IndieStack

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.

Prompts

What's new in v1.19

• Package validation — `validate_package()` verifies packages exist and are safe before installation. Catches hallucinated and typosquatted packages.
• Guardrail-first design — Built for AI agents that need to validate dependencies, not just discover them.

Recent highlights

• Migration intelligence — Tool details include real migration data from 4,500+ GitHub repos.
• 93,000+ verified package combinations from production repos.
• Trust-weighted search — Tools with higher agent success rates rank higher.
• Market gaps — `get_market_gaps()` exposes zero-result queries ranked by search volume.
