$pip install citizenofthecloud-agentframework

Early access — clone from GitHub for the latest version. PyPI package coming soon.

Quick Start

Add identity to your Agent Framework agents

Drop Cloud Identity tools and middleware into any Agent Framework agent. Verify participants, enforce trust policies across multi-agent workflows, and sign outbound requests.

Add Identity ToolsPython
from autogen_agentchat.agents import AssistantAgent
from citizenofthecloud_agentframework import cloud_identity_tools

# Get all identity tools
tools = cloud_identity_tools()

agent = AssistantAgent(
    name="security_agent",
    model_client=model_client,
    tools=tools,
    system_message="Verify agents before sharing data.",
)

Add Identity MiddlewarePython
from citizenofthecloud_agentframework import (
    CloudIdentityMiddleware,
    CloudIdentityFnMiddleware,
)

# AgentMiddleware — intercepts all agent messages
agent_mw = CloudIdentityMiddleware(
    minimum_trust=0.6,
    require_covenant=True,
)

# FunctionMiddleware — wraps tool calls with verification
fn_mw = CloudIdentityFnMiddleware(
    allowed_autonomy=["agent", "self-directing"],
)

agent = AssistantAgent(
    name="guarded_agent",
    model_client=model_client,
    agent_middlewares=[agent_mw],
    function_middlewares=[fn_mw],
)

Multi-Agent WorkflowPython
from citizenofthecloud_agentframework import verified_workflow

# Define a workflow where every participant is verified
@verified_workflow(minimum_trust=0.7)
async def research_pipeline(agents, query):
    # All agents verified before workflow starts
    researcher, analyst, writer = agents

    data = await researcher.run(query)
    analysis = await analyst.run(data)
    report = await writer.run(analysis)
    return report

Tools Reference

Identity tools and middleware

Tools work as standard Agent Framework function tools. Middleware intercepts agent messages and tool calls for automatic identity enforcement.

Tools

verify_cloud_agent

Verify an agent’s identity using Cloud ID, timestamp, and Ed25519 signature

lookup_cloud_agent

Look up an agent’s public profile and passport from the registry

check_agent_trust

Check an agent’s trust score against an optional minimum threshold

cloud_identity_tools()

Returns all three tools as a list for easy agent setup

Middleware

CloudIdentityMiddleware

AgentMiddleware — intercepts messages and verifies sender identity before delivery

CloudIdentityFnMiddleware

FunctionMiddleware — wraps tool calls with identity verification and trust checks

HTTP Client

CloudIdentityHTTPClient

Auto-signs outbound HTTP requests with X-Cloud-* headers

Configuration

Environment variables

Set these environment variables to enable request signing and middleware. Verification tools work without credentials.

Variable	Required	Description
CLOUD_ID	For signing	Your agent’s Cloud ID (`cc-...`). Required for signing outbound requests.
CLOUD_PRIVATE_KEY	For signing	Ed25519 private key in PEM format. Required alongside CLOUD_ID.
