What credentials_show does on Appaloft
AI agents call credentials_show to retrieve information from Appaloft without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
credentialId | string | Yes | |
includeUsage | object | — |
Parameters from the server's own tool schema.
Why credentials_show is rated Low
Even though credentials_show only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs credentials_show 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 credentials_show, this is the rule to start with:
credentials_show is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Appaloft, apply this rule, and every credentials_show call is checked against it from then on.
