WHAT IT DOES

What create_release does on Ncp

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

RISK

Why create_release is rated Medium

This tool creates a new release entity in Sentry, which is a reversible write operation. It modifies the Sentry system state by adding a new release record but does not delete data, execute arbitrary code, move money, or have irreversible consequences. The blast radius is moderate—a mistaken release creation could cause confusion or require cleanup, but the operation itself is correctable.

From the tool's definition Tool name is 'create_release' and description states 'Create Sentry release', indicating it creates a new release object in Sentry.

RECOMMENDED RULE

The rule that runs create_release safely

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

create_release Rate-limited

create_release 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every create_release call is checked against it from then on.
