What is MCP?

Model Context Protocol (MCP) is an open standard that lets AI assistants securely connect to external data sources. Instead of copying data into prompts, MCP lets AI query your tools directly — databases, search engines, web pages, and more.

On-demand access

AI fetches data only when needed for your question

Secure by design

Your credentials stay protected, permissions enforced

Natural language queries

Ask in plain English, get structured answers

AI Chat in Commander

You: What did we invoice last month?

AI: [Querying your Stripe connection...]

AI: Here is last month by status, from Stripe:

• Paid, open and overdue invoices, with totals

• The customers behind the overdue ones

Ready-made MCP sources

Connect one of these in Commander Connections and One can query it in AI Chat. Each reads through your own connection, so One sees only the account you connected.
