moltrust_register · MolTrust MCP Server MCP: Risk & Policy

WHAT IT DOES

What moltrust_register does on MolTrust MCP Server

AI agents use moltrust_register to create or update resources in MolTrust MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MolTrust MCP Server environment.

WHY IT NEEDS A POLICY

Why moltrust_register needs a policy

Registration typically creates or modifies identity records reversibly. Given the trust/DID/credential context, this likely creates a new agent identity or enrollment record rather than reading or executing arbitrary operations. Without a description, confidence is moderate. Categorized as Write rather than Execute because registration is a standard data-creation operation, not dynamic code execution.

From the tool's definition Tool name 'moltrust_register' suggests registration or enrollment in a trust infrastructure system; parent server context involves DIDs (Decentralized Identifiers), verifiable credentials, and USDC, implying identity or account creation.
