WHAT IT DOES

What update_files does on Wpm Mcp Server

AI agents use update_files to create or update resources in Wpm Mcp Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Wpm Mcp Server environment.

RISK

Why update_files is rated Medium

The tool modifies file metadata, which is a Write operation—data is created or changed but reversibly. The severity is medium because unintended metadata updates could affect file organization, access controls, or integrity, but the operation is not destructive (files themselves are not deleted) and the server context includes financial operations (refunds, payments, charges) suggesting this may be a backend service…

From the tool's definition Tool name is 'update_files' and description states 'Updates a metadata of the file.' This is a modification operation that changes file metadata reversibly.

RECOMMENDED RULE

The rule that runs update_files safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Wpm Mcp Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_files, this is the rule to start with:

update_files Rate-limited

update_files stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
