openagentmesh 0.1.0

Python SDK for agent-to-agent communication based on the Open Agent Mesh Protocol

OpenAgentMesh

Connect agents like you'd call an API

OpenAgentMesh is the fabric for multi-agent systems. It makes coding complex interaction patterns as simple as writing REST endpoints.

It's an SDK with batteries included:

• Request/reply, pub/sub, and event streaming
• Typed contracts with self-discovery
• Shared KV and Object stores

No hardcoded interactions, full decoupling.

Quickstart

1. Start the mesh:

oam mesh up

2. Register an agent (agent.py):

from pydantic import BaseModel
from openagentmesh import AgentMesh, AgentSpec

mesh = AgentMesh()

class EchoInput(BaseModel):
    message: str

class EchoOutput(BaseModel):
    reply: str

@mesh.agent(AgentSpec(name="echo", description="Echoes a message back."))
async def echo(req: EchoInput) -> EchoOutput:
    return EchoOutput(reply=f"Echo: {req.message}")

mesh.run()

python agent.py

3. Discover and call it from the terminal:

oam mesh catalog
oam agent contract echo
oam agent call echo '{"message": "hello"}'

No hardcoded addresses. The CLI discovers echo from the mesh, reads its contract, and calls it.
