register_provider · Tenzro Ledger MCP: Risk & Policy

WHAT IT DOES

What register_provider does on Tenzro Ledger MCP

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

WHY IT NEEDS A POLICY

Why register_provider needs a policy

Registering a provider creates/modifies persistent network state by adding a new provider entry and associating it with a service endpoint. While this could impact network operations, it is reversible (provider can be deregistered), making it Write rather than Execute or Destructive.

From the tool's definition Tool name 'register_provider' and description 'Register as a network provider with a service endpoint' indicate creation of a new provider record with associated endpoint configuration. This is a reversible data modification operation.
