WHAT IT DOES

What export_grades does on Moodle

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

Parameter	Type	Required	Description
`format`	string	Yes
`destDir`	string	Yes	An absolute local folder
`display`	array	—
`groupId`	integer	—
`itemIds`	array	—	Only these grade items
`courseId`	integer	Yes
`feedback`	boolean	—	Include feedback

Parameters from the server's own tool schema.

RISK

Why export_grades is rated Medium

An AI agent can call export_grades faster than any human can review: one bad instruction and it creates or modifies resources in Moodle by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs export_grades safely

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

export_grades Rate-limited

export_grades 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.

}

The button opens the PolicyLayer dashboard: create your workspace, connect Moodle, apply this rule, and every export_grades call is checked against it from then on.

FAQ

Questions about export_grades

What does the export_grades tool do? +

Save a course's grades into a local folder as Moodle exports them for a teacher: a spreadsheet (xlsx, ods), CSV or XML, with the items, group, display and feedback chosen. The file names every participant: only with names in clear (the server's student data level), since a file can't be pseudonymized. It is categorised as a Write tool in the Moodle MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does export_grades accept? +

export_grades accepts 7 parameters: format, destDir, display, groupId, itemIds, courseId, feedback. Required: format, destDir, courseId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on export_grades? +

Register the Moodle MCP server in PolicyLayer and add a rule for export_grades: 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 Moodle. Nothing to install.

What risk level is export_grades? +

export_grades is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit export_grades? +

Yes. Add a rate_limit block to the export_grades 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.

How do I block export_grades completely? +

Set action: deny in the PolicyLayer policy for export_grades. 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.

What MCP server provides export_grades? +

export_grades is provided by the Moodle MCP server (@falkenslab/moodle-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
