Notes and caveats

  • Uses Sandbox credentials (PLAID_CLIENT_ID and PLAID_SECRET from the Plaid Dashboard Keys page).
  • Version 0.1.1 (2026-08-10) pins the mcp SDK below 2.0 after mcp 2.0.0 broke startup of 0.1.0 under uvx.
  • If installed via pip, swap uvx mcp-server-plaid for python -m mcp_server_plaid.
  • No status label on vendor pages.
