List video files in a directory within DATASET_DIRECTORY.
AI agents call list_videos to retrieve information from Synphony MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query/browse operation on the local filesystem to enumerate video files. It retrieves data without creating, modifying, deleting, or executing any operations. The action is read-only and has minimal blast radius if misused—worst case would be information disclosure about directory contents.
From the tool's definition Tool name 'list_videos' and description 'List video files in a directory' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List video files in a directory within DATASET_DIRECTORY. It is categorised as a Read tool in the Synphony MCP MCP Server, which means it retrieves data without modifying state.
Register the Synphony MCP server in PolicyLayer and add a rule for list_videos: 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 Synphony MCP. Nothing to install.
list_videos 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_videos 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_videos. 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_videos is provided by the Synphony MCP server (rukasuamarike/synphony-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
