MANNA runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 16 Sep 2026.
MCP server for IVOA astronomical archives: NOIRLab Astro Data Lab, NRAO/ALMA, CADC, ESO, Gaia
Today is the operative word: we check MANNA every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
MANNA_ARCHIVES (Comma-separated archive short_names to activate (e.g. 'datalab,alma'). Unset means all.), MANNA_ALLOWED_HOSTS (Comma-separated hostnames the server may fetch. Unset means any public host.), MANNA_LOG_LEVEL (Logging verbosity.), MANNA_INLINE_ROW_LIMIT (Max rows returned inline before a result is promoted to an async job or truncated.).
The author declared them in the registry entry; get the values from the project itself.
