List all shared files with metadata (passwords excluded).
AI agents call list_shared_files to retrieve information from Overlord MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a listing/query operation to retrieve file metadata from a shared repository. While it accesses shared files (which could be sensitive), it is read-only and explicitly excludes passwords. The 'medium' severity reflects that an agent could enumerate and identify shared resources for reconnaissance or exfiltration, but cannot modify or destroy data.
From the tool's definition Tool name is 'list_shared_files' and description states 'List all shared files with metadata (passwords excluded)' — a retrieval operation with no modification or deletion capability.
Attacks that exploit this kind of access
List all shared files with metadata (passwords excluded). It is categorised as a Read tool in the Overlord MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Overlord MCP Server MCP server in PolicyLayer and add a rule for list_shared_files: 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 Overlord MCP Server. Nothing to install.
list_shared_files 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 list_shared_files 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 list_shared_files. 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.
list_shared_files is provided by the Overlord MCP Server MCP server (skeeminator/overlord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
