agentrust-py 0.0.1a1

AgentTrust Edge — the AI Agent Harness. One decorator, full trust enforcement.

agentrust-py

Python SDK for AgentTrust Edge — runtime AI agent governance with zero-config startup and env-only rollback.

---

Install

pip install "agentrust-py[embedded,retry]"

---

30-second quickstart

from agentrust_sdk import harness, embed_gateway

# Optional: start an in-process SQLite gateway (dev / air-gap)
embed_gateway()

@harness
def my_agent(user: str, input: str) -> dict:
    """Decorated agent. Governance happens automatically after each call."""
    return {"answer": "42"}

result = my_agent(user="alice", input="What is the meaning of life?")
print(result)   # {"answer": "42"} — or BlockedError if policy rejects it

Note on imports: The PyPI package name is agentrust-py; the Python module is agentrust_sdk. All imports use from agentrust_sdk import ....

---

Rollback (no code change, no image rebuild)

export AGENTRUST_ENABLED=false
# restart process — @harness becomes a no-op identity wrapper

---

Configuration

Every tunable is an env var — no config file required for basic usage.

Variable	Default	Purpose
AGENTRUST_ENABLED	true	Master kill-switch
AGENTRUST_GATEWAY_URL	http://localhost:8000	Gateway URL
AGENTRUST_FAILURE_MODE	open	open | closed | queue
AGENTRUST_TIMEOUT_SEC	10	Request timeout
AGENTRUST_RETRY_ATTEMPTS	3	Retries (needs [retry])
AGENTRUST_KEY	—	API key

---

Deployment ladder (env-only)

# Dev — embedded SQLite, no external services
AGENTRUST_ENABLED=true
# (call embed_gateway() at startup)

# Staging — remote gateway, fail safe
AGENTRUST_GATEWAY_URL=https://agentrust-staging.internal:8000
AGENTRUST_KEY=at_...
AGENTRUST_FAILURE_MODE=closed

# Production
AGENTRUST_GATEWAY_URL=https://agentrust.internal:8000
AGENTRUST_FAILURE_MODE=open
AGENTRUST_RETRY_ATTEMPTS=5

App code is identical across all three environments.

---

Failure modes

Mode	Gateway unreachable behaviour
open (default)	Log warning, return approve response — agent continues
closed	Raise GatewayUnavailableError — agent is blocked
queue	Write request to local SQLite buffer; return approve response

Queue mode note: The local buffer is written but not automatically replayed in the current release. Use agentrust export to inspect buffered records. A background drain/replay worker is on the roadmap.

---

Extras

Extra	Installs
embedded	uvicorn, fastapi — in-process gateway via embed_gateway()
retry	tenacity — exponential backoff
otel	opentelemetry-sdk, opentelemetry-api — traces + metrics
langgraph	LangGraph AgentTrustNode adapter
crewai	CrewAI AgentTrustCallback adapter
full	All of the above

---

Tiers

Tier	Capabilities
