Looking for an alternative to Astral MCP? Whether you need a different runtime environment, custom authentication support, or alternative API integrations in the Spirituality & Esoterica ecosystem, we have cataloged and compared the top alternative MCP servers below.
Use the davidmosiah/astral-mcp MCP server to provide AI agents with locally computed natal charts, current transits, synastry comparisons, Moon phases, and birthplace coordinates. It runs without an API key, account, or OAuth, and cross-checks natal chart placements with two independent ephemerides. Birthplace lookup is the only optional network operation; other calculations run offline and the server stores no data. Reach for it when an agent needs structured astrology data rather than built-in interpretation text.
