Organic Web Checker MCP server

Organic Web Checker — MCP Server

Cross-reference certified organic operation websites against live USDA Organic Integrity Database (OID) certificate data. Identifies organic product representations that may not be on the certificate of organic operation.

Status: Live · Remote HTTP MCP server · JSON-RPC 2.0 · API key required

• Endpoint: https://www.organicwebchecker.com/mcp
• Website: organicwebchecker.com
• Protocol: MCP 2024-11-05

What it does

Organic Web Checker (OWC) compares products marketed as organic on a certified operation's public website against the operation's live USDA OID certificate. It surfaces:

• ✅ Verified — product representation found on the cert
• 🔴 Flagged — organic representation with no matching cert item
• 🟡 Caution — close name variation, processing-form question, or grouped-scope match requiring review by the certifying agent

Built for organic certifying agents, compliance consultants, and certified operations doing self-review. Decision-support tool — not a compliance determination. Manual review of flagged items is required.

Tools

checkorganiccompliance

Returns: structured JSON report with verified, flagged, caution, marketing lists, cert metadata, and item-level URLs.

Cost: 1 credit per successful run.

getoidcertificate

Fetches an operation's current USDA OID certificate without running a website check.

Returns: certified products, certifier, status, location, scopes.

Regulatory context

OWC checks public-facing organic representations against publicly available OID certificate information. It acknowledges:

• Retail exemption — 7 CFR §205.101(a)(2)
• Handler/OSP scope — 7 CFR §205.201; detailed product coverage held by the certifying agent
• SOE rule (March 19, 2024) — brokers, traders, importers, exporters now require handler certification

Results are decision-support only. Final compliance determinations are made by certifying agents.
