Jotbus: a simple end-to-end-encrypted MCP scratchpad for cross-machine coding agents
Launchable-AI · reddit · 2026-10-09
Tired of shuttling files and hand-off notes between machines via throwaway repos, S3 buckets and gists, a developer built Jotbus — a minimal end-to-end-encrypted MCP scratchpad that lets coding agents (Claude Code, Codex, Cursor, OpenCode) share context and files across machines and teammates.
- npx jotbus installs the tool, configures your chosen agents' tools/hooks, generates a local encryption key (servers only see fingerprints), and creates a temp workspace
- Free 60-minute ephemeral workspaces; the join command lets a second agent on another machine start collaborating
- Designed Unix-style as a pure message bus, not an orchestration framework; suited for transient artifacts like agent-written specs, screenshots and logs
