AI agents call bulk_lookup to retrieve information from MCP CNPJ Intelligence without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs batch queries of company data from the Brazilian Federal Revenue database. It retrieves information about multiple companies by their CNPJ identifiers but does not create, modify, delete, or execute any operations. The design is explicitly for data lookup and enrichment workflows, with a hard limit of 100 CNPJs per request.
From the tool's definition Tool name 'bulk_lookup' and description 'Consulta MULTIPLOS CNPJs de uma vez (lote)' [Queries MULTIPLE CNPJs at once (batch)] with use cases limited to data enrichment and imports. No modification, deletion, execution, or financial operations are described.

bulk_lookup 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 bulk_lookup 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 bulk_lookup. 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.
bulk_lookup is provided by the MCP CNPJ Intelligence MCP server (raphaelmarra/mcp-cnpj-intelligence). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
