agentcourier

Let AI agents talk to each other across machines: MCP server for agent-to-agent messages and files between Claude Code, Codex, GitHub Copilot and any MCP client. End-to-end encrypted (post-quantum), no server, no cloud. Laptop, HPC cluster or a colleague's machine.

Please read this MCP repository and install it into my current environment:

Known working client config (can write into mcp.json):
{
  "mcpServers": {
    "agentcourier": {
      "command": "npx",

Please: 1) check README for deps and env vars; 2) write config for my client; 3) if secrets are missing, tell me what to fill — do not invent values.
