Dev builds three-tool MCP server turning agent output into private, self-expiring links
Hopeful-Business-15 · reddit · 2026-09-12
The author built ShareBit, an MCP server for a common annoyance: agent outputs (plans, logs, JSON, code reviews) usually end up copy-pasted into public pastes. It exposes just three tools: create, list, read. After a one-time pairing, an agent can turn output into a private link that expires by default in 30 minutes (24h max), capped at 10 MB, readable only by the owner's account with no public mode, and each agent can be revoked individually. The author is upfront about two limits: the server cannot verify a human actually approved an upload (approval is guidance, not enforcement), and there is no end-to-end encryption, so it's not for secrets.
