system_info is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call system_info to retrieve information from BoostedTravel 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 system_info 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.

These attack patterns abuse exactly the kind of access system_info gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so system_info only ever does what you allow.

What does the system_info tool do? +

Get system resource info (RAM, CPU cores) and recommended concurrency settings. Use this to determine optimal max_browsers value for search_flights. Returns RAM total/available, CPU cores, recommended max browsers, and performance tier. Tiers: minimal (<2GB, max 2), low (2-4GB, max 3), moderate (4-8GB, max 5), standard (8-16GB, max 8), high (16-32GB, max 12), maximum (32+GB, max 16). Read-only, no side effects, instant response.. It is categorised as a Read tool in the BoostedTravel MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on system_info? +

Register the BoostedTravel MCP server in PolicyLayer and add a rule for system_info: 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 BoostedTravel. Nothing to install.

What risk level is system_info? +

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

Can I rate-limit system_info? +

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

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

system_info is provided by the BoostedTravel MCP server (https://api.boostedchat.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every BoostedTravel tool call.
