Undisk MCP: safe file memory for AI agents.

Overview

AI-generated overview

Local stdio-to-HTTP bridge that connects MCP clients to Undisk, a hosted versioned file-storage service for AI agents.

What you can do
  • Bridges a local stdio MCP client to the hosted Undisk MCP server over HTTP.
  • Gives the assistant access to Undisk's 25 tools for file operations, version control, workspace administration, introspection and sandboxed compute.
  • Every write creates an immutable version, actions are audited, and changes can be reversed in a single call.
When to use it
Use it when your MCP client only speaks stdio (for example a Docker or local desktop client) but you want the hosted Undisk file-memory service with versioned, auditable, reversible file changes.
Requirements
Runs as a local npm package (@undisk-mcp/stdio-proxy) on the user's machine, so Node.js is needed. Requires an Undisk API key supplied in the UNDISK_API_KEY environment variable, obtainable by signing up on the Undisk site. Network access to the hosted Undisk service is required. Desktop only.
Before you install
The API key in UNDISK_API_KEY is a secret that grants access to your Undisk workspaces; keep it out of shared configs and logs. The assistant can write files and run sandboxed compute through the hosted service, so changes affect stored data, though versions are immutable and reversible. File contents are sent to the third-party Undisk service.

Installation

In SourceWeft

  1. Open Stdio Proxy in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
