Agentmesh - AI agent governance middleware
Governance middleware for AI agents: deterministic policy enforcement, cryptographic audit trails with digital signatures, DLP/PII detection, Trust Score per agent (0-100), EU AI Act compliance (Art. 9, 11, 12, 14), Agent BOM generation, and Circuit Breaker. Native support for LangGraph, CrewAI, and AutoGen.
Overview
AgentMesh
Scan your AI agents for governance gaps. Enforce policies in production.
What is AgentMesh?
AgentMesh is a governance platform for AI agents, built in two layers:
- Scan CLI (free, offline, no account) — Analyzes your codebase via AST to find governance gaps, generate an Agent BOM, and map EU AI Act requirements. Like
snyk testfor AI agents. - Runtime Platform (SaaS, requires account) — Middleware that intercepts tool calls in production to enforce policies, scan payloads for PII, and track agent trust. Like
snyk monitorfor AI agents.
Quick Start
pip install useagentmesh
agentmesh scan .
# → Governance Score: 35/100 | 8 findings | Agent BOM: 3 agents, 12 tools
# → Run `agentmesh auth login` to enable runtime governance

"AGENTMESH_API_KEY": "your-api-key"
}
}
}
}

Benchmark Results
All measurements taken with time.perf_counter_ns(), 10,000 iterations after 1,000 warmup. Methodology & reproduction →
Policy Engine (33 deterministic rules, zero LLMs):
| Scenario | P50 | P99 |
|---|---|---|
| Single rule evaluation | 0.031ms | 0.08ms |
| Full scan (33 rules) | 1.84ms | 3.2ms |
| Batch (100 tool calls) | 1.79ms | 2.8ms |
Governance overhead is <0.2% of a typical LLM call (~800ms).
AST Framework Discovery:
| Framework | Avg Latency |
|---|---|
| CrewAI | ~5ms |
| LangGraph | ~7ms |
| AutoGen | ~9ms |
Runtime Governance (SaaS Platform)
When you connect the SDK to the AgentMesh platform, you unlock runtime governance features that protect your agents in production:
- 🔐 DLP Runtime — Presidio-based PII/PCI scanning on tool call payloads before they hit downstream APIs
- 📊 Dynamic Trust Score — 0-100 EigenTrust score per agent, updated on every interaction
- ⚡ Circuit Breaker — Auto-suspends agents when Trust Score drops below threshold
- 🔐 Cryptographic Audit Trail — SHA-256 hash chain + Ed25519 digital signatures (non-repudiation)
- 👥 RBAC + Teams — Multi-user access control per organization
- 📋 EU AI Act Reports — Exportable compliance reports for regulators
The Most Advanced Agent Controls
- 🧭 Operational Design Domain (ODD) — Define permitted tools, rate limits, and cost caps per agent. Enforcement modes: audit, enforce, escalate
- 📏 Pre-Action Magnitude Limits — Pre-trade risk controls for AI agents: financial spend caps, data volume limits, blast radius constraints, and compute guardrails — validated before every action executes
- 🤖 Agent Identity Management — Managed credential lifecycle for non-human identities: DID provisioning, auto-rotation with grace periods, instant revocation, and ephemeral JWT support
