Publishes agent-written Markdown as a shareable link, using a secret gist through gh or a local SQLite server with passwords and expiry.

## What it does

Agents keep producing Markdown: reports, digests, meeting notes. Handing that to someone else usually means dumping a wall of text into chat. This stdio server exposes nine tools so the agent can create a document, append to it, rewrite the content, extend the deadline, change the password, rename, revoke, delete and search by text.

One interface, two backends, chosen by an environment variable. The `gist` mode needs no setup: the document lands in a secret gist via a `gh` CLI you already signed into, and the unguessable URL is the only protection. The `selfhost` mode keeps everything on your disk in SQLite, checks passwords with bcrypt, throttles failed attempts and enforces expiry. A backend that cannot honour a parameter reports an error rather than ignoring it.

Node.js 22.13 or newer is required; the gist path also needs `gh auth login`. The viewer answers on `127.0.0.1` only, so exposing a link externally takes a tunnel you set up. A daemon mode, `sharedoc-mcp serve`, keeps selfhost links alive once the MCP client exits.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `SHAREDOC_BACKEND`, `SHAREDOC_PUBLIC_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- hand off an agent report as one link instead of pasted text
- append new sections to a document that is already published
- lock a draft behind a password and an expiry date
- locate an old share link by its contents rather than its title
- rotate the password or revoke a document that went to the wrong person

## Example prompts
- Publish this report as a document and give me the link
- Find the document where I wrote up that incident
- Put a password on this document and set it to expire in a week
