# Square — AI Connector Square publishes 3 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/square/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # Square Square commerce, payment and inventory data in Claude Listed in Claude · 3 published tools · Verified partner [Claude connector docs](https://developer.squareup.com/docs/mcp) [squareup.com](https://squareup.com) Overview ## What Square does Square runs point-of-sale and commerce infrastructure for merchants. The listing describes a wide span of work: transaction data, customer profiles, inventory tracking, payment processing, sales analysis, financial reporting and point-of-sale operations. Against all of that it publishes three tools. That gap between described scope and published count is the most notable thing on this record. Partner tier applies, and the connector attaches to an existing Square merchant account under its own permissions. ### Who it is for Merchants and operations staff running a business on Square. ### Tool surface Three tools are published against a description covering payments, customers, inventory and reporting, and the endpoint will not name them, so how that breadth folds into so few calls is unresolved. Availability ## Where Square is listed Square is listed in the Claude connectors directory only. Square, Inc. has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Square publishes 3 tools to Claude, a deliberately narrow surface; only 11.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Finance publishes 12, so this one sits 9 tools below its bucket's median, 147th of 159. It falls in the 1-3 tools band, which holds 16.4% of the Claude directory. Square 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 Square, Inc. Verification Verified partner (37.8% of the Claude directory) Filed under Financial Services Endpoint `https://mcp.squareup.com/mcp` Documentation [Publisher setup docs](https://developer.squareup.com/docs/mcp) Published tools 3 · 1-3 tools band Depth rank in Finance 147 of 159 Snapshot August 2026 Square carries partner verification in the Claude directory, which 474 of 1,253 listings do (37.8%). That is a review step past self-publishing, not an Anthropic-built server.
