mwe-mcp — Claude Code MCP server: shared agent memory as Markdown
A self-hosted MCP server where agents write facts into one Markdown wiki, and access is decided for each fragment on its own.
Open on GitHubWhat mwe-mcp — Memory Wiki Engine 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.
What it helps with
- 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 for the agent
- 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.mdthe way Zoe would see it.

Questions about mwe-mcp — Memory Wiki Engine
How do I install mwe-mcp in Claude Code?
There is no install command for Claude — build the server from the Fr4nZ82/mwe-mcp repository and register it in your MCP configuration.
What does mwe-mcp do?
It holds shared memory for several agents as a Markdown wiki. Each fact on a page is indexed on its own, and the engine decides whether a given reader gets to see it.
How is this different from vector memory?
You can read the memory yourself, and access is limited to a single sentence inside a page rather than to a whole document.
