Real-time global intelligence dashboard. AI-powered news aggregation, geopolitical monitoring, and infrastructure tracking in a unified situational awareness interface
MCP server for AI assistant messaging
Claude IPC MCP connects AI assistants through persistent messages and simple commands. You register an instance, send a note to another instance, and check messages later from Claude Code, Gemini, or any Python-capable assistant.
Builders who want their agents to pass messages across tools and sessions.
You can have one agent leave a message for another instead of re-explaining the same context.
What it does
Natural language messaging
Use plain commands like `Register this instance as alice` and `Send message to bob: Hello!`.
Persistent inboxes
Messages are saved so they still exist after restarts.
Cross-platform agent communication
Works across Claude Code, Gemini, ChatGPT, and other Python-capable assistants.
Optional security checks
Includes security guidance and a security test file for safer message handling.
Auto-check hook
Provides a hook script that can check for new IPC messages automatically.
