AI agents call search_packages to retrieve information from Gitsim Chat 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 search_packages 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 search_packages gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Search for eSIM data packages by country. Returns up to 10 packages per page sorted by price. Use the page parameter to paginate. No auth required. Call get_business_context first to understand IP routing and package types. Package types: - "regular": Fixed data pool (e.g. 3GB for 30 days). Best for most travelers. - "daily": Data resets each day (e.g. 2GB/day for 5 days). Good for short trips with predictable daily usage. Top-up days are available. IP routing (important for Asia): - "breakout": Local IP in destination country. Best for streaming, banking, social media. ALWAYS recommend by default. - "hk": Hong Kong IP. Cheapest but TikTok app and Facebook app are BLOCKED. - "nonhk": Third-country IP (UK, Singapore). No HK restrictions but IP won't match destination.. It is categorised as a Read tool in the Gitsim Chat MCP Server, which means it retrieves data without modifying state.
Register the Gitsim Chat MCP server in PolicyLayer and add a rule for search_packages: 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 Gitsim Chat. Nothing to install.
search_packages is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_packages 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 search_packages. 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.
search_packages is provided by the Gitsim Chat MCP server (https://chat.gitsim.com/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
