Fidelis Memory Overview

Fidelis Memory MCP server connects local agents to a machine-local store for saving and retrieving Markdown or text notes. It preserves stored wording on verbatim paths, while vector and optional hybrid retrieval help locate relevant passages. A local Ollama service supplies embeddings, and a background Fidelis service handles storage and retrieval after initialization. Reach for it when agents need durable, single-machine memory with access to the original note rather than only a generated summary.

Primary Use Cases for Fidelis Memory:
  • Recall exact conditions from prior engineering notes
  • Store local Markdown memory across agent sessions
  • Correct outdated memories while retaining history
  • Inspect retrieved notes and their validity status
