MSHA mine safety accident records via DOL Open Data Portal (~738k). Every US coal + metal/nonmetal mine accident since 2000. Filter by mine id, contractor id, FIPS state code, subunit (underground/surface/mill), accident date range, classification code.
AI agents call gov.msha-accidents to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical accident records from a public government data portal. It is a read/query operation with no side effects. The filters described are all query parameters. Severity is low because misuse only exposes public safety data, though note the server uses pay-per-call billing in USDC — the financial aspect is the server's billing model, not the tool's function itself.
From the tool's definition MSHA mine safety accident records via DOL Open Data Portal (~738k). Filter by mine id, contractor id, FIPS state code, subunit, accident date range, classification code.

MSHA mine safety accident records via DOL Open Data Portal (~738k). Every US coal + metal/nonmetal mine accident since 2000. Filter by mine id, contractor id, FIPS state code, subunit (underground/surface/mill), accident date range, classification code. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for gov.msha-accidents: 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 Mcp. Nothing to install.
gov.msha-accidents 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 gov.msha-accidents 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 gov.msha-accidents. 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.
gov.msha-accidents is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
