Generate executable scraper/automation code from a comma-separated list of
AI agents invoke generate_scraper_code to trigger actions in Mitmproxy. 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.
The tool generates executable code for scraping/automation purposes. While it primarily generates code (which could be considered Write), the output is executable code designed to run against external systems, and in the context of mitmproxy (which intercepts HTTP/HTTPS traffic), this code could be used to automate requests, scrape data, or replay traffic against live systems.

Documented attack patterns abuse exactly the kind of access generate_scraper_code gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mitmproxy, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_scraper_code:
{
"version": "1",
"default": "deny",
"tools": {
"generate_scraper_code": {
"limits": [
{
"counter": "generate_scraper_code_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}generate_scraper_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.

Generate executable scraper/automation code from a comma-separated list of. It is categorised as a Execute tool in the Mitmproxy MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mitmproxy MCP server in PolicyLayer and add a rule for generate_scraper_code: 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 Mitmproxy. Nothing to install.
generate_scraper_code is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the generate_scraper_code 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.
Set action: deny in the PolicyLayer policy for generate_scraper_code. 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.
generate_scraper_code is provided by the Mitmproxy MCP server (snapspecter/mitmproxy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
