WHAT IT DOES

What store-routing-credentials does on Rendezvous

AI agents use store-routing-credentials to create or update resources in Rendezvous, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rendezvous environment.

RISK

Why store-routing-credentials is rated Medium

This tool stores sensitive cryptographic payment credentials (macaroon + preimage) derived from a Lightning Network L402 payment flow. The act of storing these credentials is a Write operation (creating/persisting data). However, because it involves payment-related credentials (preimage proves payment, macaroon grants access post-payment), it sits at the boundary of Financial and Write.

RECOMMENDED RULE

The rule that runs store-routing-credentials safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Rendezvous, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For store-routing-credentials, this is the rule to start with:

store-routing-credentials Rate-limited

store-routing-credentials stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
