What it does

Celestio is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

compare_birth_charts · Compatibility between two people (partners, crushes, friends, family) from their names, birth dates, places and, if known, times. No account needed and nothing is saved. Returns the strongest connections between the two charts and compatibi

preview_transits · Calculates a free personal 30-day Transit preview for exactly one chartId OR person (birth details). Requires createReadings and may save a chart. An omitted start defaults to today in the birthplace timezone; returns literal civil dates, s
preview_compatibility · Free compatibility preview for two people: saves both charts in the connected Celestio account and returns the strongest connections between them.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
