What list_folders does on AirMCP
AI agents call list_folders to retrieve information from AirMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_folders is rated Low
This is a read-only query that enumerates folder structures and provides metadata (note counts). It has no side effects, does not modify data, and does not execute code or trigger external operations. The blast radius of misuse is minimal — an agent would only gain visibility into folder organization and note counts, which is informational only.
From the tool's definition Tool name 'list_folders' and description 'List all folders across all accounts with note counts' — performs a retrieval operation with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
The rule that runs list_folders safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AirMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_folders, this is the rule to start with:
list_folders 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 AirMCP, apply this rule, and every list_folders call is checked against it from then on.
Questions about list_folders
List all folders across all accounts with note counts. It is categorised as a Read tool in the AirMCP MCP Server, which means it retrieves data without modifying state.
Register the Air MCP server in PolicyLayer and add a rule for list_folders: 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 AirMCP. Nothing to install.
list_folders 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_folders 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_folders. 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_folders is provided by the Air MCP server (airmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
