cdp_connect · CDP-MCP Server MCP: Risk & Policy

WHAT IT DOES

What cdp_connect does on CDP-MCP Server

AI agents invoke cdp_connect to trigger actions in CDP-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.

WHY IT NEEDS A POLICY

Why cdp_connect needs a policy

This tool either attaches to an existing browser process or spawns a new one. Launching or attaching to a browser process is an external operation with significant blast radius — once connected, an AI agent gains access to the full CDP surface (arbitrary JS execution, network interception, DOM manipulation, credential access, etc.).

Verdict

cdp_connect Rate-limited

cdp_connect 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.

How do I enforce a policy on cdp_connect? +

Register the CDP-MCP Server MCP server in PolicyLayer and add a rule for cdp_connect: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches CDP-MCP Server. Nothing to install.

What risk level is cdp_connect? +

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

Can I rate-limit cdp_connect? +

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

Set action: deny in the PolicyLayer policy for cdp_connect. 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.
