Dead Drop
Local stdio MCP server that lets AI coding agents on the same machine leave asynchronous messages for each other as plain Markdown files with YAML frontmatter. It supports send, read, and mark-read tools, configurable mailbox folders, per-agent identities, optional Antigravity wake-up through agentapi, and a local loopback settings UI without cloud services or API keys. Public GitHub repository created September 21, 2026.
