We’d like to enable our customers to connect Square and use your MCP tools (orders, customers, catalog, payments).
Requesting our domain on your MCP client allowlist:
-
Client name: Keycard
-
Domain to allow: keycard.cloud (subdomains too: *.keycard.cloud)
-
Issuer URL: https://.keycard.cloud
-
Redirect URL: https://.keycard.cloud/oauth/2/redirect
Worth noting: Keycard is a proxy between our customer’s AI client and your MCP server, so you’ll see Keycard as the client rather than the end tool (Cursor, Claude, etc.). We complete OAuth, vault the token, and pass it to the customer’s client via token exchange.
Happy to share anything else you need.
