Connect the CEV-OS Data API over MCP

The CEV-OS Data API exposes the same 13 public products as read-only MCP tools on a stateless Streamable HTTP server.

Canonical URL: https://mcp.cev-os.com/mcp (POST only; GET returns 405 with a pointer).
Legacy alias: https://cev-os.com/mcp still accepts POST (Firebase Hosting rewrite to the same service). Prefer the canonical host in new configs.
Registry name: com.cev-os/data.

Claude Code (tested)

From a terminal, with Claude Code installed:

claude mcp add --transport http cev-os-data https://mcp.cev-os.com/mcp

Or add this block to .mcp.json in the project (or ~/.claude.json):

{
  "mcpServers": {
    "cev-os-data": {
      "type": "http",
      "url": "https://mcp.cev-os.com/mcp"
    }
  }
}

Cursor (tested)

Project file .cursor/mcp.json (Cursor Settings → MCP → add a new HTTP server if you prefer the UI):

{
  "mcpServers": {
    "cev-os-data": {
      "url": "https://mcp.cev-os.com/mcp"
    }
  }
}

Restart Cursor or reload MCP after saving. The server advertises 13 tools; a first tools/list should include get_macro_calendar and get_incident_assets.
