Get the full product type/categories map. It
AI agents call categories to retrieve information from Bitrefill MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool returns reference data (product categories) for display or filtering purposes. No data is created, modified, deleted, or financial transactions are triggered. The blast radius of accidental misuse is minimal—worst case, stale category data is retrieved.
From the tool's definition Tool retrieves a 'full product type/categories map' with no modifications, deletions, or financial operations. The verb 'Get' and noun 'map' indicate a read-only query operation.

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