Ground agents in verifiable planetary coordinates and distances so astronomy answers rest on computed ephemeris data, not recall.
Enable Planet Positions and it becomes a tool your agent calls over MCP to check itself against live data before it answers — grounding the response instead of guessing.
Planet Positions rides the one VerveContext MCP endpoint alongside 300+ other sources, so adding it to an agent is a toggle, not an integration.
The agent pulls planet positions at answer time and can carry the source with the result, so the reasoning stays current and auditable.
Point your agent framework at the VerveContext endpoint. Every enabled source — this one included — becomes a tool the model can call. No per-source plumbing.
