API

See docs-md.com/api-docs. Summary:

• POST /api/share — body {content, filename?, expiry?} where expiry ∈ 1d|7d|30d|never; returns {id, url, rawUrl, editToken, expiresAt} (expiresAt 0 = permanent)
• PATCH /api/share/:id — header x-edit-token, body {content, filename?}
• DELETE /api/share/:id — header x-edit-token
• GET /raw/:id — raw text/markdown

Indexing policy: only permanent shares are indexable; expiring shares are served with noindex.

MCP Registry

Published in the official MCP Registry as com.docs-md/markdown-share — remote streamable-HTTP server at https://docs-md.com/api/mcp with tools share_markdown, update_share, and delete_share.
