Plaid MCP Server

Capable, but hard to hand over unsupervised.

Infrastructure, not an app: powerful read surface across thousands of banks, but client secrets, Link and production approval make it the hardest setup in the category.

What it costs to let an agent act

Paid planUsage-metered

Sandbox is free; production access requires a Plaid contract and per-item billing. Link flow needs an end-user session, which agents cannot complete alone.
