Returns the list of directories that this server is allowed to access.
AI agents call list_allowed_directories to retrieve information from Server Sequential Thinking without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to list accessible directories. It retrieves data about server permissions without side effects, no data modification, no execution of arbitrary code, and no destructive operations. The blast radius of misuse is minimal—an adversary learns only which directories the server can access, which is already constrained by the server's own permissions model.
From the tool's definition Tool name 'list_allowed_directories' and description 'Returns the list of directories that this server is allowed to access' indicate a query operation that retrieves configuration/permission information without modifying state or executing external…
Attacks that exploit this kind of access
Returns the list of directories that this server is allowed to access. It is categorised as a Read tool in the Server Sequential Thinking MCP Server, which means it retrieves data without modifying state.
Register the Server Sequential Thinking MCP server in PolicyLayer and add a rule for list_allowed_directories: 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 Server Sequential Thinking. Nothing to install.
list_allowed_directories 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_allowed_directories 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_allowed_directories. 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_allowed_directories is provided by the Server Sequential Thinking MCP server (@modelcontextprotocol/server-sequential-thinking). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
