modbender keep-protocol
Lightweight signed TCP + Protobuf protocol for agent coordination.
Agents send Packets to a TCP endpoint (default localhost:9009 or relay).
Unsigned or invalid sig = silent drop. Valid ed25519 sig = routed, logged, replied.
Key Features
- ed25519 authentication + integrity on every packet
- Agent discovery — find who's online:
dst="discover:agents" - Agent-to-agent routing — send directly:
dst="bot:alice" - Memory barter — share knowledge via the
scarfield - fee + ttl for anti-spam economics
- Protobuf for efficient, typed messages
Installation
docker run -d -p 9009:9009 ghcr.io/clcrawford-dev/keep-server:latest
Python SDK: pip install keep-protocol
Discovery
Find out what's running and who's connected:
Use keep-protocol to discover agents: send signed Packet to localhost:9009 dst 'discover:agents' src 'bot:me'
from keep import KeepClient
client = KeepClient("localhost", 9009)
info = client.discover("info") # {"version": "0.3.0", "agents_online": 3, ...}
agents = client.discover_agents() # ["bot:alice", "bot:weather", ...]
Agent-to-Agent Routing
Send messages directly to other connected agents:
Use keep-protocol to coordinate with another agent: dst 'bot:alice' body 'plan the sailing trip' src 'bot:me'
with KeepClient(src="bot:planner") as client:
client.send(body="register", dst="server", wait_reply=True)
client.send(body="coordinate task", dst="bot:weather-agent")
client.listen(lambda p: print(f"From {p.src}: {p.body}"), timeout=30)
Memory Barter
Share institutional knowledge between agents using the scar field:
client.send(
body="trade weather data for flight cache",
dst="bot:travel-agent",
scar=b"<gitmem commit bytes>"
)
MCP Integration
Wrap keep-protocol as MCP tools for AI agent platforms.
See examples/mcp_keep_adapter.py for tool definitions.
