Find duplicate files by comparing MD5 hashes. Returns groups of identical files.
AI agents call find_duplicates to retrieve information from Local Files MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
find_duplicates performs a read-only operation that scans files, computes hashes, and reports results without altering any data. This is a data retrieval and analysis operation with no side effects, fitting the Read category. Severity is low because misuse would only expose information about duplicate files, not cause data loss or unintended modification.
From the tool's definition Tool description states it 'Find[s] duplicate files by comparing MD5 hashes' and 'Returns groups of identical files.' No modification, deletion, or execution occurs; the tool only queries and compares file metadata.
Attacks that exploit this kind of access
Find duplicate files by comparing MD5 hashes. Returns groups of identical files. It is categorised as a Read tool in the Local Files MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Local Files MCP Server MCP server in PolicyLayer and add a rule for find_duplicates: 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 Local Files MCP Server. Nothing to install.
find_duplicates 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 find_duplicates 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 find_duplicates. 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.
find_duplicates is provided by the Local Files MCP Server MCP server (tobiasarg/localfilesorganizer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
