List provider API keys stored as virtual keys in your Portkey org. Use this to find slugs before wiring prompts/configs or auditing limits. Returns total plus name, slug, status, usage limits, rate limits, reset state, and model config.
AI agents call list_virtual_keys to retrieve information from Portkey Admin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
page_size | number | — | Number of results per page (max 100) |
current_page | number | — | Page number for pagination |
Parameters from the server's own tool schema.
Even though list_virtual_keys 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
List provider API keys stored as virtual keys in your Portkey org. Use this to find slugs before wiring prompts/configs or auditing limits. Returns total plus name, slug, status, usage limits, rate limits, reset state, and model config. It is categorised as a Read tool in the Portkey Admin MCP Server, which means it retrieves data without modifying state.
list_virtual_keys accepts 2 parameters: page_size, current_page. The full parameter table on this page comes from the server's own tool schema.
Register the Portkey Admin MCP server in PolicyLayer and add a rule for list_virtual_keys: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Portkey Admin. Nothing to install.
list_virtual_keys is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_virtual_keys rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_virtual_keys. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_virtual_keys is provided by the Portkey Admin MCP server (CodesWhat/portkey-admin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
