AI agents use fda_import_refusals to create or modify resources in FDA Data 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 fda_import_refusals 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 FDA Data MCP.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Search FDA import refusals (Compliance Dashboard data, not available in openFDA API). Import refusals indicate products detained at the US border. Filter by company name, FEI number, country code (e.g., CN, IN for major API source countries), or date range. Critical for evaluating international manufacturing sites and supply chain risk. Related: fda_get_facility (facility details by FEI), fda_inspections (inspection history by FEI).. It is categorised as a Write tool in the FDA Data MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the FDA Data MCP server in PolicyLayer and add a rule for fda_import_refusals: 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 FDA Data MCP. Nothing to install.
fda_import_refusals 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 fda_import_refusals 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 fda_import_refusals. 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.
fda_import_refusals is provided by the FDA Data MCP server (https://www.regdatalab.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
