Nexafin is an AI-powered personal finance platform for connecting bank accounts or imported statements, tracking balances, transactions, and recurring bills. It lets users query and analyze their financial data through a REST API and AI integrations.
Nexafin exposes a REST Public API at https://app.nexafin.com/v1 authenticated by Nexafin API keys, plus MCP endpoints at https://app.nexafin.com/mcp (OAuth 2.1) and https://nexafin.com/mcp (catalog-detected public endpoint).

Sign in to the Nexafin app, open Settings → API Keys, and create a key. Copy it when shown — the full key is only displayed once. Keys use the nxfn_sk_ prefix and expire after 1 year. The Public API is a PRO-account feature.
For custom MCP clients, register an OAuth client against Nexafin's WorkOS/AuthKit authorization server using the dynamic client registration endpoint, then run the standard OAuth authorization-code flow against authorize and token. Supported scopes published by the server are openid, profile, email, and offline_access. Most MCP clients handle this automatically when you connect to the MCP URL, so manual registration is usually unnecessary.
