WHAT IT DOES

What sandbox_credentials_grant does on Appaloft

AI agents invoke sandbox_credentials_grant to trigger actions in Appaloft. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Parameter	Type	Required
`grantId`	string	Yes
`sandboxId`	string	Yes
`secretRef`	string	Yes
`destination`	string	Yes
`parameterName`	string	—
`transformation`	string	Yes

Parameters from the server's own tool schema.

RISK

Why sandbox_credentials_grant is rated High

sandbox_credentials_grant triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

RECOMMENDED RULE

The rule that runs sandbox_credentials_grant safely

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

sandbox_credentials_grant Rate-limited

sandbox_credentials_grant stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

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