UTA — the universal trust layer for ALL AI agents (not just one)

UTA — the universal trust layer for ALL AI agents

Every AI agent tool has the same problem: how do you trust an MCP server before loading it?

Tool	MCP support	Trust verification
Cline	✅	❌ None
Cursor	✅	❌ None
Continue.dev	✅	❌ None
Aider	✅	❌ None
OpenHands	✅	❌ None
LangChain	✅	❌ None
CrewAI	✅	❌ None

UTA fixes this for ALL of them. One package, universal compatibility.

What UTA provides

1. 8 credential format support — ATC v3, JWT, W3C VC, A2A, EAT-AI, ZTA, MCP Card, X.509
2. 12-stage fail-closed pipeline — UNKNOWN = DENY, ERROR = DENY, EXPIRED = DENY, REVOKED = DENY
3. Pre-exec filter — blocks .env reads, rm -rf, shell spawns, credential exfiltration
4. Merkle tree audit log — tamper-evident, signed
5. Behavioral drift detection — detects when MCP server behavior changes over time
6. Attack chain detection — catches multi-step attacks across tool calls
7. Memory poisoning detection — detects injected instructions in tool responses
8. Cross-agent trust — Agent A verifies Agent B before delegation
