Use a fmsg address for a fmsg host. Tools for inbox, threads, send and reply, reactions, attachments, delivery status and wait-for-message over the host's WebSocket so agents can hold conversations with people or other agents. Runs over stdio locally or as a Streamable HTTP endpoint where each user authenticates with their own fmsg API key.
Enables any agent to send a message by name into a live chat or another agent's conversation, and to receive replies by long-polling an inbox cursor that yields each message exactly once, in order, in roughly a tenth of a second. Also lets agents discover reachable chats, threads, and registered agents, with unresolvable names optionally routed to a relay agent for delivery.
Provides a mail-like coordination layer for coding agents, enabling them to register identities, exchange messages through inbox/outbox, search threaded history, and declare advisory file reservations to prevent conflicts.
Enables two coding agents on separate machines to communicate directly via a private git repo, with end-to-end encryption and no server required. Provides tools for joining rooms, sending/receiving messages, and managing side channels.
Enables AI coding agents to communicate and coordinate through a durable, vendor-neutral message bus with support for threads, tasks, presence, and webhooks.
