WHAT IT DOES

What renew_tls_certificate does on 20i MCP Server

AI agents use renew_tls_certificate to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.

RISK

Why renew_tls_certificate is rated Medium

Renewing a TLS/SSL certificate modifies/updates an existing certificate, which is a reversible write operation. It doesn't delete data or execute arbitrary code. Misuse could cause service disruption if applied incorrectly, but it's fundamentally a write/update action.

RECOMMENDED RULE

The rule that runs renew_tls_certificate safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 20i MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For renew_tls_certificate, this is the rule to start with:

renew_tls_certificate Rate-limited

renew_tls_certificate 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.
