What list_conversations does on Moodle
AI agents call list_conversations to retrieve information from Moodle without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | How many conversations (20 by default, up to 100) |
offset | integer | — | How many conversations to skip first, latest first (0 by default) |
Parameters from the server's own tool schema.
Why list_conversations is rated Low
Even though list_conversations only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs list_conversations 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 list_conversations, this is the rule to start with:
list_conversations is read-only, so it stays allowed. 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 list_conversations call is checked against it from then on.
Questions about list_conversations
List the person's message conversations, latest first: private, group or with themselves, their members (aliases when the server pseudonymizes), unread count and the last message as text. A page at a time: limit conversations (20 by default) after skipping offset; more says whether there are others. Read one with get_conversation. It is categorised as a Read tool in the Moodle MCP Server, which means it retrieves data without modifying state.
list_conversations accepts 2 parameters: limit, offset. The full parameter table on this page comes from the server's own tool schema.
Register the Moodle MCP server in PolicyLayer and add a rule for list_conversations: 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.
list_conversations 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 list_conversations 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 list_conversations. 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.
list_conversations 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.
