agent_mcp_governance 3.5.0

Public Preview — MCP governance primitives for the Agent Governance Toolkit.

agent-mcp-governance

Public Preview — Standalone Python package that exposes the Agent Governance Toolkit's MCP (Model Context Protocol) governance primitives for use outside the full AGT monorepo.

Overview

agent_mcp_governance provides a thin, typed re-export surface over the governance, audit, and trust modules in agent-os-kernel. It is not zero-dependency — it requires agent-os-kernel >=3.0.0,<4.0.0.

Installation

pip install agent-mcp-governance

This will pull in agent-os-kernel automatically.

Quick Start

from agent_mcp_governance import (
    GovernanceMiddleware,
    AuditMiddleware,
    TrustGate,
    BehaviorMonitor,
)

# 1. Governance — block prompt-injection patterns
gov = GovernanceMiddleware(
    blocked_patterns=[r"(?i)ignore previous instructions"],
    allowed_tools=["web-search", "read-file"],
    rate_limit_per_minute=60,
)

# 2. Audit — tamper-evident hash-chain logging
audit = AuditMiddleware(capture_data=True)

# 3. Trust — DID-based agent identity verification
gate = TrustGate(min_trust_score=500)

# 4. Monitoring — detect rogue agents
monitor = BehaviorMonitor(
    burst_threshold=100,
    consecutive_failure_threshold=20,
)
