Read orders, products, stock and customers; add private comments and change stock in MyCashflow. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the MyCashflow connector, then ask in plain words. The AI picks the tools.
For online store owners and staff who handle orders and stock in MyCashflow.
List the orders by status, then read the shipments of each order to see their status and tracking data.
Find an order by the external id that your marketplace or shop set on it. Then read its products, customer, payments and status.
Find a product by its product code, then read its stock item and the stock changes with their balance change and reason.
List customer accounts filtered by last login date. Customer data is personal data, so read only the accounts you need.
Add a private comment to an order. Only store admins see it, and the customer gets no email.
Changes dataFind the product by its product code and check its stock item. Then add to or subtract from the balance. Each call changes the live stock count.
Changes dataThe login page asks for your Store name, API user name and API key.
Install the API extension under Account → Extensions, then create an API user in the store admin. The API needs the Advanced, Pro or Enterprise plan. Your key is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"mycashflow": {
"url": "https://mycashflow.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"mycashflow": {
"type": "http",
"url": "https://mycashflow.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Store name, API user name and API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this MyCashflow server only. Ask your AI to run mycashflow_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with mycashflow_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with mycashflow_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by MyCashflow. The server calls the MyCashflow API with your own MyCashflow access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Store name, API user name and API key. See Before you connect for where to find them.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Store name, API user name and API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the MyCashflow API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in MyCashflow.
Yes, if you approve it. 2 of the 18 MyCashflow tools can create or change data. The other 16 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this MyCashflow server only. Cancel any time: your paid plan then runs to the end of the paid period. Run mycashflow_usage_status to see how many calls you used.
Ask the AI to run mycashflow_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run mycashflow_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with mycashflow_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
