WHAT IT DOES

What sendWebhookData does on Spline MCP Server

AI agents invoke sendWebhookData to trigger actions in Spline MCP Server. 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 sendWebhookData is rated High

Sending webhook data constitutes triggering an external operation — it dispatches HTTP requests to external systems whose effects depend on the payload and target URL. This falls under Execute as it triggers external operations. Severity is high because misuse could send arbitrary data to external endpoints, potentially causing unintended side effects in third-party systems.

From the tool's definition Tool name 'sendWebhookData' implies sending data to an external webhook endpoint, which triggers external operations.

RECOMMENDED RULE

The rule that runs sendWebhookData safely

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

sendWebhookData Rate-limited

sendWebhookData 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.

  "tools": {
    "sendWebhookData": {
      "limits": [
        {
          "counter": "sendwebhookdata_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 Spline MCP Server, apply this rule, and every sendWebhookData call is checked against it from then on.
