engram-mcp vs perseus-vault

engram-mcp: Engram is an MCP server that provides persistent, Git-aware session memory for coding agents, allowing structured handoffs between sessions and branches. It helps agents retain context, decisions, and tasks, backed by local SQLite and ONNX embeddings without cloud dependencies.; perseus-vault: Perseus Vault provides durable, encrypted, local-first memory for AI agents, operating as a single Rust binary with zero dependencies. It integrates seamlessly with popular AI agent frameworks like LangGraph, CrewAI, and AutoGen, offering advanced features like hybrid semantic search, bitemporal queries, and a robust memory lifecycle.

Features

engram-mcp logoengram-mcp
01Provides Git-aware session memory that scopes context to specific git branches, preventing information leakage.
02Enables structured session handoffs to capture summaries, decisions, todos, blockers, and mental models for continuity.
03Offers local-first persistent storage using SQLite and ONNX embeddings, ensuring no cloud or LLM calls are needed for storage.
04Features advanced memory retrieval with hybrid scoring (cosine, recency, importance), hierarchical clustering, and branch-aware queries.
05Includes automated memory management capabilities such as decay, semantic deduplication, and auto-pruning of low-relevance memories.
perseus-vault logoperseus-vault
01Bundled semantic search with zero configuration and network dependencies.
02Biomimetic memory lifecycle with Ebbinghaus decay, layer promotion, and automatic archiving.
03AES-256-GCM transparent encryption for stored entity data.
04Recall-first context injection with relevance gating and per-model budget.
05Multiple transport options including stdio, SSE, and HTTP for MCP clients.

Use Cases

engram-mcp logoengram-mcp
↳Developers can capture session state and structured notes (decisions, todos, blockers) at the end of a coding session for seamless handover.
↳Automatically retrieve relevant context and prior session details when resuming work on the same or a different Git branch.
↳LLM agents can proactively load relevant memories at the start of a conversation, building context from recent Git activity.
↳Passively capture coding decisions and session summaries into memory through integrated hooks without explicit tool calls.
↳Maintain a centralized, searchable, and structured memory of project-specific decisions, recurring patterns, and past debug solutions.
perseus-vault logoperseus-vault
↳Provide durable, persistent memory for AI agents across sessions.
↳Integrate as a memory backend for popular AI agent frameworks (e.g., LangGraph, CrewAI, AutoGen).
↳Export AI agent memories to Personal Knowledge Management (PKM) tools like Obsidian for human review and navigation.
↳Secure, air-gapped deployments requiring local-first operation and data privacy.
