Environment variables

Configuration this server reads at startup.

  • SYNAPSE_AGENT_ID

    Identifier for the agent using the memory layer (e.g., claude-desktop, my-agent).

  • SYNAPSE_PRIVACY_EPSILON

    Differential privacy epsilon parameter. Lower values = stronger privacy. Range: 0.1–2.0.

  • SYNAPSE_ENCRYPTION_KEYSecret

    AES-256-GCM encryption key for at-rest memory encryption. Auto-generated if not provided.

  • LOG_LEVEL

    Logging verbosity: DEBUG, INFO, WARNING, ERROR. Default: INFO.

Synapse Layer — Zero-Knowledge Memory MCP server — FAQ

Common questions about connecting and running Synapse Layer — Zero-Knowledge Memory.

  • What does Zero-Knowledge Context mean in this MCP server?

    Zero-Knowledge Context™ means the memory layer can verify and use encrypted agent context without decrypting or exposing the underlying data. Your sensitive conversation history stays encrypted at rest and in transit.

  • How do I set the privacy level for my agent?

    Use the SYNAPSE_PRIVACY_EPSILON environment variable (range 0.1–2.0). Lower values like 0.1 provide stronger differential privacy guarantees; higher values like 2.0 allow more utility but less privacy. Start with 0.5 for balanced protection.

  • Do I need to provide my own encryption key?

    No. If you don't set SYNAPSE_ENCRYPTION_KEY, the server auto-generates an AES-256-GCM key for you. You can supply your own key for key management integration with your infrastructure.

  • What is Neural Handover and when would I use it?

    Neural Handover™ is the mechanism for securely transferring context between AI agents without exposing raw memory. Use it when routing tasks between specialized agents or when handing off conversation state while maintaining privacy guarantees.

  • How do I troubleshoot memory encryption or privacy issues?

    Set LOG_LEVEL=DEBUG to see detailed encryption and differential privacy operations. Check that SYNAPSE_AGENT_ID is unique per agent and SYNAPSE_ENCRYPTION_KEY is consistent across restarts to avoid decryption failures.
