SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MNEMOS provides a persistent memory infrastructure for Hermes, enabling a shared memory pool across profiles and cross-session recall.

Core Features & Use Cases

  • Persistent cross-profile memory pool for Hermes.
  • Full-text and semantic search over memories, with knowledge-graph integration.
  • Ingestion of session transcripts and decisions for later retrieval and auditing.
  • Compression manifests and temporal validity for memory entries.

Quick Start

Configure MNEMOS as an MCP server for Hermes and point Hermes at MNEMOS_BASE to begin memory ingestion and retrieval.

FAQPage Schema
How do I enable persistent cross-session memory for Hermes?▼

Persistent cross-session memory for Hermes is enabled by configuring MNEMOS as an MCP server and pointing Hermes at MNEMOS_BASE to start ingesting and retrieving session data.

Can I search across multiple profiles in a shared memory pool?▼

Yes, you can perform full-text and semantic search across multiple Hermes profiles within a shared MNEMOS memory pool, retrieving cross-profile decisions and transcripts.

What is the best way to store session transcripts for later auditing?▼

Storing session transcripts for auditing is handled by ingesting them into the MNEMOS pool, which applies compression manifests and tracks temporal validity for memory entries.

Does MNEMOS support knowledge-graph integration with versioning?▼

Yes, MNEMOS supports knowledge-graph integration with versioning, allowing you to map relationships between memories and track changes over time within the infrastructure.

How do I isolate memory namespaces for different Hermes profiles?▼

Namespace isolation is implemented directly within the MNEMOS MCP server registration flow, ensuring memory write and read operations remain separated across different Hermes profiles.

Why do I need a shared memory pool for cross-session recall?▼

A shared memory pool solves the problem of context loss between sessions by allowing Hermes to access previously recorded decisions, patterns, and transcripts across all profiles.
