Installation

pip install policymesh

Quick Start

from policymesh import PolicyMeshClient

# Initialize with your org ID and API key
# Get your API key at https://policymesh.vercel.app → API Keys
client = PolicyMeshClient(
    org_id="your_org_id",
    api_key="your_api_key"
)

# Evaluate an agent action
decision = client.evaluate(
    agent_id="my_agent",
    action_type="data_export",
    data_classification="confidential",
    record_count=1500,
    description="Exporting customer records to external email"
)

print(decision.decision)       # "block"
print(decision.policy_matched) # "Sensitive Data Export Block"
print(decision.is_blocked)     # True

Using the Guard Decorator

from policymesh import PolicyMeshClient

client = PolicyMeshClient(
    org_id="your_org_id",
    api_key="your_api_key"
)

@client.guard(action_type="production_deploy", environment="production")
def deploy_to_production():
    print("Deploying to production...")

deploy_to_production()

Simple Boolean Check

if client.allow(agent_id="my_agent", action_type="data_access"):
    pass

Handling Decisions

from policymesh import PolicyMeshClient, PolicyBlockedError, PolicyEscalateError

client = PolicyMeshClient(
    org_id="your_org_id",
    api_key="your_api_key"
)

try:
    decision = client.evaluate(
        agent_id="my_agent",
        action_type="production_deploy",
        environment="production"
    )
    if decision.is_flagged:
        print("Action flagged but allowed.")
except PolicyBlockedError as e:
    print(f"Action blocked: {e.policy_matched}")
except PolicyEscalateError as e:
    print(f"Action requires approval: {e.policy_matched}")
