keep-protocol

Lightweight signed TCP + Protobuf protocol for agent coordination.

Agents send Packets to a TCP endpoint (default localhost:9009). Unsigned or invalid sig = silent drop. Valid ed25519 sig = routed, logged, replied.

Preferred: MCP Tools (Fast Path)

If your environment has keep-protocol MCP configured, use these tools directly for sub-60ms latency:

Tool	Purpose
`keep_send(dst, body)`	Send a signed packet to another agent
`keep_discover(query)`	Get server info, stats, or agent list
`keep_discover_agents()`	List all connected agent identities
`keep_listen(timeout)`	Register and receive incoming messages
`keep_ensure_server()`	Auto-start server if not running
