What your AI can do with Astro API
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “astrologos.run”: Run an Astrologos program and return a job id plus sync output when available.”
“Use “astrologos.job_status”: Read the current status for one owned Astrologos job.”
“Use “astrologos.job_result”: Read stored stdout and stderr for one completed owned Astrologos job.”
“Use “astrologos.abort_job”: Request cancellation for one owned Astrologos job.”
How secure is the Astro API MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Astro API holds up.
Official endpoint
Operated by Astro API (197.155) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Astro API adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

The Astro API MCP server at a glance
https://81.166.197.155/mcpQuestions, answered
Is there an official Astro API MCP server?
Yes — Astro API operates its own remote MCP server at 81.166.197.155. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Astro API to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Astro API in the directory. No account or sign-in is needed. From then on, Astro API's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Astro API runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Astro API MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
