What aviation.accidents does on Mcp
AI agents call aviation.accidents to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why aviation.accidents is rated Low
This is a pure data retrieval tool that queries a public historical database. The action is read-only with no side effects—it cannot modify data, execute commands, or trigger external operations. The presence of filter parameters does not elevate it beyond Read category, as these merely scope the query results. Low severity due to read-only nature and public data source.
From the tool's definition Tool performs a search/query of NTSB historical accident database with filtering options. Returns events with metadata (date, location, aircraft, injury counts, report URL). No creation, modification, deletion, or execution of external operations.

The rule that runs aviation.accidents safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For aviation.accidents, this is the rule to start with:
aviation.accidents is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every aviation.accidents call is checked against it from then on.
