Claude Can Use Your Computer Now. Here's How to Make It Verify Trust First.

Anthropic shipped Computer Use. Claude can open apps, browse the web, call APIs, and run tools on your Mac. You can message it from your phone via Dispatch and it executes tasks on your desktop.

But when your Claude agent calls another agent's API during a Computer Use session, how does it know that agent is trustworthy?

The Problem

A Claude Desktop agent calling an external API trusts it implicitly. No verification, no trust score, no audit trail. This is fine for code autocomplete. Not fine when making API calls with real data on your behalf.

The Solution: MCP Trust Tools

AgentStamp provides 17 MCP tools that let any Claude agent verify trust before interacting with external services. All free, no API key needed.

Verify Before You Trust

Before sending data to an external service, Claude calls trust_check and gets a trust score (0-100), tier, stamp status, and delegation count. If below your threshold, it refuses to proceed.

Present Your Own Identity

Claude calls get_verifiable_credential and gets a W3C VC Data Model 2.0 credential, interoperable with any VC verifier. The agent equivalent of showing your ID.

Compliance Check Before Delegation

Claude calls compliance_report to get EU AI Act risk level, human sponsor info, audit trail integrity, and trust status before delegating tasks.

The Audit Trail

Every interaction through AgentStamp MCP tools is logged in a SHA-256 hash-chained audit trail. Tamper-evident, exportable as JSON, independently verifiable.

Why This Matters Now

Computer Use turns Claude into a full desktop agent. Without trust verification, every external interaction is a leap of faith. The agents that survive won't be the ones that do the most — they'll be the ones that can prove they should be trusted.
