Lets a human review what an AI agent is about to post to a chat tool (Slack first) before it is sent. Renders the draft, destination and warnings (@here/@channel, unresolved mentions, format issues) in a neutral local HTML preview; never sends anything.

An MCP-based email tool that enables AI models to access email services through standardized interfaces, allowing AI assistants to perform various email operations like sending emails, reading inboxes, and handling attachments.

A Model Context Protocol tool that enables Claude to interact with Microsoft Outlook for macOS, allowing users to read/send emails, manage calendar events, and access contacts through natural language commands.

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 interaction with the Twitch API, allowing users to retrieve comprehensive information about channels, streams, games, and more, with additional support for searching and accessing chat elements like emotes and badges.

Enables an AI assistant to browse a signed-in school-communication account's classes, chats and message streams, inspect and adjust notification preferences and delivery devices, and send messages to a chat or class. Write actions require explicit user confirmation, and a read-only GraphQL tool allows arbitrary queries for anything the built-in tools don't cover.

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.

Enables AI coding tools to search and read a user's Mattermost channels and DMs using their own account, allowing AI to answer questions about team conversations with read-only access.
