Overview

AI-generated overview

IndieStack lets an AI coding agent search a curated catalog of developer tools, validate packages before install, and check tool compatibility.

What you can do
  • Search and browse a catalog of developer tools with filters, tags, categories, curated stacks and recent additions
  • Inspect a tool's details, pricing, integration code, GitHub health and side-by-side comparisons
  • Validate packages before installation and analyze project dependencies for alternatives
  • Find compatible tools, build stacks, and report compatibility or usage outcomes back to the catalog
  • Scan a project description for recommendations, evaluate build-versus-buy cost, and publish a tool to the catalog
When to use it
Useful when an agent is about to add a dependency, choose a library or scaffold boilerplate and you want it to confirm the package exists, avoid typosquats, and pick tools that are known to work together.
Requirements
Runs locally over stdio via uvx (or pipx/pip) from the indiestack PyPI package, so Python and uv are needed. No API keys or environment variables are declared; the README mentions GitHub OAuth and Stripe on the hosted service side.
Before you install
Some tools write to the shared catalog: publish_tool submits a tool, and report_compatibility and report_outcome send compatibility and success/failure reports. get_recommendations uses your search history, and queries go to the hosted service. The README also mentions paid Stripe subscriptions on the service side.

Installation

In SourceWeft

  1. Open IndieStack in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

bash
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):

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

Claude Desktop — add to claude_desktop_config.json:

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

Cursor / Windsurf — add to your MCP config:

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

Persistent install:

bash
pipx install indiestackclaude mcp add indiestack -- indiestack-mcp

CLI (terminal use):

bash
pip install indiestack
indiestack search "analytics"indiestack details simple-analyticsindiestack stack "auth, payments, email"

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.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
