What overview does on Ncp
AI agents call overview to retrieve information from Ncp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why overview is rated Low
The tool retrieves and displays analytics data (usage stats, performance metrics, trends) in a read-only dashboard format. It has no side effects — it only queries and formats existing data for display. Severity is low as misuse would only expose monitoring/telemetry information.
From the tool's definition 'Visual analytics dashboard...showing usage stats, token savings, performance metrics, and trends. Returns formatted in markdown code blocks for rendering.'
Attacks that exploit this kind of access
The rule that runs overview safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For overview, this is the rule to start with:
overview 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 Ncp, apply this rule, and every overview call is checked against it from then on.
Questions about overview
Visual analytics dashboard with ASCII charts showing usage stats, token savings, performance metrics, and trends. Returns formatted in markdown code blocks for rendering. It is categorised as a Read tool in the Ncp MCP Server, which means it retrieves data without modifying state.
Register the Ncp MCP server in PolicyLayer and add a rule for overview: 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 Ncp. Nothing to install.
overview 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 overview 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 overview. 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.
overview is provided by the Ncp MCP server (@portel/ncp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
