scan_project

THE RISK

Low Risk

Why scan_project needs a policy

The tool retrieves and indexes information about legacy component usage within a project filesystem. It has no side effects: it does not modify, delete, execute, or move money. The operation is purely informational to support migration auditing, making it a Read category risk with low severity.

From the tool's definition Tool performs recursive directory scanning and file analysis with 'scans a directory for files' — a read-only operation with no modification, deletion, or execution of code.

POLICY

How to control scan_project

PolicyLayer is an MCP gateway — it sits between your AI agents and HeroUI Migration MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for scan_project:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "scan_project": {}
  }
}

scan_project is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register HeroUI Migration MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about scan_project

What does the scan_project tool do? +

Recursively scans a directory for files using legacy HeroUI/NextUI components. It is categorised as a Read tool in the HeroUI Migration MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on scan_project? +

Register the HeroUI Migration MCP server in PolicyLayer and add a rule for scan_project: 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 HeroUI Migration MCP. Nothing to install.

What risk level is scan_project? +

scan_project is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit scan_project? +

Yes. Add a rate_limit block to the scan_project 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.

How do I block scan_project completely? +

Set action: deny in the PolicyLayer policy for scan_project. 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.

What MCP server provides scan_project? +

scan_project is provided by the HeroUI Migration MCP server (sctg-development/heroui-migration-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every HeroUI Migration MCP tool call.

Start from HeroUI Migration MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
