Ingest (upsert) a batch of products into the BuyWhere catalog. Use this to add or update product listings from any merchant/source. Requires a valid API key with ingest permissions. Accepts up to 1000 products per call with source, SKU, title, price, URL, and optional metadata.

AI agents use ingest_products to create or modify resources in BuyWhere MCP. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call ingest_products repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach BuyWhere MCP.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access ingest_products gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Ingest (upsert) a batch of products into the BuyWhere catalog. Use this to add or update product listings from any merchant/source. Requires a valid API key with ingest permissions. Accepts up to 1000 products per call with source, SKU, title, price, URL, and optional metadata.. It is categorised as a Write tool in the BuyWhere MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the BuyWhere MCP server in PolicyLayer and add a rule for ingest_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 BuyWhere MCP. Nothing to install.
ingest_products 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 ingest_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 ingest_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.
ingest_products is provided by the BuyWhere MCP server (https://api.buywhere.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
