@nia-agent-cyber/agent-trust-mcp

MCP server that exposes Agent Trust SDK attestation tools to Claude Desktop and any MCP-compatible agent runtime.

Install

npm install -g @nia-agent-cyber/agent-trust-mcp

Claude Desktop Setup

Add this to your claude_desktop_config.json (usually at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "agent-trust": {
      "command": "agent-trust-mcp",
      "env": {
        "AGENT_TRUST_PRIVATE_KEY": "optional - only needed for issuing attestations"
      }
    }
  }
}

Restart Claude Desktop after saving. You should see the three tools available in the tool picker.

Tools

agent_trust_check

Get the trust tier and score for an agent Ethereum address. Returns tier level (0–4), tier name, score (0–100), and attestation count. Read-only — no private key required.

Inputs: address (required), network (base | base-sepolia, default: base)

agent_trust_issue

Issue an on-chain trust attestation for another agent. Requires AGENT_TRUST_PRIVATE_KEY to be set in the environment. Supports three attestation types:

• PaymentReliable — record a payment interaction (amount, currency, outcome)
• TaskCompletion — record a task completion (taskId, category, outcome, reward)
• SecurityAudit — record a security audit result (auditType, passed, severity)

Inputs: type (required), subjectAgent (required), plus type-specific fields, network

agent_trust_query

Fetch the full attestation history for an agent address. Returns PaymentReliable, TaskCompletion, and/or SecurityAudit attestation arrays along with a summary count. Read-only — no private key required.

Inputs: address (required), type (PaymentReliable | TaskCompletion | SecurityAudit | all, default: all), network

Example Usage

Once connected in Claude Desktop, you can ask:

"Check the trust score for agent 0xabc...123 on Base"

"What attestations does 0xdef...456 have? Show me their task completion history."

"Issue a PaymentReliable attestation for 0xghi...789 — they paid 1.5 ETH on time."
