Multi-User Shared Memory Server
Fresh-Comparison846 · reddit · 2026-07-17
The author released mwe-mcp 1.4, an MCP memory server designed for multiple users and agents to share, moving away from isolated "single-user memory."
Core Design
- A single memory pool shared by multiple users/agents, ideal for families or small teams
- Each fact includes its own governance metadata:
- Who the fact is about
- Who stated it
- Who can view it
- When it expires
- Pages can mix public, private, and group content; the system automatically redacts based on the reader's identity rather than relying on prompt-level instructions
Key Capabilities
- Agent-agnostic: Claude Code, voice assistants, and other agents can read/write to the same memory via MCP
- Memories are saved as Markdown files for easy diffing, backups, and manual review
- Each fact has a validity window (e.g., automatically disappears once a task is complete)
- Nightly routines handle deduplication, merging, recompilation, with a 7-day rollback option
- Version 1.4 allows users to continue the same conversation thread across different entry points, preventing the assistant from "amnesia" when switching surfaces
Current Status & Limitations
- A single Rust binary serves both /mcp and the admin panel
- Claude Code can connect via OAuth
- Semver is stable but not yet battle-tested
- The internal LLM requires a highly capable model; smaller models struggle with routing
- Windows version is available, but two recall tests are still best-effort
Repository: Fr4nZ82/mwe-mcp. The author is also seeking feedback on the actual governance needs when building multi-user assistants.
