Hi Square Team!
We’re the engineering team at Littlebird (littlebird.ai) - an AI productivity assistant. We’d love to enable our users to connect their Square accounts and access Square tools (orders, customers, catalog, payments) through your MCP server.
Domain to allow: littlebird.ai
Client name: Littlebird
We’ve already verified that https://mcp.squareup.com/.well-known/oauth-authorization-server returns 200 and surfaces a /register endpoint, but our DCR attempts return a 400 - which we understand is the allowlist gate.
Happy to provide any additional info or credentials needed. Thanks!
