SpherePay Server

A Model Context Protocol server for the SpherePay payment platform. Manage customers, bank accounts, wallets, transfers, virtual accounts, webhooks, and CCTP off-ramps directly from Claude.

Features

• 24 curated tools — 9 workflow tools for multi-step operations, 15 read-only tools for instant lookups
• Automatic retries with exponential backoff and rate limit handling
• Idempotency for transfers — duplicate requests are safely deduplicated
• PII redaction in logs — account numbers, routing numbers, and personal data are never logged
• Input validation at the tool boundary — IDs, currencies, networks, and amounts are validated before any API call
• Desktop Extension (.mcpb) for one-click Claude Desktop installation
