List external products for an integration. GET /integrations/{integrationId}/products. Required: integrationId, productName (sent as name query param).
AI agents call list_external_products to retrieve information from Rebillia MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves product data from an external integration without creating, modifying, deleting, or executing any operations. The GET endpoint with filtering parameters (integrationId, productName) is a standard read operation with minimal blast radius—it only returns data matching the query criteria.
From the tool's definition Tool name 'list_external_products' and description 'List external products' indicate a retrieval operation. HTTP method is GET, which is a read-only operation. No modifications, deletions, or financial transactions occur.

Register the Rebillia MCP Server MCP server in PolicyLayer and add a rule for list_external_products: 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 Rebillia MCP Server. Nothing to install.
list_external_products 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 list_external_products 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 list_external_products. 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.
