Attacks that exploit this kind of access
The rule that runs mysql_spatial_distance_sphere safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_spatial_distance_sphere, this is the rule to start with:
mysql_spatial_distance_sphere 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 Mysql Mcp, apply this rule, and every mysql_spatial_distance_sphere call is checked against it from then on.
Questions about mysql_spatial_distance_sphere
Calculate distance on a sphere (for geographic coordinates). Returns distance in meters. It is categorised as a Read tool in the Mysql Mcp MCP Server, which means it retrieves data without modifying state.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_spatial_distance_sphere: 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 Mysql Mcp. Nothing to install.
mysql_spatial_distance_sphere 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 mysql_spatial_distance_sphere 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 mysql_spatial_distance_sphere. 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.
