[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP).
AI agents call custom_get_landing_page_domains 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 or queries landing page domain information from Marketo without creating, modifying, or deleting data. The 'get' verb and domain query context confirm a read-only operation. While the description is minimal, the naming convention and context (sibling tools include approve, activate, create which are more permissive) suggest this is a simple data retrieval endpoint.
From the tool's definition Tool name 'custom_get_landing_page_domains' with 'get' and 'domains' indicates retrieval of landing page domain data.
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_landing_page_domains: 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_landing_page_domains 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_landing_page_domains 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_landing_page_domains. 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_landing_page_domains 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.
