"How to allow an LLM to ask questions to a user" matching MCP servers:

Enables saving files and folders to a local NAS over NFS with automatic share discovery, smart mounting, and seamless file transfers.

A local agent that monitors your system clipboard, automatically uploads copied images to Supabase Storage, and replaces the clipboard content with the public URL for immediate sharing.

An MCP server that gives an AI agent controlled access to a Selectel cloud account: OpenStack cloud servers, S3 object storage, and account billing.

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 LLM agents to lift local files into Google Drive as native Docs, Sheets, or Slides with formatting preserved, by passing file paths directly without routing bytes through the conversation.

MCP server for EveryPage that lets an AI assistant turn a PDF into a tracked share link and report who read it, how far they got, and where they stopped.

Read-only access to a local Hiberden backup catalog: list projects, archives, tapes, and jobs, check 3-2-1 coverage, and verify a stored copy by reading it back and re-hashing it. Runs against the catalog on your own machine, so nothing leaves it.

Upload any file from the local filesystem and get a shareable, expiring link — with tools to check file status, list recent uploads, and delete files on demand.

Enables MCP clients to connect to AWS S3 buckets, list, upload, and read objects in various formats, supporting public and private buckets with multiple transport modes.

Enables MCP-compatible AI assistants to manage iDrive backup/restore operations, including listing devices, browsing and downloading backed-up files, and performing mutations like creating folders, deleting files, or restoring from trash.

An MCP server that exposes Backblaze B2 Cloud Storage as tools any MCP-compatible AI client can call. Manage B2 by talking to an assistant -- list buckets, upload, download, delete versions, and check usage against a budget.

A read-only MCP server for Gmail and Drive with only 5 tools, designed to be friendly to small local LLMs by minimizing context usage and simplifying inputs.

Enables AI assistants to explore and manage S3-compatible object storage (AWS S3, RustFS, MinIO, Cloudflare R2) by listing buckets and objects, inspecting metadata, and reading object contents with capped range requests. Write operations such as upload and delete are available but disabled unless explicitly enabled, with optional bucket allow-listing and custom TLS trust.

Enables an AI assistant to connect to multiple Google accounts at once, searching and acting across Gmail, Drive, Calendar, and Contacts from a single interface.

Exposes Poi's external APIs (file upload/download, commenting, license key issuance) as MCP tools for use with LLM clients like Claude.

An MCP server that wraps the rustypaste API, allowing users to upload text, files, and URLs to a rustypaste instance. It supports features such as single-use links, file expiration, and URL shortening.

A local MCP server giving Claude access to Trimble Connect, with 40 tools for projects, folder trees, files, versions, members, groups, and permissions via the Core API v2.

Enables Claude Code to manage Gmail, Google Calendar, and Google Drive via a dedicated Google account, keeping personal data separate.

Enables exporting data from databases to files (CSV, TSV, JSON, BSON, Parquet, XLSX, Binary) with optional cloud storage targets, via a two-step preview-execute safety process.

Enables file uploads to AWS S3 buckets with automatic MIME type detection.
