WHAT IT DOES

What scaffold_project_files does on Stitch MCP Server

AI agents use scaffold_project_files to create or update resources in Stitch MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stitch MCP Server environment.

RISK

Why scaffold_project_files is rated Medium

This tool creates or modifies local files on the user's system by writing UI design data to specified file paths. While reversible (files can be edited or deleted), it definitively alters the local filesystem. It does not execute arbitrary code, delete irreversibly, or move money, so Write is the correct category.

From the tool's definition Tool description states it 'Maps a specific screen from a project to a local file path' and 'save UI designs directly into the user' (user's local environment)—these are write operations that create or modify files on disk.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs scaffold_project_files safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Stitch MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scaffold_project_files, this is the rule to start with:

scaffold_project_files Rate-limited

scaffold_project_files stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "scaffold_project_files": {
      "limits": [

          "counter": "scaffold_project_files_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Stitch MCP Server, apply this rule, and every scaffold_project_files call is checked against it from then on.

FAQ

Questions about scaffold_project_files

What does the scaffold_project_files tool do? +

Maps a specific screen from a project to a local file path. Use this to save UI designs directly into the user. It is categorised as a Write tool in the Stitch MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on scaffold_project_files? +

Register the Stitch MCP Server MCP server in PolicyLayer and add a rule for scaffold_project_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 Stitch MCP Server. Nothing to install.

What risk level is scaffold_project_files? +

scaffold_project_files is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit scaffold_project_files? +

Yes. Add a rate_limit block to the scaffold_project_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.

How do I block scaffold_project_files completely? +

Set action: deny in the PolicyLayer policy for scaffold_project_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.

What MCP server provides scaffold_project_files? +

scaffold_project_files is provided by the Stitch MCP Server MCP server (0x-professor/stitch-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
