Overview

AI-generated overview

Lets an assistant read Stripe payouts, bank transactions, balances, and reconciliation discrepancies through the FlowCheck API.

What you can do
FlowCheck exposes tools for reading Stripe payouts, Plaid bank transactions, combined balances, daily cash flow, and reconciliation discrepancies, plus a 30-day financial health score and a full position snapshot. It also includes account registration, Stripe connection, Plaid bank linking, and webhook management tools.
When to use it
Useful when an assistant needs to answer questions about payout matching, missing deposits, cash flow, or overall financial position across Stripe and a bank account, without opening the FlowCheck dashboard.
Requirements
Runs locally via npx from the npm package @flowcheck/mcp-server, so Node.js is needed. Requires a FlowCheck API key in the FLOWCHECK_API_KEY environment variable; an optional FLOWCHECK_BASE_URL can override the API endpoint. Network access to the FlowCheck API is required.
Before you install
The API key is a live financial credential (fc_live_...), so store it carefully. Tools can connect a Stripe restricted key, start and complete a Plaid bank connection, and create or delete webhook endpoints, which changes account configuration. Financial data is sent to the FlowCheck API.

Installation

In SourceWeft

  1. Open Flowcheck in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
