[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP).
AI agents call custom_get_activity_export_file to retrieve information from Marketo 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 and exports activity data from Marketo, which is fundamentally a read operation. While the blast radius is medium because exported activity data could include sensitive lead and engagement information that might be misused if exfiltrated, the tool itself performs no side effects, modifications, or irreversible actions.
From the tool's definition Tool name includes 'get' and 'export' indicating data retrieval. Description states it 'Calls the Marketo REST API directly' for activity export operations. Activity exports are read-only operations that retrieve historical data without modifying state.
Attacks that exploit this kind of access
[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP). It is categorised as a Read tool in the Marketo MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Marketo MCP Server MCP server in PolicyLayer and add a rule for custom_get_activity_export_file: 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 Marketo MCP Server. Nothing to install.
custom_get_activity_export_file 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 custom_get_activity_export_file 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 custom_get_activity_export_file. 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.
custom_get_activity_export_file is provided by the Marketo MCP Server MCP server (tyron-pretorius/marketo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
