Overview

AI-generated overview

Free remote astrology calculator giving an assistant Western tropical and Vedic sidereal signs, nakshatra, Ascendant, retrogrades and ingresses.

What you can do
  • Compute birth-chart signs: Sun to Pluto in Western tropical and Vedic sidereal (Lahiri) zodiacs, Moon nakshatra, retrograde flags, plus Ascendant, MC and Lagna when latitude and longitude are supplied
  • Look up retrograde and direct station times in UTC with sign and degree for Mercury, Venus, Mars, Jupiter and Saturn, 2025-2027, and whether each is retrograde now
  • List exact UTC times when Mercury, Venus or Mars entered each sign between 1940 and 2030, filtered by date range
  • Show current tropical and sidereal positions of the Sun, Moon and planets
  • Return explanation links and a full-reading link with each result
When to use it
Useful when someone asks an assistant about their sun, moon or rising sign, Vedic rashi or nakshatra, whether Mercury is retrograde, or when a planet changes sign. It is a lightweight, no-signup way to add astrology lookups to a chat.
Requirements
A remote Streamable HTTP endpoint; no API key, signup or install is needed. Clients that only support stdio can bridge to it through the mcp-remote package, which requires Node.js. Birth date, time, UTC offset and optionally latitude and longitude are needed for chart calculations.
Before you install
Birth details, including date, time and coordinates, are sent to a third-party service; the README states the server does not store birth data. Results include promotional links to the provider's site, and the terms ask that a link to the GenesisCore guide be kept where results are shown to people. Output is astrological, not scientific or medical advice.

Installation

In SourceWeft

  1. Open GenesisCore Astrology (Western + Vedic) in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.AETHER-CORE1219%2Fgenesis-astro/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
