Get raw Lighthouse report data by ID (Layer 1)
AI agents call l1_get_report to retrieve information from Lighthouse MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing Lighthouse report data by identifier. It performs a read-only query operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an agent could only access report data that already exists, which would constitute information disclosure at worst but not operational impact.
From the tool's definition Tool name contains 'get_report' and description states 'Get raw Lighthouse report data by ID' — a retrieval operation with no modification, deletion, or execution.
Attacks that exploit this kind of access
Get raw Lighthouse report data by ID (Layer 1). It is categorised as a Read tool in the Lighthouse MCP MCP Server, which means it retrieves data without modifying state.
Register the Lighthouse MCP server in PolicyLayer and add a rule for l1_get_report: 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 Lighthouse MCP. Nothing to install.
l1_get_report 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 l1_get_report 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 l1_get_report. 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.
l1_get_report is provided by the Lighthouse MCP server (mizchi/lighthouse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
