inject_cookie · Suno Autopilot MCP: Risk & Policy

WHAT IT DOES

What inject_cookie does on Suno Autopilot MCP

AI agents invoke inject_cookie to trigger actions in Suno Autopilot MCP. 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.

WHY IT NEEDS A POLICY

Why inject_cookie needs a policy

The tool name 'inject_cookie' strongly implies injecting a cookie into a browser session, which is a browser automation action (Execute category). In the context of this server, which uses browser automation to interact with Suno, injecting a cookie likely sets authentication credentials in the browser. This could allow session hijacking or unauthorized account access if misused, warranting high severity.

From the tool's definition Tool name 'inject_cookie' and server description mentions 'browser automation' and 'validate_cookie' sibling tool

Verdict

inject_cookie Rate-limited

inject_cookie 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.

What risk level is inject_cookie? +

inject_cookie is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit inject_cookie? +

Yes. Add a rate_limit block to the inject_cookie 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 inject_cookie completely? +

Set action: deny in the PolicyLayer policy for inject_cookie. 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 inject_cookie? +
