No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/contaminants_max_levels for the schema, then POST the same URL with its arguments for the data.

Codex Alimentarius maximum levels (MLs) for a contaminant in food — lead, cadmium, arsenic, mercury, methylmercury, tin, aflatoxins, ochratoxin A, patulin, melamine, hydrocyanic acid. Returns each commodity with its maximum level, the unit it is expressed in, and the page of CXS 193 it came from. Use for “what is the Codex limit for lead in fish” or “which foods have cadmium maximum levels”.
