mdshare — markdown sharing via MCP

mdshare is a free, no-login markdown sharing service at mdshare.live. This skill orchestrates 14 MCP tools that let Cursor upload, read, edit, comment on, and version markdown documents.

When to use

• The user has a markdown file or just-generated markdown content they want to share
• The user wants link-based collaboration (comments, edit permissions, real-time sync)
• The user mentions mdshare specifically

When NOT to use

• The user wants Cursor to read or edit local markdown files (use the standard file tools)
• The user wants to configure Cursor with markdown context (.cursorrules, .cursor/commands/, AGENTS.md territory — different concept)
• The content is sensitive — share links are the only auth; warn the user instead

Core conventions

• All arguments are literal strings. Shell substitution like $(cat file) does NOT work.
• For files on disk, prefer `file_path` / `output_path`. Inline content over ~1KB burns tokens unnecessarily.
• `key` is OPTIONAL on tools addressed by `document_id` — admin keys are looked up automatically from the local credential store.
• Never surface admin URLs to the user unless they explicitly ask. upload_markdown returns only share_url by design.
• For small edits, prefer `patch_document` over `update_document` — keeps version history granular.

Tool reference

Sharing a new document

• upload_markdown(file_path) — preferred; pass disk path so content never enters conversation context
• upload_markdown(content) — fallback for inline content under ~1KB

Returns share_url. Admin URL is stored locally; surface only if explicitly asked via get_admin_url(document_id).

Editing an existing document

• patch_document(document_id, operations) — preferred for small edits (find/replace operations)
• update_document(document_id, file_path) — for whole-doc rewrites; pass file_path not content

Generating links with specific permissions

• generate_link(document_id, permission) — permission is one of admin, edit, comment, view
• revoke_link(token) — invalidate a specific link
• list_links(document_id) — see all active links

Comments

• post_comment(document_id, content, anchor_text?) — anchor_text creates an inline-anchored comment
• list_comments(document_id) — read the thread
• resolve_comment(comment_id) — mark resolved (drops the in-document highlight)

Discovery

• list_my_documents() — all documents uploaded via this MCP server
• register_document(admin_url) — import an admin URL from elsewhere
• read_document(document_id, output_path?) — fetch content; pass output_path for documents over 10KB

Versions

• get_versions(document_id) — see edit history

Caveats

• Documents expire after 90 days
• Anyone with a share link can access at the link's permission tier — don't paste sensitive content
• Free service with no accounts; not a Google Docs replacement
