NAICS/SIC Classification API MCP. Audit industry codes, classify markets by keyword.

You're auditing industry codes? You don't guess. Your agent uses the NAICS/SIC Classification API server to verify precise business data instantly. This lets you look up North American Industry Classification System (NAICS) and Standard Industrial Classification (SIC) numbers by keywords or code IDs, pulling back full metadata and hierarchical context straight into your chat window.

To start, you'll first check the service health; calling check_api_status confirms if the NAICS/SIC classification service is running correctly. This tells you whether the server is operational before you try to pull any data. The primary function of this setup is searching: your agent runs search_naics_codes when you need to find NAICS codes, simply by passing keywords to the tool; it returns a list of matching North American Industry Classification System identifiers that fit those terms.

Separately, if you're tracking historical data or using older standards, calling search_sic_codes lets your agent locate Standard Industrial Classification codes based on specific search keywords. These two searching tools give you broad coverage across the industry landscape.

Once you get a list of potential identifiers, you might need more than just the code number—you'll need the details. For deep research, your agent uses get_classification_details to pull the full description and unique metadata for any specific NAICS or SIC code ID. You provide the code, and it gives you all the background information and context markers associated with that classification.

This mechanism ensures you know exactly what a code represents before you trust it.

You can structure your workflow around these capabilities: First, you'll check check_api_status to confirm connectivity. Next, if you want NAICS codes, you send keywords to search_naics_codes, which returns matching identifiers and associated metadata. If you need SIC codes instead, you pass those same keywords into search_sic_codes. After you identify a promising code from either search result, you use get_classification_details by providing the exact NAICS or SIC ID to retrieve its complete description and all available unique categorization markers.

This server lets your AI client audit complex industry data without needing any external portals. When your agent pulls classification codes, it provides both the primary identifier and comprehensive metadata for every result you ask about. You're not just getting a number; you're getting verified context that shows how an industry segment fits into the larger economic structure.

It’s perfect for competitive analysis or market research where data integrity is everything.
