MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Stitch MCP Server tools

Destructive · High clear_workspace_project This tool permanently severs the link between a workspace and its associated Stitch project, eliminating the project's context and configuration from the current environment. Execute · High build_site This tool executes a site-building workflow with dependencies on project structure and configuration. Write · Medium apply_design_context This tool creates or modifies design screens within the Stitch workspace, which is a Write operation. Write · Medium batch_generate_screens This tool creates new design screens/artifacts.

18 of Stitch MCP Server's 36 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Stitch MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Stitch MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "clear_workspace_project": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "apply_design_context": {
    "limits": [
      {
        "counter": "apply_design_context_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "analyze_accessibility": {
    "limits": [
      {
        "counter": "analyze_accessibility_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Stitch MCP Server

Can an AI agent delete data through the Stitch MCP Server MCP server? +

Yes. The Stitch MCP Server server exposes 1 destructive tools including clear_workspace_project. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Stitch MCP Server? +

The Stitch MCP Server server has 16 write tools including apply_design_context, batch_generate_screens, edit_screens. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Stitch MCP Server.

How many tools does the Stitch MCP Server MCP server expose? +

36 tools across 4 categories: Destructive, Execute, Read, Write. 18 are read-only. 18 can modify, create, or delete data.

How do I enforce a policy on Stitch MCP Server? +

Register the Stitch MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Stitch MCP Server tool call.

Deterministic rules across all 36 Stitch MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
