Summary
A dependency guardrail that validates packages before your AI agent installs them. It searches 6,500+ curated developer tools with real compatibility data scraped from 4,500+ GitHub repos, so you can ask "find an auth solution for Next.js" or "check if these two tools work together" and get install commands, health scores, and verified stack combinations. The 23 tools include package validation to catch hallucinations and typosquats, compatibility search with conflict warnings, project scanning for recommendations, and market gap analysis showing what developers search for but can't find. Runs via uvx with zero installation. Useful when your agent wants to add dependencies or when you're architecting features and need to know what already exists in the indie ecosystem.

Dependency guardrail for AI coding agents. Validates packages before installation, catches hallucinations and typosquats, and provides compatibility intelligence across 6,500+ developer tools.
10,000+ PyPI installs | 110,000+ unique visitors | 23 MCP tools
claude mcp add indiestack -- uvx --from indiestack indiestack-mcp
Then ask your agent:
- "Validate this package before installing"
- "Find an auth solution for my Next.js app"
- "Check compatibility between these two tools"
What it does
Before your AI installs a dependency or writes boilerplate — IndieStack validates it exists, checks for typosquats, and searches 6,500+ curated developer tools with real compatibility data from 4,500+ repos. You get install commands, health scores, and what tools actually work together in production.
"Indie" is the curation filter: independent developers and small teams. Focused, lean, maintained, honest pricing.
