WHAT IT DOES

What vault_container_escrow_create does on 0nmcp

AI agents use vault_container_escrow_create to create or update resources in 0nmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 0nmcp environment.

RISK

Why vault_container_escrow_create is rated Medium

This tool creates cryptographic keypairs and establishes an escrow arrangement for multi-party vault access. Creating keypairs and escrow configurations is a Write operation (generates new data/credentials). The severity is high because misuse could compromise vault access control — generating escrow keypairs for unauthorized parties could grant them access to sensitive vault contents.

From the tool's definition Generate escrow keypairs for multi-party vault access. Creates X25519 keypairs for each party.

RECOMMENDED RULE

The rule that runs vault_container_escrow_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 0nmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For vault_container_escrow_create, this is the rule to start with:

vault_container_escrow_create Rate-limited

vault_container_escrow_create 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.
