What create_server_response does on Postman
AI agents use create_server_response to create or update resources in Postman, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Postman environment.
Why create_server_response is rated Medium
This tool creates new resources (server responses) in Postman, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. While it modifies Postman state, the blast radius is limited to API mock/testing infrastructure rather than production systems.
From the tool's definition Tool is named 'create_server_response' and description states it 'Create[s] a server response'. The verb 'create' indicates data creation/modification.
Attacks that exploit this kind of access
The rule that runs create_server_response safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Postman, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_server_response, this is the rule to start with:
create_server_response 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Postman, apply this rule, and every create_server_response call is checked against it from then on.

Register the Postman MCP server in PolicyLayer and add a rule for create_server_response: 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 Postman. Nothing to install.
create_server_response is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_server_response 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 create_server_response. 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.
