This tool generates composite operational analytics reports by combining multiple data sources. Use it for high-level business questions about space utilization, traffic patterns, and real-time scene analysis. It has the following modes of operation, determined by the "requestType" parameter: -...
Part of the Rhombus Node MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call analytics-tool to retrieve information from Rhombus Node without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though analytics-tool only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

This tool generates composite operational analytics reports by combining multiple data sources. Use it for high-level business questions about space utilization, traffic patterns, and real-time scene analysis. It has the following modes of operation, determined by the "requestType" parameter: - space-utilization: Compare per-camera people counts against running averages at a location. Answers: "How busy is each area vs normal?" - traffic-flow: Compare ingress/egress across ALL line-crossing cameras at a location. Answers: "Which entrance gets the most traffic?" - peak-vs-average: Show hourly actual counts vs historical averages. Answers: "When is it busiest? Is today above or below normal?" - scene-intelligence: Ask a camera an arbitrary question using AI vision (e.g. "How many treadmills are in use?"). Works in real-time or at a historical timestamp. - location-summary: Generate a comprehensive multi-metric analytics summary for a location including people counts, traffic flow, and trend comparisons. **Output filtering (all tools):** - `includeFields` (string[]): Dot-notation paths to keep in the response (e.g. `"vehicleEvents.vehicleLicensePlate"`). Omit to return all fields. - `filterBy` (array): Predicates to filter array items. Each entry: `{field, op, value}` where op is one of `= != > >= < <= contains`. All conditions are ANDed. Example: `[{field:"vehicleLicensePlate", op:"=", value:"ABC123"}]` WARNING: some tool responses exceed 400k characters — use these params to request only the data you need.. It is categorised as a Read tool in the Rhombus Node MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for analytics-tool. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Rhombus Node MCP server.
analytics-tool 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 analytics-tool rule in your Intercept 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 Intercept policy for analytics-tool. 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.
analytics-tool is provided by the Rhombus Node MCP server (rhombus-node-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
