Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint.

Coverage spans sales and profit, inventory levels, reviews, inbound shipments, advertising performance, and traffic on listings. Everything runs one way. The app reads store data and returns answers, but makes no changes to the account, so questions about marketplace status or period over period performance carry no risk of altering settings or listings. That framing puts it in the reporting category rather than the seller tooling category: suited to asking where profit moved last month or which shipments are still inbound, not to editing campaigns. ### Who it is for Amazon sellers and their operations staff who want account figures summarised in conversation. ### What stands out The read-only design covers advertising and traffic data as well as the usual sales and inventory views. Availability ## Where Tool4seller is listed Tapcash Inc. ships this on both marketplaces: Tool4seller is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain. Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

The median Claude-listed connector filed under Data & Analytics publishes 12, so this one runs 9 tools above its bucket's median and ranks 43rd of 198 by tool count. It falls in the 21-50 tools band, which holds 20% of the Claude directory. ### Measured against the live endpoint A direct call to the endpoint returned 21 tools, matching the 21 the listing publishes. Probed 2026-08-07. #### Tools the server actually returns - `diagnose_ad_efficiency` - `diagnose_profit_anomaly` - `diagnose_sales_change` - `discover_capabilities` - `get_current_user` - `inventory_risk_review` - `list_inbound_shipment_items` - `list_inbound_shipments` - `list_stores` - `query_advertising` - `query_advertising_campaigns` - `query_advertising_purchased_products` - `query_advertising_search_terms` - `query_advertising_targets` - `query_inventory` - `query_inventory_alerts` - `query_profit` - `query_review_ratings` - `query_sales` - `query_sales_traffic` - `query_store_health` Tool4seller publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Tapcash Inc. Verification Community-listed (61.5% of the Claude directory) Filed under Data & Analytics Endpoint `https://das-server.tool4seller.com/mcp` Documentation [Publisher setup docs](https://www.tool4seller.com/faqs/faq-use-tool4seller-mcp-with-ai/) Published tools 21 · 21-50 tools band Depth rank in Data & Analytics 43 of 198 Snapshot August 2026 Tool4seller is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Tapcash Inc. describes it > Tool4seller connects Claude to your authorized Amazon seller data through a secure, read-only connector. Ask Claude to analyze sales and profit performance, review advertising campaigns and targeting metrics, monitor inventory and inventory alerts, inspect sales traffic, track product reviews, and check FBA inbound shipments across your connected Amazon stores. The connector supports store-level and product-level reporting, multi-store comparisons, advertising performance analysis, and advanced targeting searches using metrics such as clicks, orders, ACoS, CTR, and conversion rate. Access is authorized through OAuth and limited to the stores and permissions available in your Tool4seller account. The connector is read-only: it does not modify Amazon listings, inventory, orders, campaigns, bids, or budgets. Quoted from the connector's own Claude directory listing as captured in August 2026. Node8 did not write it and does not vouch for it.
