Introducing Era: AI-Native Personal Finance via MCP

Era is a personal finance platform that connects your bank accounts to any AI assistant via the Model Context Protocol (MCP). Instead of locking you into one chatbot, Era lets Claude, ChatGPT, Gemini, or any MCP-compatible agent read your financial data, generate insights, and trigger automations on your behalf.

What is the Model Context Protocol?

MCP is an open standard that lets AI agents securely access external data and tools through a uniform interface. Think of it as a USB-C port for AI: any compliant client plugs in, authenticates, and gets structured access to the host application's capabilities. Anthropic published the spec in late 2024, and adoption has grown rapidly across developer tooling, enterprise platforms, and now personal finance.

How does Era use MCP?

When you connect your bank accounts through Era, the platform aggregates balances, transactions, and account metadata from over 12,000 financial institutions via Plaid and MX. Era then exposes this data through a standards-compliant MCP server. Your AI agent of choice connects to that server, authenticates with your credentials, and gains read and write access to a curated set of financial tools.

Available tools include querying transaction history, categorizing spending, creating automated money movement rules, and retrieving account balances. Every tool call is scoped by the permissions you grant -- your agent cannot exceed the access level you define.

Which AI agents work with Era?

Any agent that implements the MCP client specification can connect. Today that includes Claude Desktop, ChatGPT (via plugin bridge), Cursor, Windsurf, and a growing list of open-source clients. Era also ships Agency, a first-party AI companion built directly into the app for users who prefer a turnkey experience.

Is my financial data secure?

Era uses bank-level AES-256 encryption for data at rest and TLS 1.3 for data in transit. All MCP connections require OAuth 2.1 authentication with scoped permissions. Your credentials are never stored on Era servers -- Plaid and MX handle credential management through their own SOC 2 Type II-certified infrastructure. Every tool invocation is logged, auditable, and revocable from your Era dashboard.
