Attacks that exploit this kind of access
The rule that runs opensensemap.sensors.latest safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For opensensemap.sensors.latest, this is the rule to start with:
opensensemap.sensors.latest 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 Apibase, apply this rule, and every opensensemap.sensors.latest call is checked against it from then on.
Questions about opensensemap.sensors.latest
Get the latest measurement value for every sensor on an OpenSenseMap station in a single call. Returns all sensor readings simultaneously: temperature, humidity, pressure, PM2.5, PM10, UV, CO₂, and any other sensors installed on the station. Each reading includes sensor ID, title, unit, sensor type, current value, and timestamp of measurement. Sensors with no recent data show last_value: null. Use box_search or box_detail to find the box_id first, then use sensor IDs from results with sensor_timeseries for historical data. Ideal for real-time environmental monitoring dashboards. Source: OpenSenseMap, PDDL 1.0 public domain. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
opensensemap.sensors.latest accepts 1 parameter: box_id. Required: box_id. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for opensensemap.sensors.latest: 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 Apibase. Nothing to install.
