What can you do with IndieStack?

  • 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.

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package indiestack
Claude Code 
claude mcp add indiestack -- uvx indiestack==1.12.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "indiestack": {
            "command": "uvx",
            "args": [
                "indiestack==1.12.0"
            ]

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.

Tech stack

  • Backend: Python 3 / FastAPI / SQLite (FTS5 full-text search, WAL mode)
  • Infrastructure: Fly.io / Docker / 48-endpoint smoke testing
  • MCP server: Published on PyPI — 23 tools, 3 resources, 5 prompts
  • Auth: GitHub OAuth via sessions
  • Payments: Stripe subscriptions
  • Monitoring: Event reactor, pattern detection, Telegram alerting

Install

Claude Code (zero install — runs via uvx):

claude mcp add indiestack -- uvx --from indiestack indiestack-mcp

Claude Desktop — add to claude_desktop_config.json:

{
  "mcpServers": {
    "indiestack": {
      "command": "uvx",
      "args": ["--from", "indiestack", "indiestack-mcp"]
    }
  }
}

Cursor / Windsurf — add to your MCP config:

{"command": "uvx", "args": ["--from", "indiestack", "indiestack-mcp"]}

Persistent install:

pipx install indiestack
claude mcp add indiestack -- indiestack-mcp
