List dataset sources, versions, and last-updated timestamps.
AI agents call data_sources to retrieve information from EMC Regulations MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries metadata about data sources without creating, modifying, executing, or deleting anything. It is a pure Read operation with minimal security risk—an AI agent cannot misuse it to cause harm, only to understand what data is available.
From the tool's definition Tool name 'data_sources' and description 'List dataset sources, versions, and last-updated timestamps' indicate retrieval of metadata about available datasets.
Attacks that exploit this kind of access
List dataset sources, versions, and last-updated timestamps. It is categorised as a Read tool in the EMC Regulations MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EMC Regulations MCP Server MCP server in PolicyLayer and add a rule for data_sources: 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 EMC Regulations MCP Server. Nothing to install.
data_sources 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 data_sources 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 data_sources. 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.
data_sources is provided by the EMC Regulations MCP Server MCP server (rfingadam/mcp-emc-regulations). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
