staxly-mcp

MCP server that exposes the Staxly catalog of 129 developer platforms — BaaS, databases, auth, hosting, AI APIs, payments, CI/CD, commerce, docs, design, secrets, scheduling, project management, API clients, forms, UI kits, and more — to Claude Code, Cursor, Zed, and any other MCP-compatible AI agent.

Instead of asking the model to recall pricing or limits (which change often and are hallucinated frequently), the model queries a curated Postgres database for structured, up-to-date data: pricing tiers, quota limits, features, SDKs, REST endpoints, and even a monthly-cost estimator.

Install

npm install -g staxly-mcp        # or use npx directly in your MCP config

Configure in Claude Code

Add with the CLI:

claude mcp add staxly --scope user -- npx -y staxly-mcp

Or manually in ~/.claude/settings.json:

{
  "mcpServers": {
    "staxly": {
      "command": "npx",
      "args": ["-y", "staxly-mcp"]
    }
  }
}

Configure in Cursor / Zed / generic MCP

{
  "mcpServers": {
    "staxly": {
      "command": "npx",
      "args": ["-y", "staxly-mcp"]
    }
  }
}

Tools

| Tool | What it does | |---------------------|------------------------------------------------------------------------| | list_platforms | Browse catalog, filter by category (baas, dbaas, ai-coding, …) | | get_platform | Full details: interfaces, tiers, limits, features | | compare_platforms | Side-by-side comparison for 2–6 platforms | | get_pricing | Pricing tiers for one platform (monthly/annual USD + included quotas) | | get_limits | Quotas, rate limits, hard caps, overage rates | | search_features | Find platforms that ship a named feature (e.g. "vector search") | | list_operations | CLI commands, SDK calls, REST endpoints for any platform | | estimate_cost | Project monthly USD cost given MAU, storage, bandwidth, fn calls |

Example prompts

"I'm building a chat app expecting 20k MAU and 10 GB storage. Compare monthly cost across Supabase, Firebase, and Convex."

(Agent calls estimate_cost + get_limits → answers with real numbers.)

"Which BaaS platforms have native vector search?"

(Agent calls search_features with query="vector".)

"Show me every CLI command available in Supabase."

(Agent calls list_operations with platform=supabase, interface_slug=cli.)

"What is the cheapest Postgres with branching support, and what does it cost at 10 GB of storage?"

(Agent calls list_platforms → get_limits → estimate_cost chain.)

Environment

• STAXLY_DATABASE_URL — Postgres connection to the Staxly catalog. Defaults to the public read-mostly mirror (no setup needed).
• MACHETE_DATABASE_URL — legacy name, still supported for backward compatibility.

Development

git clone https://github.com/staxlydev/staxly-mcp
cd staxly-mcp
npm install
node test.js      # smoke-test all tools against live DB
node server.js    # run over stdio (for manual MCP-client testing)
