AI agents use update_prices to create or update resources in Wb — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Wb environment.
An AI agent can call update_prices faster than any human can review — one bad instruction and it creates or modifies resources in Wb by the hundred, each call as confident as the last.

Перед вызовом обязательно подтвердить у пользователя список артикулов и новых цен. It is categorised as a Write tool in the Wb MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Wb MCP server in PolicyLayer and add a rule for update_prices: 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 Wb. Nothing to install.
update_prices is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_prices 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 update_prices. 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.
update_prices is provided by the Wb MCP server (wb-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
