AI agents call metrics to retrieve information from Codescan without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries metric data from Codescan without side effects. It fits the Read category definition: retrieves data with no side effects. The severity is low as accessing metrics poses minimal security risk—metrics are typically informational and non-sensitive aggregate data. Confidence is high based on the clear read-only semantics of the operation.
From the tool's definition Tool description states 'Get available metrics from Codescan' with no mention of modification, deletion, or execution. The server description confirms it enables 'retrieving metrics' and 'querying issues' as read-only operations.
Attacks that exploit this kind of access
Get available metrics from Codescan. It is categorised as a Read tool in the Codescan MCP Server, which means it retrieves data without modifying state.
Register the Codescan MCP server in PolicyLayer and add a rule for metrics: 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 Codescan. Nothing to install.
metrics 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 metrics 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 metrics. 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.
metrics is provided by the Codescan MCP server (presh-ar/codescan-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
