Copy this message into your AI

Connect AstroProcessor using https://mcp.astroprocessor.app/mcp and read the setup guide at https://astroprocessor.app/ai-connector

Then paste it into a chat with your AI.

Connect ChatGPT

Availability depends on your ChatGPT plan. In a Business or Enterprise workspace, an admin adds it.

  1. In ChatGPT on the web, open Plugins (chatgpt.com/plugins), click + and choose Add custom MCP server.
  2. Name: AstroProcessor. Server URL: https://mcp.astroprocessor.app/mcp. Authentication: OAuth.
  3. Tick “I understand and want to continue”, then click Create as a plugin.
  4. Install the plugin, then sign in with your AstroProcessor account and allow access.
  5. In a new chat, type @ and choose AstroProcessor.

Connect Claude

In a Team or Enterprise organization, an owner adds it in Organization settings → Connectors, and you click Connect.

  1. In Claude on the web or desktop, open Customize → Connectors, click + Add, then Add custom connector.
  2. Name: AstroProcessor. URL: https://mcp.astroprocessor.app/mcp. Keep the sign-in settings Claude finds, then click Add.
  3. Connect, then sign in with your AstroProcessor account and allow access.
  4. In a chat, turn AstroProcessor on under + → Connectors. It works on mobile too once it is added.

Connect Claude Code

  1. In a terminal, run: claude mcp add --transport http --scope user astroprocessor https://mcp.astroprocessor.app/mcp
  2. Start Claude Code (or restart it), run /mcp, choose astroprocessor and sign in.

Connect Gemini CLI

Gemini CLI is Google's app for the terminal, not the Gemini chat at gemini.google.com.

  1. In a terminal, run: gemini mcp add --transport http --scope user astroprocessor https://mcp.astroprocessor.app/mcp
  2. Start Gemini CLI with the gemini command, run /mcp auth astroprocessor, then sign in and allow access in your browser.

Check the connection

Then, in any app, ask: “What does my natal chart say about me?”.

Frequently asked questions

Do I need an AstroProcessor account?

Yes. The connector works with your AstroProcessor account: you sign in with it when your AI app asks, and the AI reads your own natal chart. If you do not have an account yet, create one at astroprocessor.app first.

Which AI apps can connect to AstroProcessor?

ChatGPT, Claude, Claude Code and Gemini CLI have their steps on this page. Any other MCP client connects with the same URL, over Streamable HTTP, with an OAuth sign-in.

Can the AI see my saved charts?

Not your saved charts. If you allow it on the consent screen when you connect, the AI reads your own natal chart, from the birth data in your profile, and computes from it: its forecast for any date, a relocation to another city, a synastry with a person whose birth data you give, your lunar return and the cities on your AstroMap lines. It uses them to answer questions about you. It never changes or deletes your charts, and it never reads your other charts, your chat threads or your notes. If your profile has no birth data, it can save the date, time and place you give it, once, and add your natal chart to your dashboard.

How do I disconnect an AI app?

In AstroProcessor, open Settings → Account and choose Disconnect beside the app. Removing the connector in the app itself works too.
