emem

Présentation

emem is a shared memory for AI agents, filled with satellite, elevation, water, air quality and other geospatial readings. Each place gets one address (cell64) and each observation is a signed fact with a content hash, so two agents can cite the same fact and check the signature without trusting each other. Tools cover place lookup, fact recall, entity identities, citation tokens, receipt verification, contradiction scans and similarity search.

The hosted endpoint at emem.dev/mcp uses streamable HTTP and needs no sign-in or API key for reads. Writes to shared spaces are tiered and need a signature. The server also ships as a Docker image (ghcr.io/vortx-ai/emem) and exposes a short tool list plus emem_tools to discover the rest.

Ce que vous pouvez faire

• Resolve a place name or coordinates to a canonical cell64 address
• Recall signed facts for a place and band, with auto-materialization
• Mint and resolve emem:fact: citation tokens
• Verify receipts and check claimed values against signed facts
• Scan for disagreement between attesters on the same place and band
• Mint and resolve canonical entity identities for real-world objects
• Find similar places by embedding
• Ask free-text questions about a location
