Upload markdown to mdshare and receive a shareable link. The response contains a read/comment/edit share link (default permission: comment) that the user can share with others. The admin credential (full control) is stored locally in ~/.mdshare-mcp/documents.json and is NOT returned in this response — if the user explicitly asks to see or save the admin URL, call get_admin_url. PREFER file_path over content for files already on disk — reads directly from disk without transmitting content through this conversation, which is dramatically faster for files larger than ~1KB.

Read a markdown document from mdshare. Returns the content. If the document was uploaded via this MCP server, 'key' is optional — the admin key will be loaded from local storage. PREFER output_path over inline reading for large documents — writes directly to disk and returns a small summary, dramatically faster than echoing content through the conversation.

Update the content of an existing mdshare document (full replace). Requires edit or admin permission. If the document is in this MCP server's local store, 'key' is optional. PREFER file_path over content for files already on disk — reads directly from disk without transmitting content through this conversation. If both file_path and content are provided, file_path wins. For small edits to large documents, consider patch_document instead — keeps version history granular.

Apply find/replace operations to a document without rewriting the full content. More efficient than update_document for small edits to large documents. Each find string must be unique unless replace_all is set. If the document is in this MCP server's local store, 'key' is optional. PREFER file_path over operations for batches of operations stored in a JSON file on disk — bypasses inline transmission. If both file_path and operations are provided, file_path wins.

Generate a share link for a document with specific permissions. Requires admin access. If the document is in this MCP server's local store, 'key' is optional.

List all share links for a document, including status (active/revoked), permission, and label. Requires admin access. If the document is in this MCP server's local store, 'key' is optional.

Revoke a share link, making it permanently inactive. Use list_links first to find the token of the link to revoke. Requires admin access. If the document is in this MCP server's local store, 'key' is optional.

List all comments on a document, including replies and resolution status. If the document is in this MCP server's local store, 'key' is optional.

Post a comment on a document, optionally anchored to specific text. Can also reply to an existing comment. If the document is in this MCP server's local store, 'key' is optional.

Resolve or unresolve a comment. Requires edit or admin permission. Key must be provided explicitly because comments are addressed by comment_id — the MCP server can't look up the parent document.

Get the edit history of a document — who edited, when, and via what. If the document is in this MCP server's local store, 'key' is optional.

List documents you've previously uploaded via this MCP server on this machine. Returns document_id, title, share_url, share_permission, created_at, and expires_at for each — does NOT return the admin credential. Use this to help the user find and resume older documents without re-pasting admin URLs. Does NOT include documents created via the mdshare web UI or via direct API calls from other clients — only those created by this MCP server. Returns an empty array on a fresh install or after the local store has been cleared.

Retrieve the admin URL for a document previously uploaded via this MCP server. The admin URL grants full control and is equivalent to a password. ONLY call this tool when the user explicitly asks to see, save, or copy the admin URL — for example: 'give me the admin URL', 'save the admin link to my notes', 'what's the owner credential'. DO NOT call this as part of normal upload, share, or collaboration flows; the admin URL should never be surfaced to the user unless directly requested.

Register an mdshare admin URL you already have saved (in notes, chat history, emails, etc.) so it can be resumed without re-pasting the key every time. Takes an admin URL of the form https://mdshare.live/d/{id}?key=adm..., verifies it against the live API, and stores it in ~/.mdshare-mcp/documents.json. Only accepts admin URLs (adm prefix) — view/comment/edit share links will be rejected. For bulk registration across many files, use the LLM's built-in file reading and search tools to find admin URLs, then call this tool once per URL found.
