PhronEdge

Constitutional AI governance for every agent, every tool, every call.

pip install phronedge

What it does

PhronEdge wraps your AI agent tool calls with 7 governance checkpoints. Under 50ms. Your data stays in your runtime. Works with any framework.

from phronedge import PhronEdge

pe = PhronEdge(agent_id="fraud-analyst")

@pe.govern("claim_lookup", action="read", jurisdiction="DE")
def claim_lookup(claim_id: str) -> str:
    """Look up an insurance claim by ID."""
    return db.query(claim_id)

# This call passes through 7 checkpoints before executing
result = claim_lookup("CLM-2026-001")

Frameworks

Works with every major agent framework. One decorator. Same pattern.

Multi-agent

One API key. Multiple agents. Each with independent credentials, tools, and clearances.

pe_fraud = PhronEdge(agent_id="fraud-analyst")
pe_kyc = PhronEdge(agent_id="agt-kyc-orch-v1")
pe_settle = PhronEdge(agent_id="agt-settle-v1")

7 checkpoints

Every governed tool call passes through:

1. Credential validation : ECDSA P-256 signature verified
2. Tool permission : Is this tool in the signed credential?
3. Data classification : Does agent clearance match the data level?
4. PII detection : Input scanned for personal data
5. Jurisdiction check : Is this jurisdiction allowed for this tool?
6. Behavioral analysis : Is this call within normal baseline?
7. Output constraints : Response scanned before return

Enterprise

Deploy PhronEdge on your own infrastructure. Same SDK. Same @pe.govern(). One env var change.

# SaaS (default)
export PHRONEDGE_API_KEY=pe_live_xxx

# Enterprise (your k8s, your KMS, your Postgres)
export PHRONEDGE_API_KEY=pe_live_xxx
export PHRONEDGE_GATEWAY_URL=https://governance.internal.bank.com/api/v1

Per-tenant ECDSA P-256 signing keys. Independent verification via public key endpoint. Multi-cloud KMS (AWS, GCP, Azure). Storage abstraction (Firestore or Postgres). Helm chart for k8s. Docker, ECS, Cloud Run. Your developer's code doesn't change.

196 jurisdictions. 30 controls. SHA-256 hash-chained audit trail. Tamper-proof. Mathematically verifiable.
