What does Slash do?

Slash is a financial platform that lets AI agents perform banking tasks. It provides a secure bridge, using the Model Context Protocol (MCP), so agents can directly interact with Slash's API. This means an AI can create a new company credit card, set a monthly spending limit on it, or send a payment to a vendor, all without a human needing to log into a dashboard. The core idea is to move financial operations from manual clicks to automated, agent-driven commands.

How it works is straightforward. You connect your MCP-compatible AI agent (like Claude or a custom build) to Slash's MCP server. The agent then has three main tools: it can discover all available Slash API endpoints, inspect the details of any endpoint, and finally call those endpoints to execute actions. Security is a major focus. Card numbers and CVVs are encrypted with your RSA public key before an agent ever sees them, and you can use read-only API keys to force a human to approve any spending action before it goes through.

This tool is for businesses that are already using or building AI agents and want to give them safe, controlled access to financial functions. It turns an AI assistant from a conversational tool into an operational one, capable of handling repetitive tasks like provisioning cards for new employees, adjusting department budgets on the fly, or processing batch payments. It combines the speed of AI with the necessary guardrails for moving money.
