Postal
Facilitates communication between multiple agents by providing a SQLite-backed message queue for asynchronous message exchange.
概要
Postal offers a robust mailbox system designed to enable seamless communication between two or more autonomous agents using the MCP protocol. It establishes a SQLite-backed message queue where all messages are stored, and the MCP server operates in HTTP-only mode, ensuring a shared database and queue across all communicating agents. This architecture simplifies agent interaction, allowing agents to send messages to designated recipients and check their own mailboxes, with the 'check_mailbox()' function blocking until a new message arrives.
