WHAT IT DOES

What custom_query_opportunity_roles does on Marketo MCP Server

AI agents invoke custom_query_opportunity_roles to trigger actions in Marketo MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why custom_query_opportunity_roles is rated High

The tool makes direct REST API calls to Marketo, which could include read or write operations depending on how it's invoked. The 'custom_query' prefix suggests data retrieval, but 'Calls the Marketo REST API directly' implies it could execute any HTTP method (GET, POST, PUT, DELETE). Given the ambiguity and potential for side effects, Execute is the most appropriate category.

From the tool's definition 'Calls the Marketo REST API directly' — executes arbitrary API calls against Marketo; 'custom_query' suggests querying but direct REST API access could have side effects beyond reads

RECOMMENDED RULE

The rule that runs custom_query_opportunity_roles safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Marketo MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For custom_query_opportunity_roles, this is the rule to start with:

custom_query_opportunity_roles Rate-limited

custom_query_opportunity_roles stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
