AI agents call business.naics to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only lookups and searches against a public classification database. It returns structured data (titles, hierarchies, descriptions, activity index terms) without creating, modifying, deleting, or executing anything. The use case (KYC, registrations, ERP setup) involves data retrieval for reference, not side effects. Minimal blast radius if misused by an AI agent.
From the tool's definition Tool retrieves NAICS classification codes and descriptions from public domain US Census data. Supports 'Pass code for an exact NAICS code → official title, hierarchy path, full description' and 'pass query for free-text search → ranked candidate codes'.

NAICS 2022 industry classification codes (US Census, public domain). Pass code for an exact NAICS code (2-6 digits, or a sector range like 31-33) → official title, hierarchy path, full description, activity index terms, and direct child codes. Or pass query for free-text search over titles + the official ~20k-entry activity index → ranked candidate codes, optionally filtered by level (2=sector … 6=national industry). Ground truth for industry coding in KYC, registrations, and ERP setup. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for business.naics: 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 Mcp. Nothing to install.
business.naics 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 business.naics 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 business.naics. 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.
business.naics is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
