"file system" 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.

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 AI agents to directly control Android devices via Termux, providing 120+ tools for screen manipulation, file management, app control, and system operations with layered loading and security gating.

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.

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.

Enables MCP hosts to bridge with QQ via NapCat/OneBot 11, allowing whitelisted private messages to reach an agent with full tool access while group mentions are answered by a sandboxed pure LLM without system access.

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.

An MCP server that connects Claude to a 3CX Phone System (V20+), enabling user management, call monitoring, contact search, and forwarding configuration.

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.

A server that enables users to chat with each other by repurposing the Model Context Protocol (MCP), designed for AI tool calls, into a human-to-human communication system.

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.
