Planetary positions, Moon phase and the coming week's sky events for a date (?date=YYYY-MM-DD, today by default).

One place against one chart: the relocated angles, the planets on them with orbs, a score for each life sphere and an overall score. (API Pro)

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "astrology": {
      "type": "http",
      "url": "https://www.natalchart.ai/mcp"
    }
  }
}

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
