A local MCP server enabling multiple Claude Code and Claude Desktop conversations to exchange messages through a shared SQLite file, with a UI for moderating rooms.

MCP server that watches issue trackers and comments for 'Dear Claude' and spawns local Claude Code instances to execute tasks, posting results back to the original platform.

Enables multiple Claude Code sessions to join the same named room and exchange messages so they can sync context without manual copy-pasting. Supports same-machine file storage or remote HTTP relay transport, with a watcher that pushes new messages into running sessions.

Enables Claude Code instances to discover each other and exchange messages instantly via a local broker and channel protocol. Supports scoped peer discovery, reliable ack-based delivery, and cross-platform operation.

Enables AI agents to access user and message data through MCP resources, providing REST API integration for user management with paginated lists and thread tracking.

Enables two people's Claude agents to hold a live conversation about the same project, using GitHub Issues as channels and Issue comments as messages. Each side can list channels, open new ones, send and read messages, and wait for the other's reply, while both users follow and join in directly on GitHub.

Enables real-time communication between Claude Code instances across multiple machines via WebSocket, allowing context sharing, task handoffs, and coordination between sessions.

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.

This server enables Claude Code to send notifications and ask questions via Telegram, allowing user interaction during coding tasks.

A Gmail MCP server that enables Claude to send, search, and read emails using either Gmail API or SMTP/IMAP backend.

Sends Telegram alerts for Claude Code status updates, including notifications for task completion, user requests, and custom status updates with normal or urgent priority.

It runs entirely on your machine over Slack Socket Mode—no tunnel or public IP—routes misdelivered messages to the right project, and masks credentials in anything it posts back.

Enables bidirectional communication between AI coding assistants and Telegram, allowing interactive confirmations via inline buttons, media and screenshot ingestion, and on-demand message polling without a background daemon.

Enables users to interact with their live Claude Code session from Google Chat by injecting messages and receiving replies, bridging terminal and mobile conversations.
