Manages .ai/ workspace folder, syncs assets with a cloud service, and generates environment-specific bootstrap files for AI context management.

Enables secure one-time encrypted file and note sharing by encrypting data locally before upload and providing tools for sending, listing, checking, and revoking links.

Enables editing existing Docs, Sheets, and Slides in place, plus commenting, sharing, moving, and exporting files with native Google URLs returned. Provides 29 tools across Drive, Docs, Sheets, and Slides, using OAuth keys kept locally in ~/.gdrive-mcp/.

Enables AI agents to open, read, and edit Word and Excel documents through a local bridge, create Word files in existing SharePoint folders, and work with document content via an Office add-in.

Enables ChatGPT to list, search, and read files from a user's Google Drive—including Docs, Sheets, Slides, and text files—through read-only Google OAuth access.

This server enables multi-agent conversations that interact with the Google Drive API, allowing agents to perform file operations, manage permissions, and handle Google Drive content through a standardized protocol.

Enables Google Drive, Sheets, and Docs operations; ATS job-board reads and liveness checks; local notes and HTTP connectors through MCP.

A Model Context Protocol server that provides seamless access to multiple storage services including S3, Azure Blob Storage, and Google Cloud Storage through Apache OpenDAL™.

Provides a standardized way to interact with MinIO object storage, allowing access to text files, binary files, and bucket contents while supporting operations like listing buckets/objects, retrieving objects, and uploading files.

Enables ChatGPT users to search and browse a private photo library, inspect metadata, and receive real image previews through read-only tools, while keeping encrypted sessions server-side.

Enables MCP-compliant agents such as Antigravity to create, read, update, and search Google Drive files and Google Docs, Sheets, Slides, and Forms through OAuth-authenticated tools.

Enables Claude to search, read, create, and edit a user's personal WPS cloud documents, spreadsheets, and presentations—including reading and writing cells, replacing text, and discovering and running any of 619 WPS capabilities, with explicit confirmation required for destructive or sensitive operations. It runs remotely with one-time OAuth authorization, so no local install is needed.

Enables Antigravity IDE to directly interact with Google Docs, Sheets, Drive, Gmail, and Calendar, with token-optimized operations to reduce context usage by 70-90%.

Enables AI agents to send emails and manage tasks in Microsoft To Do with scoped, low-risk access to Microsoft Graph.

A second brain in one cloud-drive folder that your AI agent reads, writes and keeps tidy.

Lets AI assistants share HTML they generate as a private, end-to-end encrypted link, and update the page later at the same link. The page is encrypted locally before upload, the key stays in the link, and no account is needed.

Lets a coding agent upload files from disk to a Stickafile portal and return a shareable link, with the bytes going straight from disk to storage without entering the model's context. Also lists the portals a token can push to.

Enables AI clients to search a cloud-drive resource search engine and turn selected results into saveable share links, using a two-step search-then-retrieve workflow.

Enables AI tools to publish HTML pages and get shareable URLs instantly, with optional account features for persistence, in-place updates, and visibility control.
