update_prompt_label · Portkey Admin MCP: Risk & Policy

WHAT IT DOES

What update_prompt_label does on Portkey Admin

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

PARAMETERS

Parameter	Type	Required	Description
`name`	string	—	New name for the label
`label_id`	string	Yes	Label ID to update
`color_code`	string	—	New hex color code (e.g., '#FF5733')
`description`	string	—	New description

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why update_prompt_label needs a policy

An AI agent can call update_prompt_label faster than any human can review — one bad instruction and it creates or modifies resources in Portkey Admin by the hundred, each call as confident as the last.

Verdict

update_prompt_label Rate-limited

update_prompt_label 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.

FAQ

Questions about update_prompt_label

What does the update_prompt_label tool do? +

Update a prompt label's name, description, or color only, unlike update_prompt_version which changes which label a version carries. This takes effect immediately for all versions already tagged with the label, but does not reassign labels or touch history; use list_prompt_labels to find the label_id first. It is categorised as a Write tool in the Portkey Admin MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does update_prompt_label accept? +

update_prompt_label accepts 4 parameters: name, label_id, color_code, description. Required: label_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on update_prompt_label? +

Register the Portkey Admin MCP server in PolicyLayer and add a rule for update_prompt_label: 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.

What risk level is update_prompt_label? +

update_prompt_label is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit update_prompt_label? +

Yes. Add a rate_limit block to the update_prompt_label 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.

How do I block update_prompt_label completely? +

Set action: deny in the PolicyLayer policy for update_prompt_label. 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.

What MCP server provides update_prompt_label? +

update_prompt_label 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.
