Get a workflow variable by ID.
AI agents call get_variable to retrieve information from Qontinui Web MCP Server 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 workflow variable data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that poses minimal security risk as it only accesses existing configuration data.
From the tool's definition The tool is named 'get_variable' and its description states 'Get a workflow variable by ID.' The verb 'get' and the read-only nature of retrieving a variable by identifier indicates a pure data retrieval operation with no side effects.
Attacks that exploit this kind of access
Get a workflow variable by ID. It is categorised as a Read tool in the Qontinui Web MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qontinui Web MCP Server MCP server in PolicyLayer and add a rule for get_variable: 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 Qontinui Web MCP Server. Nothing to install.
get_variable 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_variable 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_variable. 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_variable is provided by the Qontinui Web MCP Server MCP server (qontinui/qontinui-web-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
