Is this safe to run against production Plaid accounts? Will the AI transfer money?

Yes, it is entirely safe. We deliberately designed the 20 tools purely for deep inspection (fetching assets, checking IDs, balancing ledgers). Endpoints capable of moving capital (like `/transfer/create`) were excluded. The worst the AI can do is give you a highly detailed dashboard of your expenses.

How does the agent analyze different bank accounts when I talk to it?

You hold the master Server keys (Client ID and Secret). When you ask the agent a question, you just paste or mention the unique `access_token` representing that customer's bank connection, and the AI automatically uses it under the hood.

Can it cross check watchlists (AML) and biometrics?

Yes. Tools like `get_watchlist_screening` and `get_identity_verification` hook directly into Plaid Identity, matching end-users to PEP (Politically Exposed Persons), OFAC, and global government watchlists instantaneously.
