This server solves the context compression amnesia problem in long-running Claude workflows by anchoring every step to an external cryptographic timestamp. When Claude compresses your chat history, agents call pot_query with an eventId and get O(1) exact retrieval of what happened before. The five tools include pot_generate to stamp workflow steps, pot_graph to traverse causal chains backward and forward, and pot_checkpoint to roll up history before token limits hit. Built on the IETF draft TTTPS spec with SHA-3 event IDs and Ed25519 signatures. Free tier gives you 100 calls per day with no signup. Reach for this when you're running multi-session refactors, deployments, or any workflow where losing state between compressions would cost you hours of reconstruction.
