Retrieve detailed metadata about a file or directory. Returns comprehensive
AI agents call get_file_info to retrieve information from Filesystem MCP Server (HTTP Streaming) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file/directory metadata with no side effects. It is a read-only operation that queries information about existing files. Despite the filesystem server's broader capabilities (write, move, delete operations available as sibling tools), this specific tool performs only data retrieval, classifying it as Read with low severity.
From the tool's definition Tool name is 'get_file_info' and description states 'Retrieve detailed metadata about a file or directory. Returns comprehensive' — retrieval of metadata without modification.
Attacks that exploit this kind of access
Retrieve detailed metadata about a file or directory. Returns comprehensive. It is categorised as a Read tool in the Filesystem MCP Server (HTTP Streaming) MCP Server, which means it retrieves data without modifying state.
Register the Filesystem MCP Server (HTTP Streaming) MCP server in PolicyLayer and add a rule for get_file_info: 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 Filesystem MCP Server (HTTP Streaming). Nothing to install.
get_file_info 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_file_info 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_file_info. 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_file_info is provided by the Filesystem MCP Server (HTTP Streaming) MCP server (jeswin/mcpfs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_file_info is one line of Filesystem MCP Server (HTTP Streaming)'s registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
