Part of the Chrome MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call download to retrieve information from Chrome without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though download only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the download tool do? +

Check status of file downloads or list all downloaded files in this session. Downloads happen automatically when you click download links or navigate to files (PDFs, CSVs, etc.) — you do NOT need to call this tool to trigger downloads. Use this tool to: - Wait for a large download to finish: download() - List all downloaded files: download({ action: "list" }). It is categorised as a Read tool in the Chrome MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on download? +

Add a rule in your Intercept YAML policy under the tools section for download. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Chrome MCP server.

What risk level is download? +

download is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit download? +

Yes. Add a rate_limit block to the download rule in your Intercept 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 download completely? +

Set action: deny in the Intercept policy for download. 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 download? +

download is provided by the Chrome MCP server (@silbercue/chrome). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
