Analyze a SQL query
AI agents call explain_query to retrieve information from ThinAir Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs analysis only (EXPLAIN-like functionality in SQL databases), which retrieves metadata and execution plans without modifying data or triggering side effects. It is a read-only diagnostic tool, posing minimal risk even if invoked by an AI agent with arbitrary input, as it cannot alter state or execute arbitrary queries.
From the tool's definition Tool name is 'explain_query' and description states 'Analyze a SQL query' — it reads and examines query structure/performance without executing writes, deletes, or external operations.
Attacks that exploit this kind of access
Analyze a SQL query. It is categorised as a Read tool in the ThinAir Data MCP Server, which means it retrieves data without modifying state.
Register the ThinAir Data MCP server in PolicyLayer and add a rule for explain_query: 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 ThinAir Data. Nothing to install.
explain_query 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 explain_query 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 explain_query. 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.
explain_query is provided by the ThinAir Data MCP server (thinairtelematics/thinair-data). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
