WHAT IT DOES

What update_secret_reference does on Portkey Admin

AI agents use update_secret_reference 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.

RISK

Why update_secret_reference is rated Medium

This is a Write operation because it modifies secret reference configuration in a reversible manner (auth_config can be updated again, workspace mappings can be replaced). However, severity is high rather than medium due to the explicit warning about credential exposure to transcripts and the sensitive nature of secret reference management.

From the tool's definition Tool description states it 'Update[s]' secret reference fields, which is a modification operation. The description explicitly warns that 'Credential values are sent to Portkey and exposed to the MCP transcript,' indicating sensitive data handling.

RECOMMENDED RULE

The rule that runs update_secret_reference safely

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

update_secret_reference Rate-limited

update_secret_reference 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.

What does the update_secret_reference tool do? +

How do I enforce a policy on update_secret_reference? +

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

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

Can I rate-limit update_secret_reference? +

How do I block update_secret_reference completely? +

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