# mwe-mcp — Memory Wiki Engine

A self-hosted MCP server where agents write facts into one Markdown wiki, and access is decided for each fragment on its own.

## What it does

mwe-mcp keeps agent memory in a folder of Markdown pages instead of a vector index. You can open the files, correct a wrong fact, or trace why an agent believes something. Below the pages sits an index: every fact carries a subject, a sender, an audience and a validity window.

Visibility is enforced fragment by fragment. A fact scoped to the `team` group never reaches someone outside it, because the engine strips the span before it gets to that person's agent. No error, no access-denied message — the text is simply absent. The rules live in engine code, not in a polite request to the model.

The server is written in Rust and needs version 1.88 or newer. License is AGPL-3.0. A public demo at `demo.contea.casa` is a frozen instance where you can enter as Bob, Alice or Zoe and watch the same page render differently for each. The demo is read-only and no agent can be attached to it.

## Requirements
- Needs: a prebuilt binary from the repository releases

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- share one agent memory across several people without exposing everything
- open the memory and fix a fact the assistant got wrong
- trace which person reported a fact and when
- revoke access to a fact after a group change, with no re-indexing
- collect what a voice assistant, a chat bot and a coding agent each recorded

## Example prompts
- Note in memory: Bob changed jobs, he is at AcmeCorp now. It is about Bob, scope it to `team`.
- What do you know about my current job?
- Show `kitchen_renovation_trades.md` the way Zoe would see it.
