Overview

What is Aerostack Registry?

Aerostack Registry is a hosted MCP registry that lets AI agents discover and use 100+ MCP servers instantly via a single URL (mcp.aerostack.dev). It runs on Cloudflare’s edge with no local processes, Docker, or cold starts, and integrates with clients like Claude, Cursor, and Windsurf.

How to use Aerostack Registry?

Connect mcp.aerostack.dev to your AI client (e.g., Claude, Cursor, Windsurf). Your agent can then search the registry using search_registry, fetch tool schemas with get_tool_schema, and execute functions via call_function (requires a Bearer token). No installation or local configuration needed.
