WHAT IT DOES

What update_token does on Marketo MCP Server

AI agents use update_token to create or update resources in Marketo MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Marketo MCP Server environment.

RISK

Why update_token is rated Medium

The tool modifies existing Marketo tokens reversibly. While tokens can affect program execution and email rendering, the action itself is a standard update operation without permanent deletion. This is classified as Write rather than Execute because it modifies configuration data rather than triggering campaign execution.

From the tool's definition Tool name 'update_token' with description 'Update an existing token in Marketo' indicates modification of existing data. Tokens in Marketo are used in email templates and programs to personalize content and control program behavior.

RECOMMENDED RULE

The rule that runs update_token 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 update_token, this is the rule to start with:

update_token Rate-limited

update_token stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
