AI agents call run_analysis to retrieve information from SUMO-MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool analyzes FCD (Floating Car Data) output, which is a read/query operation on simulation result data. No side effects, modifications, or executions are implied. Confidence is moderate because the description is very brief and doesn't detail what 'analyze' entails, but analysis of output data is typically a read operation.
From the tool's definition Analyze FCD output
Documented attack patterns abuse exactly the kind of access run_analysis gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SUMO-MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for run_analysis:
{
"version": "1",
"default": "deny",
"tools": {
"run_analysis": {}
}
}run_analysis is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Analyze FCD output. It is categorised as a Read tool in the SUMO-MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SUMO-MCP Server MCP server in PolicyLayer and add a rule for run_analysis: 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 SUMO-MCP Server. Nothing to install.
run_analysis 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 run_analysis 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 run_analysis. 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.
run_analysis is provided by the SUMO-MCP Server MCP server (xrds76354/sumo-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
