WHAT IT DOES

What generate_qr_code does on ContextForge MCP Gateway

AI agents invoke generate_qr_code to trigger actions in ContextForge MCP Gateway. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why generate_qr_code is rated High

Generating a QR code involves executing a process that produces an output artifact. It is not a simple read, nor does it write persistent data, delete anything, or involve finances. It falls under Execute as it triggers a code-generation operation.

From the tool's definition 'Generate QR code' — triggers an external operation to produce a QR code artifact

RECOMMENDED RULE

The rule that runs generate_qr_code safely

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

generate_qr_code Rate-limited

generate_qr_code stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

policy.json

    "generate_qr_code": {
      "limits": [
        {
          "counter": "generate_qr_code_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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