awesome-mcp-dev-stack-selector

🚀 Executive Summary & Value Proposition

Traditional "Awesome" markdown lists on GitHub are static text documents: they suffer from dead links, unverified command lines, lack of machine readability, and zero contextual utility inside modern AI coding workflows.

awesome-mcp-dev-stack-selector bridges crowd-sourced community curation with AI developer tooling by providing an interactive Model Context Protocol (MCP) server and live catalog web application.

🌟 Key Value Highlights

• ⚡ 0ms Zero-Latency Cold Start: Starts instantly in 0ms using a Tier-1 NPM package bundled snapshot, backed by local disk caching and non-blocking background ETag sync.

• 🤖 AI-Agent Context Native: Allows Antigravity, Cursor, Claude Desktop, VS Code, and Windsurf to query tools, read resources, and execute workflow prompts directly inside agent loops.

• 🛡️ Supply-Chain Command Sanitization: All community PRs undergo strict Regex validation in CI to eliminate malicious shell command injection risks (brew install, winget install).

• 🔍 BM25 & Capability Search: In-memory relevance engine capable of matching natural language query intents like "offline vector editor capable of SVG export".

• 🔄 FOSS Commercial Replacement Mapping: Instant mapping from proprietary commercial software (Postman, Notion, Photoshop, Docker Desktop, Firebase) to verified open-source alternatives.

⚡ Agent Setup & Configuration

Add the MCP server to your AI coding environment zero-install using npx:

1. Antigravity & Claude Desktop

Add to claude_desktop_config.json or Antigravity MCP Settings:

{
  "mcpServers": {
    "dev-stack-selector": {
      "command": "npx",
      "args": ["-y", "@awesome-mcp-dev-stack-selector/mcp-server"]
    }
  }
}

2. Cursor IDE

Go to Settings ➔ Features ➔ MCP and add a new MCP Server:

• Name: dev-stack-selector

• Type: command

• Command: npx -y @awesome-mcp-dev-stack-selector/mcp-server

3. VS Code / Windsurf

Add to your workspace .mcp.json:

1. MCP Tools Surface (Executable Functions)

🔹 search_free_apps

Search free/FOSS software using natural language keywords, category, platform, or capability flags.

• Parameters:

  • query (string, optional): Keyword, app name, or capability (e.g. offline-editing, local-llm).

  • platform (string, optional): macOS | Windows | Linux

  • category (string, optional): developer-tools | ai-tools | container-infra | design-media | productivity

  • capability (string, optional): Specific capability requirement (e.g. git-versioning).

  • offline_only (boolean, optional): Filter for apps usable 100% offline.

• Example Payload:

{
  "total_found": 1,
  "apps": [
    {
      "id": "bruno",
      "name": "Bruno",
      "tagline": "Fast, offline-first, Git-friendly open-source API client",
      "license": "MIT",
      "website": "https://www.usebruno.com",
      "capabilities": ["offline-editing", "git-versioning", "scripting"],
      "replaces": ["postman", "insomnia"],
      "installation": { "macOS": "brew install bruno", "Windows": "winget install Bruno.Bruno" },
      "security_verified": true,
      "relevance_score": "10.00"
    }
  ]
}

🔹 get_app_details

Retrieve complete metadata, license status, self-hosting configurations, and migration notes for a specific app ID.

• Parameters:

  • app_id (string, required): Unique identifier of the app (e.g. bruno, vscodium, ollama, podman).

🔹 find_foss_alternative

Locate FOSS/free replacements for commercial proprietary software with migration difficulty and import capability assessment.

• Parameters:

  • paid_software (string, required): Name of commercial software to replace (e.g. postman, vscode, photoshop, docker-desktop, firebase).

2. MCP Resources Surface (Read-only Context Loading)

AI Agents can read structured dataset resources directly into context without invoking tool steps:

• devstack://registry: Returns the complete aggregated application registry JSON.

• devstack://categories: Returns structured taxonomy breakdown with entry counts per category.

• devstack://app/{id}: Direct entity URI lookup for individual apps (e.g. devstack://app/bruno).

3. MCP Prompts Surface (Reusable Agent Workflows)

• audit_project_dependencies_for_foss: Scans workspace configuration files (package.json, docker-compose.yml) and prompts the AI agent to audit proprietary dependencies and suggest open-source replacements.

• recommend_open_source_stack: Prompts the AI agent to query the registry and recommend a 100% open-source software stack tailored to specific application requirements.

3-Tier Caching Rationale

1. Tier 1 (Bundled Snapshot): Ships compiled inside the NPM package so the MCP server initializes in 0ms even with zero internet connectivity.

2. Tier 2 (Disk Cache): Caches fetched registry datasets in ~/.cache/awesome-mcp-dev-stack-selector/registry.json with a 24-hour TTL.

3. Tier 3 (Background Sync): Issues non-blocking HTTP HEAD requests to GitHub Pages to check for dataset ETag changes without delaying tool execution.

🛡️ Supply-Chain Safety & CI Governance

Community pull requests submitting new apps in apps/**/*.json must adhere to strict security guardrails:

• Schema Validation: Verified against JSON Schema draft 2020-12 using Ajv.

• Safe Installation Command Regex: Package manager installation strings are strictly validated against approved patterns (brew install [a-z0-9-]+, winget install [A-Za-z0-9\.-]+, snap install [a-z0-9-]+).

• Forbidden Operators: Shell chaining operators (&&, ;, ||, backticks, subshells) are strictly forbidden to protect developer environments against Remote Code Execution (RCE).

• 3-Strike Circuit Breaker Audit: Nightly health checks require 3 consecutive failures over 48 hours before marking an app degraded, preventing false positives.
