Description from the maker (original English)
Persistent memory and virtual filesystem MCP server for AI agents.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
MEMOFS_API_KEY, MEMOFS_RUNTIME, AuthorizationValues marked secret are keys to your account. Never share them or paste them into a chat.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

@memofs/mcp-server
Model Context Protocol server for MemoFS agent integrations.
The @memofs/mcp-server package allows AI coding agents (like Claude Desktop, Cursor, Zed, and OpenCode) to securely read, search, and update project memory using the Model Context Protocol (MCP). It wraps the core runtime and exposes 10 model-facing tools (4 memory verbs + 6 AgentFS session tools) and 9 resources for memory, graph, and session access.
Key capabilities:
memofs.remember accepts an optional anchor parameter to bind memories to source files; memofs.recall surfaces stale flags when anchored files change.unverified flags when memories exceed their kind-specific decay floors.memofs_agent_session_complete accepts outcome, ephemeral, and reason parameters controlling a 5-row behavior matrix for durable memory promotion and workspace cleanup.Most MCP clients invoke the server on demand via npx — no install required:
npx -y @memofs/mcp-server --help
If you want to install the server as a dev dependency instead:
npm install -D @memofs/mcp-server
Requires Node.js >= 22.
Or use directly via npx in your client's configuration:
npx -y @memofs/mcp-server --help
You can configure your MCP client (e.g., Claude Desktop, Cursor, or any MCP client) to start the server via stdio.
{
"mcpServers": { "memofs": { "command": "npx", "args": [ "-y", "@memofs/mcp-server", "--runtime", "local", "--root", "/absolute/path/to/project" ] } } }
The server supports two runtime modes (local, hybrid), cloud sync via --cloud-url and --api-key, and a strict --read-only flag to block mutating tools when used with untrusted clients.
For comprehensive setup instructions across all major AI tools, the full list of exposed tools and resources, and runtime mode options, please refer to the Full Documentation.
See our central Contributing Guide and development scripts for details on formatting, linting, and testing within the monorepo.
