"Scratch" matching MCP servers:

Manages a global scratchpad file on your Desktop for tracking interruptions, ideas, tasks, and focus across all projects with secure input validation and rate limiting.

scratchpad-mcp is an MCP server that gives AI agents persistent, token-efficient storage. Eight tools versioned file writes, structured line-diffs since a prior version, append-only logs with cursor pagination, on-demand summaries with per-version caching, and per-agent quotas. The point is to stop agents from re-reading files they've already seen and re-summarizing documents.

A minimal MCP server built from scratch with no SDK, providing shell, file read/write, and URL fetch tools over Streamable HTTP and WebSocket.

Provides persistent agent workspaces with MongoDB storage for file management and real-time task progress tracking. It enables secure, isolated user environments with full activity logging for workspace operations.
