List available datasets (directories) in the DATASET_DIRECTORY.
AI agents call list_datasets 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 read-only operation to enumerate datasets in a directory. It retrieves information without modifying, creating, or deleting data. The blast radius is minimal—misuse would only reveal what datasets exist locally, with no capability to alter state or access external systems.
From the tool's definition Tool name 'list_datasets' and description 'List available datasets (directories)' indicate a query operation that retrieves directory listings with no side effects.
Attacks that exploit this kind of access
List available datasets (directories) in the 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_datasets: 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_datasets 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_datasets 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_datasets. 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_datasets 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.
