MCP Tool Reference Medium Risk

create_directory

Create a new directory or ensure it exists

Part of the Filesystem MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

modelcontextprotocol/server-filesystem Write

WHEN AI AGENTS USE THIS TOOL

AI agents use create_directory to create or modify resources in Filesystem. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON CREATE_DIRECTORY

Without a policy, an AI agent could call create_directory repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Filesystem.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

FREQUENTLY ASKED QUESTIONS

What does the create_directory tool do?

Create a new directory or ensure it exists. It is categorised as a Write tool in the Filesystem MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_directory?

Add a rule in your Intercept YAML policy under the tools section for create_directory. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Filesystem MCP server.

What risk level is create_directory?

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

Can I rate-limit create_directory?

Yes. Add a rate_limit block to the create_directory rule in your Intercept 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 create_directory completely?

Set action: deny in the Intercept policy for create_directory. 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 create_directory?

create_directory is provided by the Filesystem MCP server (modelcontextprotocol/server-filesystem). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
