WHAT IT DOES

What import_grades does on Moodle

AI agents use import_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
`file`	string	Yes	An absolute local path to the CSV
`items`	object	—	Column header → grade item id
`mapTo`	string	Yes
`mapFrom`	string	Yes	The column (its header) that identifies each person
`preview`	boolean	—	Only show how Moodle reads the file
`courseId`	integer	Yes
`encoding`	string	—	One Moodle offers; UTF-8 by default
`feedback`	object	—	Column header → the grade item whose feedback it is
`separator`	string	—

Parameters from the server's own tool schema.

RISK

Why import_grades is rated Medium

An AI agent can call import_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 import_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 import_grades, this is the rule to start with:

import_grades Rate-limited

import_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 import_grades call is checked against it from then on.

FAQ

Questions about import_grades

What does the import_grades tool do? +

Import grades into a course's gradebook from a local CSV file, as Moodle's CSV import does: mapFrom is the column that identifies each person and mapTo what it holds (user id, username, ID number or email); items says which grade item (an id from get_gradebook_setup) each other column goes into, feedback which item's feedback. preview: true only shows how Moodle reads the file, importing nothing: do that first. Moodle imports all or nothing. The file identifies people: only with names in clear (the server's student data level). Changes grades students see: confirm with the person first. 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 import_grades accept? +

import_grades accepts 9 parameters: file, items, mapTo, mapFrom, preview, courseId, encoding, feedback, separator. Required: file, mapTo, mapFrom, courseId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on import_grades? +

Register the Moodle MCP server in PolicyLayer and add a rule for import_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 import_grades? +

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

Can I rate-limit import_grades? +

Yes. Add a rate_limit block to the import_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 import_grades completely? +

Set action: deny in the PolicyLayer policy for import_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 import_grades? +

import_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.
