ReactiveMemory MCP Server

ReactiveMemory MCP Server gives AI assistants a persistent, queryable, locally-stored memory system backed by vector search, a temporal knowledge graph, and a vault-structured content store. It is designed to be the durable external memory layer for agents, copilots, and AI workflows that need to remember, reason over, and navigate accumulated knowledge across sessions.

It is implemented in C# on net10.0 using ModelContextProtocol 1.2.0.

What ReactiveMemory helps with

Without persistent memory, every AI session starts from zero. ReactiveMemory solves this by giving agents a place to:

• Store any content — code snippets, decisions, meeting notes, design facts — under an organized sector/vault taxonomy
• Search across everything stored using semantic vector similarity, not just keyword matching
• Reason over time using a temporal knowledge graph that tracks when facts became true and when they were superseded
• Navigate the stored graph to discover how vaults relate to each other across sectors
• Log agent activity in per-agent diaries that persist session summaries across restarts
• Deduplicate incoming content before storing it to keep the core lean
• Audit every mutation via a JSONL write-ahead log

This server is intended for:

• AI coding agents that need to remember project context, architectural decisions, and code patterns across sessions
• Copilot workflows where facts discovered in one session need to survive to the next
• Long-running agent pipelines where temporal knowledge (facts with lifetimes) matters
• Multi-agent setups where a shared knowledge core is needed

Core concepts

ReactiveMemory organises everything into a four-level hierarchy:

Relays are internal metadata annotations on drawers that describe the relay channel (e.g. relay_diary, relay_code). They are used for graph construction and traversal but
