The Accountability Layer
for AI Agents
MCP connects agents to tools.
TrustAgentAI makes those connections cryptographically provable.
Kirill Ostrovskii · kirbas@me.com
The Problem
AI agents are executing
high-stakes actions with zero accountability
When an agent calls execute_wire_transfer — nobody can prove what happened.
🔓
No non-repudiation
Agent owners can claim "I never authorized this $50K transfer." Logs are editable. Timestamps are unverified. Nobody can prove otherwise.
📋
No intent binding
There's no proof the final action matched the original intent. Agent drift or prompt injection can silently change what gets executed.
⚖️
No dispute-grade evidence
When things go wrong, there's nothing to show auditors, insurers, or courts. MCP has no concept of a legal evidence trail.
The Solution
A cryptographic receipt for
every MCP tool call
3-phase signed handshake. No changes to your agents or tools.
01 // INTENT
Intent Envelope
Agent A signs: intent, args hash, tool schema hash, TTL, nonce
→
02 // ACCEPT
Acceptance Receipt
Agent B signs: validation result, policy eval hash, risk budget
→
03 // EXECUTE
Execution Envelope
Agent B signs: outcome hash, timestamp, linked to intent
const result = await proxyA.forwardToolCall(mcpCall, executeTool);
Why TrustAgentAI
Not a gateway. Not a monitor.
A proof system.
