VerifyLink Infrastructure

Cryptographic accountability for every AI decision.

When an AI agent acts on your data, signs a contract, makes a recommendation, or accesses a record — VLI seals what it did, why, and with what context. Every action becomes a tamper-evident receipt your auditors, regulators, and customers can verify forever.

An AI agent's decision being sealed and registered as a tamper-evident receipt

The gap

Three problems VLI solves.

What organizations have today vs. what they'll have tomorrow once every AI action is sealed.

Gap The accountability gap Today: "the model recommended approval."
Tomorrow: a sealed record showing which model, what version, what data it saw, what reasoning steps, signed at the moment of decision.
Gap The audit-trail gap Today: opaque LLM calls in your logs.
Tomorrow: every agent session begins with ai_begin_session, every decision sealed, every data access registered. Auditable end-to-end.
Gap The governance gap Today: AI policy lives in PDFs no one reads.
Tomorrow: policy is enforced in the seal — a decision either has its required attestations or it doesn't. The math doesn't bend.

Why now

Why this matters now.

Regulators are asking organizations to prove AI systems behaved correctly — EU AI Act, NIST AI RMF, sector-specific rules in healthcare and finance. The proof has to be portable, tamper-evident, and verifiable without trusting the AI vendor.

VLI is that proof layer. It doesn't try to govern what your AI does. It makes what your AI did impossible to deny later.

AI Trust MCP

Six tools. Drop into Claude Code or any agent.

Cryptographic accountability turns on the moment they're registered.

Tool ai_begin_session Start a sealed agent session with an attested identity.
Tool ai_seal_decision Record an agent decision, inputs, reasoning, outputs.
Tool ai_seal_access Record what data the agent read or wrote.
Tool ai_checkpoint Anchor session state at intervals so partial work is provable.
Tool ai_end_session Close and seal the session bundle.
Tool ai_verify Verify a sealed AI session matches its registered Merkle proof.

Session bundle

What a sealed AI session looks like.

This bundle works in any ClearKey CLI install. No VLI dependency at verification time.

Install

Install + configure

First, mint an AI Trust API key from the Vault developer console — it'll become your VLI_API_KEY. Then add to your Claude Code MCP config:

{
  "mcpServers": {
    "ai-trust": {
      "command": "node",
      "args": ["./mcp-ai-trust/src/server.js"],
      "env": {
        "VLI_API_KEY":      "vli_ai_...",   // from /vav/#keys
        "VLI_REGISTRY_URL": "https://verifylinkinfra.com/registry-api",
        "VLI_ART_API":      "https://vliart.com/api",
        "VLI_AGENT_ID":     "your-agent-identity"
      }
    }
  }
}

Public registry

Looking for the public registry of AI agents?

ART (AI Registry & Trust) is the public-facing companion — a transparency log of AI agents, what they're authorized to do, who delegated that authority, and the trust attestations behind them. Every sealed session via the AI Trust MCP can anchor to ART.

Audience

Who this is for.

Builder AI engineers building agent systems Provable agent behavior, no extra database, no logging hacks. Drop in the MCP and turn it on.
GRC Compliance & risk officers Audit-ready AI by default. Every decision a tamper-evident receipt. Frameworks: EU AI Act, NIST AI RMF, HIPAA AI use, FINRA.
Research AI safety researchers Independent verifiability of agent behavior. ClearKey + the AI Trust MCP = a research substrate that doesn't require trusting the lab.
