What's New in v2.3

Seller Central AJAX lookup - Fetch Amazon's live Seller Central listing JSON with catalog listing fetch <asin>
Live listing vs CLR diff - Compare Amazon's current listing fields against your Category Listing Report with catalog listing diff <asin> <clr-file>
Agent-ready Seller Central tools - New MCP tools catalog_seller_listing_fetch and catalog_seller_listing_diff
Local cookie auth - Use --cookie, --cookie-file, or CATALOG_SELLER_CENTRAL_COOKIE; Seller Central cookies stay local

v2.2 Title Readiness

Amazon title readiness - mobile-title-readiness flags titles over 75 characters for Amazon's mobile title update
Rewrite-ready output - Returns first-75-character title segments, overflow text, significant terms, item highlight status, and recommended next actions
Agent workflow friendly - Aliases title-75 and amazon-title-75 make it easy to call from Claude, MCP clients, and automation workflows
14 built-in checks - Adds a title triage workflow while keeping the classic 200-character long-titles check unchanged

v2.0 Agent Foundations

Shared core architecture - Business logic separated into catalog/core/, powering both CLI and MCP
MCP server - catalog mcp launches a stdio MCP server with 4 tools, ready for Claude Desktop and any MCP client
JSON input - --json and --stdin flags for structured agent input
Schema introspection - catalog schema --format json returns full request/response schemas
Field masks - --fields sku,severity,details to reduce output size
Pagination - --limit and --offset for controlling result size
NDJSON streaming - --format ndjson for line-by-line streaming of large results
Input hardening - Pydantic validation rejects path traversal, injection, and malformed input
Environment variables - CATALOG_CLI_DEFAULT_FORMAT=json for headless/CI use
Backward compatible - All v1.x commands work unchanged

bash

# Free (local) — data stays on your machine
catalog setup-claude

# Pro (hosted API) — persistent storage, unlimited scans
catalog setup-claude --pro --api-key YOUR_KEY

# Per-project instead of global
catalog setup-claude --project

After setup, restart Claude Code and try: "Scan my-catalog.xlsx and tell me the biggest issues"

Example JSON Output

json

{
  "timestamp": "2026-03-05T10:30:00Z",
  "marketplace": "US",
  "is_us_marketplace": true,
  "total_queries": 14,
  "total_issues": 47,
  "total_affected_skus": 23,
  "results": [
    {
      "query_name": "missing-attributes",
      "description": "Find mandatory attributes missing from listings",
      "total_issues": 12,
      "affected_skus": 8,
      "issues": [
        {
          "row": 7,
          "sku": "ABC-123",
          "field": "brand",
          "severity": "required",
          "details": "Missing required field: brand",
          "product_type": "HAIR_STYLING_AGENT",
          "extra": {}
        }
      ]
    }
  ]
}

Agent Integration

Via CLI (subprocess)

python

import subprocess, json

result = subprocess.run(
    ['catalog', 'scan', 'my-catalog.xlsx', '--format', 'json',
     '--fields', 'sku,severity,details', '--limit', '20'],
    capture_output=True, text=True
)
data = json.loads(result.stdout)

Via Python (direct import)

python

from catalog.core import execute_scan, ScanRequest

request = ScanRequest(
    file="my-catalog.xlsx",
    queries=["missing-attributes", "intent-bullets"],
    fields=["sku", "severity", "details"],
    limit=20,
)
response = execute_scan(request)

Via MCP

Add the MCP server to any MCP client (Claude Desktop, CLR Pro, etc.) and call catalog_scan, catalog_check, catalog_seller_listing_fetch, catalog_seller_listing_diff, catalog_list_queries, or catalog_schema.

Intent-Based Bullet Optimization

The intent-bullets query evaluates bullet points against COSMO-inspired shopper intent coverage:

Audience / need fit: Who it is for, preferences, or problem state
Function / use case: The job, activity, event, or use flow
Context / compatibility: Where, when, or what it works with
Decision evidence: Specs, attributes, trust signals, or differentiators
All bullets: Checked for intent coverage, length, vague marketing, ALL CAPS

Scores 1-5 with actionable suggestions. The old rufus-bullets query name still works as a deprecated compatibility alias.

Extending with Custom Queries

python

from catalog.query_engine import QueryPlugin

class MyCustomQuery(QueryPlugin):
    name = "my-custom-check"
    description = "My custom catalog check"

    def execute(self, listings, clr_parser):
        issues = []
        for listing in listings:
            if some_condition:
                issues.append({
                    'row': listing.row_number,
                    'sku': listing.sku,
                    'field': 'FieldName',
                    'severity': 'warning',
                    'details': 'Issue description',
                    'product_type': listing.product_type
                })
        return issues
