Get all versions of a file.
AI agents call get_file_versions to retrieve information from NGS360 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 historical version metadata for a file without modifying, deleting, or executing any operations. It is a straightforward data retrieval function consistent with Read category tools like 'get' and 'fetch'. There is minimal risk of misuse—returning version history cannot harm data integrity or trigger unintended external effects.
From the tool's definition Tool name 'get_file_versions' combined with description 'Get all versions of a file' indicates a retrieval operation with no side effects. The verb 'get' and the read-only nature of retrieving version history confirm this is a query operation.
Attacks that exploit this kind of access
Get all versions of a file. It is categorised as a Read tool in the NGS360 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the NGS360 MCP Server MCP server in PolicyLayer and add a rule for get_file_versions: 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 NGS360 MCP Server. Nothing to install.
get_file_versions 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_versions 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_versions. 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_versions is provided by the NGS360 MCP Server MCP server (ngs360/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
