pip install stablevoyAI assistants (MCP)
The Stablevoy MCP server gives Claude, Cursor and other MCP clients tools to create, check and cancel invoices, read your stores, sum up payments and search these docs, across all of them. Its keys cannot move funds or change any setting.
npx stablevoy-mcp loginFor an assistant that writes your integration, every docs page and guide is also published as Markdown: add .md to the page address without the last slash, for example /docs/webhooks.md. The index of all of them is /llms.txt, rebuilt with every update of this site.
