PocketSmith for AI agents

PocketSmith is a personal finance platform for tracking accounts and transactions, managing budgets, and forecasting cash flow. Individuals use it to plan their finances ahead of time. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How PocketSmith connects.

Users add their PocketSmith api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same PocketSmith connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

PocketSmith and Arc0, answered.

Q01

Can I use PocketSmith with Claude, ChatGPT or Cursor?

Yes. Connect PocketSmith to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the PocketSmith actions you allow.

Q02

How do users connect PocketSmith?

Users add their PocketSmith api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which PocketSmith actions can my agent take?

14 in total: 8 read, 6 write and 0 destructive, such as “create Category”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in PocketSmith?

Yes. Allow read actions and deny writes in the PocketSmith policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call PocketSmith too?

Yes. The same PocketSmith connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
