Why analyze_legacy_imports needs a policy

This tool performs static analysis to identify and catalog imports from legacy versions. It retrieves information about code structure ('scanner', 'imports and symbols') but does not execute code, modify files, or trigger side effects. The verb 'analyze' and noun 'scanner' both indicate Read-category behavior—querying existing data for inspection purposes.

From the tool's definition Tool name 'analyze_legacy_imports' combined with description 'Quick heuristic scanner for HeroUI/NextUI v2 imports and symbols' indicates a scanning/analysis operation that queries and examines code structure without modifying it.

POLICY

How to control analyze_legacy_imports

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 analyze_legacy_imports:

policy.json

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

analyze_legacy_imports 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 analyze_legacy_imports

What does the analyze_legacy_imports tool do? +

Quick heuristic scanner for HeroUI/NextUI v2 imports and symbols. 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 analyze_legacy_imports? +

Register the HeroUI Migration MCP server in PolicyLayer and add a rule for analyze_legacy_imports: 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 analyze_legacy_imports? +

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

Can I rate-limit analyze_legacy_imports? +

Yes. Add a rate_limit block to the analyze_legacy_imports 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 analyze_legacy_imports completely? +

Set action: deny in the PolicyLayer policy for analyze_legacy_imports. 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 analyze_legacy_imports? +

analyze_legacy_imports 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.
