List labels across the workspace or organisation, with optional search and scope filters. Returns ids, names, colors, status, and timestamps so you can choose a label_id before get_prompt_label or update_prompt_version.
AI agents call list_prompt_labels 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 |
|---|---|---|---|
search | string | — | Search labels by name |
page_size | number | — | Results per page (max 100) |
current_page | number | — | Page number for pagination |
workspace_id | string | — | Filter by workspace ID |
organisation_id | string | — | Filter by organisation ID |
Parameters from the server's own tool schema.
Even though list_prompt_labels 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 labels across the workspace or organisation, with optional search and scope filters. Returns ids, names, colors, status, and timestamps so you can choose a label_id before get_prompt_label or update_prompt_version. It is categorised as a Read tool in the Portkey Admin MCP Server, which means it retrieves data without modifying state.
list_prompt_labels accepts 5 parameters: search, page_size, current_page, workspace_id, organisation_id. 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_prompt_labels: 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_prompt_labels 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_prompt_labels 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_prompt_labels. 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_prompt_labels 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.
