hive-matrix-mcp

Per-agent matrix integration: a long-running daemon (hive-matrix-daemon) that holds a matrix-sdk Client + sync loop per configured account and serves the matrix tool surface (send_message, send_dm, list_rooms, read_room, …) directly over streamable-http. No stdio bridge, no per-turn respawn — claude reconnects to the same stable URL every turn.

When to use it

Look here when changing matrix tool behaviour, multi-account handling, or the incoming-event → todo/wake path. The daemon owns the whole lifecycle: per-account bring-up (accounts.rs, client.rs), the sync loop that sweeps invites/unread rooms into the harness's in-agent todo socket (timeline.rs, wake.rs), and the MCP tool router itself (mcp.rs).

Shape

One bin (hive-matrix-daemon, src/main.rs) built from the crate's own lib (src/lib.rs):

• accounts.rs — multi-account config + the account→Client dispatch registry (main is always the hive-internal primary; extras come from HIVE_MATRIX_ACCOUNTS).
• client.rs — session restore, stale-token recovery, avatar sync, cross-signing bootstrap.
• timeline.rs / wake.rs — per-sync-callback invite/unread sweeps that push todos onto HIVE_AGENT_SOCKET.
• handlers.rs — per-tool dispatch, returns protocol::DaemonResponse.
• mcp.rs — the rmcp tool router + serve_http, resolving each call's optional account arg against the registry before calling into handlers.
• paths.rs — per-agent path resolution (token file, matrix-sdk state dir, homeserver URL, accounts snapshot).
