I built a three-tool MCP server that turns agent output into a private, expiring link

Most of my agents finish with something worth reading: a plan, logs, JSON, a code review. Moving that into a browser usually means copy-pasting it into a public paste, or another chat. Public by default, and permanent. ShareBit is my fix. An agent pairs once, shows a preview, and after I approve it, the output becomes a private link that expires on its own. Three tools only: create, list, read. 30 minutes by default, 24 hours maximum, 10 MB per share. Only my account can read a paste, and there is no public mode. Revoke an agent on its own. Two things I stay honest about: the server cannot verify that a human approved an upload, so approval is guidance rather than enforcement, and it is not encrypted end to end, so not for secrets. How do you handle this handoff in your own agents? I will drop the links in the comments.
