"Stack Exchange" matching MCP servers:

Enables AI agents to interact with an OVH Exchange mailbox via EWS and NTLM authentication, including searching, reading, sending, replying to, and forwarding emails, as well as managing folders and attachments.

A local MCP server for on-premises Microsoft Exchange, connecting via EWS and NTLM. It provides mail, template, availability, and calendar workflow tools through stdio, with draft-first safety and Windows Credential Manager integration.

Enables AI assistants to run real Exchange Management Shell tasks against on-premise Microsoft Exchange for administration, monitoring, and troubleshooting, including recipient provisioning, transport troubleshooting, and DAG/health monitoring.

A self-hosted server that connects AI assistants, including claude.ai as a custom connector, to an existing IMAP/SMTP or Microsoft Exchange mailbox. It enables searching and reading email, inspecting attachments in bounded chunks, and — when explicitly enabled for IMAP/SMTP — sending messages, managing drafts and organizing folders.

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

Enables AI chat sessions to exchange messages and structured data with each other, preserving provenance and conversation threads, so work in one chat can be reused in another without manual copying.

Enables Claude Code, Codex CLI and Antigravity (Gemini) agents to exchange messages that are pushed live into each other's open sessions, with mail_send, mail_check and mail_peers tools so no agent has to poll. Mail can also be bridged over SSH between machines with no shared filesystem.

Enables AI coding agents in different harnesses, projects, or machines to share encrypted peer-to-peer rooms and exchange messages directly, without any central server or account.

Enables communication with G1 Bluetooth devices using the Nordic UART protocol over BLE. Supports device discovery, connection management, and message exchange for G1 audio devices through natural language commands.

Relays a result screenshot to Slack so you can review a coding agent's output without opening the app.

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

MCP server that reads Slack through your own browser session, authenticating as you rather than a bot. Provides tools to search messages, retrieve channel/DM/thread history, resolve users, and post messages (write disabled by default).

The LinkedIn API and MCP server for AI agents: search, connect, message and enrich on accounts you own, with limits enforced on our server. 20,000+ LinkedIn accounts run on this stack, and under 1% of them have ever been restricted.

Enables reading Slack channels, messages, and threads using the web interface via a persistent browser session, designed for guest users without API access. Does not send messages.

A read-only MCP server for Slack that reads messages from channels the bot is invited to, without storing data. It provides tools to fetch channel history, thread replies, and resolve user IDs, with access controlled solely by channel invitations.

Enables searching and reading public Slack channels, and sending messages with two-step confirmation.

A self-hosted, read-only Slack MCP server that runs locally and provides read-only access to Slack channels, messages, and users via the Slack Web API, with no third-party intermediary.

Bridges Matrix chat rooms to CodeBuddy Code sessions, enabling message exchange, permission approvals, and media downloads through the MCP protocol.

MCP coordination primitive for multi-agent workflows. Lets multiple AI coding agents (Claude Code, Cursor, n8n, custom clients) discover each other and exchange messages and tasks via a shared SQLite-backed message bus.

MCP server that connects Claude Code to Slack, allowing two-way communication via Slack Socket Mode without tunnels.
