The most complete astronomical computation engine available as an MCP server. Open Ephemeris gives AI agents direct access to JPL DE440/DE441 ephemeris data — the same dataset used by NASA — for sub-a
Install
$ npx -y @smithery/cli@latest install open-ephemeris/openephemerisInstalling via npx/uvx/npm install executes arbitrary code from the public registry on your machine. This is the install-risk semantic of the MarketNow catalog — verify the publisher before running it.
How MarketNow scored this
Sentinel Index Heuristics — a security-first estimate from public signals:
- Package age and release activity (stale repositories lose points)
- Verified adoption: registry downloads or GitHub stars, not follower counts
- Typosquat distance against the 150 most-installed MCP packages
- Injection markers scanned in the package description
Heuristic, not a guarantee. For verified agent credentials and revocation, see the MarketNow Trust API.
What is open-ephemeris/openephemeris?
The most complete astronomical computation engine available as an MCP server. Open Ephemeris gives AI agents direct access to JPL DE440/DE441 ephemeris data — the same dataset used by NASA — for sub-a Indexed by MarketNow with trust 45/100 (Runs registry code).
How do I install it?
Run $ npx -y @smithery/cli@latest install open-ephemeris/openephemeris Installing via npx/uvx/npm install executes arbitrary code from the public registry on your machine. This is the install-risk semantic of the MarketNow catalog — verify the publisher before running it.
What does the trust score mean?
Security-first heuristic over public signals (age, adoption, typosquat distance, injection markers). It is not a popularity ranking and not a guarantee of safety. open-ephemeris/openephemeris scores 45/100.
