Get the files with the highest blast radius — most other files depend on them.
AI agents call get_high_impact_files to retrieve information from Carto MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about codebase dependencies to inform decision-making. It queries existing data about file impact and dependency relationships without creating, modifying, deleting, or executing any code. While the information could inform risky decisions, the tool itself performs no side effects.
From the tool's definition Tool name and description indicate retrieval operations: 'Get the files' and 'enables AI coding tools to query your live codebase'. The description explicitly states it identifies dependencies and structure without modifying anything.
Documented attack patterns abuse exactly the kind of access get_high_impact_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Carto MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_high_impact_files:
{
"version": "1",
"default": "deny",
"tools": {
"get_high_impact_files": {}
}
}get_high_impact_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the files with the highest blast radius — most other files depend on them. It is categorised as a Read tool in the Carto MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Carto MCP Server MCP server in PolicyLayer and add a rule for get_high_impact_files: 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 Carto MCP Server. Nothing to install.
get_high_impact_files 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 get_high_impact_files 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 get_high_impact_files. 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.
get_high_impact_files is provided by the Carto MCP Server MCP server (theanshsonkar/carto). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
