[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP).
AI agents call custom_browse_landing_pages 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 data from Marketo. The 'browse' operation implies listing or viewing existing landing pages without creating, modifying, deleting, or executing any changes. Even though it makes direct API calls, those calls are for data retrieval only. No destructive, financial, or code execution risks are evident.
From the tool's definition Tool name 'custom_browse_landing_pages' and description indicating it 'Calls the Marketo REST API directly' to browse/retrieve landing pages.

Register the Marketo MCP Server MCP server in PolicyLayer and add a rule for custom_browse_landing_pages: 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_browse_landing_pages 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_browse_landing_pages 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_browse_landing_pages. 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_browse_landing_pages 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.
