_KEY": "sk_live_xxx"}
}'
```
### Claude Desktop
Add to `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows):
```json
{
"mcpServers": {
"stacksfinder": {
"command": "npx",
"args": ["-y", "@stacksfinder/mcp-server"],
"env": {
"STACKSFINDER_API_KEY": "sk_live_xxx"
}
}
}
}
```
### Cursor / Windsurf
Add to `.cursor/mcp.json` or `.windsurf/mcp.json` in your project root:
```json
{
"mcpServers": {
"stacksfinder": {
"command": "npx",
"args": ["-y", "@stacksfinder/mcp-server"],
"env": {
"STACKSFINDER_API_KEY": "sk_live_xxx"
}
}
}
}
```
### VS Code + Copilot
Add to `.vscode/mcp.json`:
```json
{
"servers": {
"stacksfinder": {
"command": "npx",
"args": ["-y", "@stacksfinder/mcp-server"],
"env": {
"STACKSFINDER_API_KEY": "sk_live_xxx"
}
}
}
}
```
