MOST DANGEROUS TOOLS
Critical Risk

The most dangerous GadgetHumans API Hub tools

Destructive · High clean_whitespace Remove redundant whitespace: extra spaces, tabs, newlines, or all. Destructive · High gravitational_force_calc Calculate gravitational force between two masses using Newton's law. Execute · Medium generate_password Based on the tool name and server context (utility APIs including passwords), this tool likely generates a password string. Execute · Low atbash_cipher The tool performs a text transformation operation (cipher encoding/decoding) rather than simply retrieving data.

48 of GadgetHumans API Hub's 311 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control GadgetHumans API Hub

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

Deny destructive operations
{
  "clean_whitespace": {
    "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
{
  "comment_strip": {
    "limits": [
      {
        "counter": "comment_strip_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "alternating_case": {
    "limits": [
      {
        "counter": "alternating_case_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

  1. Create a free account and register GadgetHumans API Hub — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about GadgetHumans API Hub

Can an AI agent delete data through the GadgetHumans API Hub MCP server? +

Yes. The GadgetHumans API Hub server exposes 2 destructive tools including clean_whitespace, gravitational_force_calc. 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 GadgetHumans API Hub? +

The GadgetHumans API Hub server has 27 write tools including comment_strip, convert_color, convert_csv_to_json. 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 GadgetHumans API Hub.

How many tools does the GadgetHumans API Hub MCP server expose? +

311 tools across 4 categories: Destructive, Execute, Read, Write. 263 are read-only. 48 can modify, create, or delete data.

How do I enforce a policy on GadgetHumans API Hub? +

Register the GadgetHumans API Hub 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 GadgetHumans API Hub tool call.

Deterministic rules across all 311 GadgetHumans API Hub tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
