Get one packaged parameter workflow by id or alias.
AI agents call get_parameter_workflow to retrieve information from JS Reverse MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries a packaged workflow by identifier. The use of 'Get' and the retrieval semantics ('by id or alias') indicate a read-only operation with no side effects, data modification, code execution, or destructive capabilities. It falls squarely into the Read category with low severity, as misuse would only expose existing workflow data without enabling unauthorized changes or external operations.
From the tool's definition Tool name 'get_parameter_workflow' with verb 'Get' and description 'Get one packaged parameter workflow by id or alias' indicates a retrieval operation that queries and returns data without modification.
Attacks that exploit this kind of access
Get one packaged parameter workflow by id or alias. It is categorised as a Read tool in the JS Reverse MCP MCP Server, which means it retrieves data without modifying state.
Register the JS Reverse MCP server in PolicyLayer and add a rule for get_parameter_workflow: 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 JS Reverse MCP. Nothing to install.
get_parameter_workflow 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 get_parameter_workflow 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 get_parameter_workflow. 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.
get_parameter_workflow is provided by the JS Reverse MCP server (noone-hub/jsreverser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
