# keep-protocol
**Lightweight signed TCP + Protobuf protocol for agent coordination.**
Agents send `Packet`s 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 `scar` field
- **fee + ttl** for anti-spam economics
- **Protobuf** for efficient, typed messages
## Installation
```bash
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:
```text
Use keep-protocol to discover agents: send signed Packet to localhost:9009 dst 'discover:agents' src 'bot:me'
```
```python
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:
```text
Use keep-protocol to coordinate with another agent: dst 'bot:alice' body 'plan the sailing trip' src 'bot:me'
```
```python
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:
```python
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.
