AI agents call get_allowed_paths to retrieve information from Simple MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about allowed directory paths—a query operation with no side effects. It does not create, modify, delete, or execute anything; it simply returns read-only configuration data. The low severity reflects minimal blast radius if misused by an AI agent, as it only reveals which directories are accessible within the server's security sandbox.
From the tool's definition Tool name 'get_allowed_paths' and description 'アクセス可能なパスの一覧を表示します' (displays a list of accessible paths) indicate retrieval of configuration/metadata without modification.
Attacks that exploit this kind of access
アクセス可能なパスの一覧を表示します. It is categorised as a Read tool in the Simple MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Simple MCP Server MCP server in PolicyLayer and add a rule for get_allowed_paths: 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 Simple MCP Server. Nothing to install.
get_allowed_paths 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 get_allowed_paths 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 get_allowed_paths. 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.
get_allowed_paths is provided by the Simple MCP Server MCP server (p-united/mcpsample). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
