Celestio

Celestio's remote MCP server lets AI assistants calculate a birth chart for any date from 1900 to 2100 and any place in the world, with optional birth time, and return a personal AI-written astrology reading. It is published by Cuesta Technologies LTD (Bulgaria), the maker of celestio.ai. Astrology is offered as interpretation and entertainment, not scientific fact.

Celestio for assistants

Use Celestio in your AI

Ask your assistant for a birth chart, a personal reading or a compatibility report, and Celestio does the astrology. Your readings land in your Celestio account, so they’re here on the site too.

Celestio’s address for assistants

Paste this wherever your assistant asks for a connector or MCP server URL.

https://celestio.ai/mcp

Charts work straight away. For readings and your library, your assistant asks you to sign in to Celestio (or create a free account) once.

  • Claude Code, Codex, Cursor and Gemini CLI

    Add the server from your terminal:

    claude mcp add --transport http celestio https://celestio.ai/mcp

    codex mcp add celestio --url https://celestio.ai/mcp

    gemini mcp add --transport http celestio https://celestio.ai/mcp

    In Cursor, add "celestio": { "url": "https://celestio.ai/mcp" } under mcpServers in your MCP settings.

Things to ask

  • “Draw my birth chart: 15 June 1990, 2:30 pm, Sofia.”
  • “Write my birth chart reading and save it to Celestio.”
  • “What did my last Celestio reading say about work?”
  • “How compatible are Maya and Sam? Here are their birthdays…”

Compatibility reports bought from a chat are paid on Celestio’s secure Stripe checkout, and the report appears in your readings. Developers can also use the Celestio API.
