Run a company’s money from code.

Capxul is the SDK, CLI and MCP server for company payments in stablecoins. The company’s Owners approve every change, and the money stays in the company’s own account.

For developers

Build with the SDK

A typed TypeScript client for your backend, plus React hooks for your UI.

npm install @capxul/sdk

Quickstart →

For operators and scripts

Run it from the terminal

Run SDK operations as commands, with --json output for scripts and CI.

npm install -g @capxul/cli

For agents
