Return metadata fields for the official DOL OSHA inspection or violation dataset.
AI agents call osha_fields to retrieve information from DOL WHD MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves structural information about a dataset without modifying, executing operations on, or deleting data. It is a simple metadata query typical of data exploration tools. Severity is low because misuse poses minimal risk—an agent could only discover what fields exist in public government datasets, with no ability to harm data or systems.
From the tool's definition Tool returns metadata fields from a dataset ('Return metadata fields for the official DOL OSHA inspection or violation dataset'). This is a retrieval operation with no side effects—it queries schema/field information only.
Attacks that exploit this kind of access
Return metadata fields for the official DOL OSHA inspection or violation dataset. It is categorised as a Read tool in the DOL WHD MCP MCP Server, which means it retrieves data without modifying state.
Register the DOL WHD MCP server in PolicyLayer and add a rule for osha_fields: 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 DOL WHD MCP. Nothing to install.
osha_fields 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 osha_fields 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 osha_fields. 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.
osha_fields is provided by the DOL WHD MCP server (uhq-actual/dol_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
