"Understanding File Usage" matching MCP servers:

Enables uploading local files to Slack with a message, supporting channels, DMs, threads, and file titles.

Enables local AI agents to prepare, send, and check the status of user-specified files to a preconfigured QQ recipient through SnowLuma, using checksum-verified copies and persistent delivery records.

MCP server with persistent memory, voice understanding, multi-thread orchestration, and remote control via Telegram for AI assistants.

Enables a Telegram bot to securely deliver local files to the owner's private chat and lets the owner approve in-chat plugin updates.

Enables Codex to locate QQ groups by name or number and search group file directories and recent chat attachments by filename, then download selected files through a locally deployed NapCat instance, returning paths, sizes, and SHA-256 hashes.

A Model Context Protocol server providing file search and question tools for AI models. Enables keyword search in files with line numbers and integration with external chat services.

Enables LLMs to send DM messages to a human via Discord webhook when they need attention — a question, blocker, decision, or completed work — using a standardized, user-controlled format read from a local file or hosted URL.

Enables AI agents to control and monitor QQ accounts through the NapCatQQ OneBot 11 protocol, covering private/group messaging, forwards, group administration, file transfer, OCR, friend and profile management, and real-time message listening. It also handles QR-code login, hot-switching between multiple QQ accounts, and one-click self-check, deployment, and updates.

Enables AI assistants to send native LinkedIn voice notes by uploading audio, validating sends with dry runs, delivering to LinkedIn contacts, and checking delivery status and usage.

Give your agent an address: private agent-to-agent messaging, free encrypted file handoffs, and Lightning commerce. Buy, sell, and discover files, data, APIs, and compute on a public marketplace. Non-custodial: buyers pay sellers directly and payment unlocks delivery.

Connects Claude Code instances to a clawborrator hub via WebSocket, enabling cross-session communication, file exchange, and agent dispatch.

Enables peer-to-peer asynchronous conversation between Claude.ai and Claude Code instances via a shared file-based notebook, allowing them to leave messages, start threads, and organize by project.

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

Local agent-to-agent messaging and coordination for coding sessions on one machine, through MCP and a CLI. Includes threaded mail, full-text search, per-repository agent rosters, advisory file reservations, and optional notifications. Integrations cover Claude Code, Codex, Cursor, Devin, Grok, OpenCode, and Antigravity. Standalone agents and T3 Code sessions can share the same local server.

Enables MCP-capable agents to read your own Discord direct messages and group DMs through the official Discord web client in a dedicated Chrome browser, with read-only access and no token or API usage.

Lets separate coding-agent sessions coordinate through a shared, role-addressed mailbox instead of a human relaying every message, over a single local SQLite file or a hosted server with many isolated channels. Messages can be sent as tracked obligations that stay open until one side resolves and the other confirms, alongside threads, full-text search, work statuses, and an append-only versioned pin system where protected changes require recorded agreement from every declared role.

MCP server for inter-agent mailbox communication using file-based mailboxes in .claude directories.

Lets MCP clients sign a member in through LinkedIn's three-legged OAuth flow, read that member's OpenID profile, and publish text posts on their behalf, with stored sessions kept in a local mode-0600 file. It uses only public member APIs, so messaging, invitations, media uploads, and other people's data stay out of scope.

Security-first SendGrid MCP server: two-phase sends, dry-run by default, recipient allowlists, rate limits, audit log, no BCC. One auditable file.

Automatically transcribes Google Chat voice messages using Groq Whisper API, and also supports local audio file transcription.

Enables concurrent terminal sessions or other MCP clients on the same machine to register, exchange messages, check inboxes/replies, and coordinate tasks through file-based storage without a daemon or network port.

An MCP server and CLI for Ed Discussion that gives LLMs access to threads, comments, attendance, moderation, file uploads, and instant local search through 43 tools.

Enables Genesys Cloud queue administration and conversation analytics, including queue search/creation, conversation sampling, voice quality, sentiment, topics, transcripts, and OAuth client usage.

Generate professional AI-powered presentations from a topic, raw text, or document file. Export to PPTX, PDF, image, or shareable link.

eSIM data plans for 200+ countries: search wholesale plans, check balance and usage, diagnose eSIM connectivity from live network data, and (opt-in) order and top up eSIMs with a confirmation step.

Enables programmatic access to Austrian mobile carriers (yesss!, Georg, XOXO) account management. Allows users to check usage, download bills, manage SIM settings, and configure call forwarding through natural language interactions.

Enables multiple AI agents and humans working in the same project to share status, exchange messages, and claim files through a local collaboration board. It supports project-specific enablement, conflict-aware file claims, and shared state via SQLite.

Exposes the Telegram Bot API as tools for Claude Code or any MCP client, enabling message sending, chat management, file handling, and bot information retrieval.

Enables agents and applications to send notifications through configurable channels such as Telegram or a JSONL file, with queued delivery, status tracking, idempotency, and event-based routing.

Exposes Windows WeChat desktop client automation as MCP tools, letting AI agents check connection status, list chats, read buffered messages, and send text or files to explicitly specified contacts or groups. Includes safety controls such as target disambiguation, file directory whitelists, optional send confirmation, and operation auditing.
