Glossary
What is an MCP server?
The program that exposes an app's actions as tools an agent can call — and how it differs from an API.
Tool calling for AI agents, explained
How an agent actually does things: the call loop, why calls fail, and where tools come from.
OAuth for AI agents
How agents sign in to your apps without your password — scopes, tokens, and who holds them.
What is a hosted app connector?
The service that runs integrations for your agent, so connecting an app is a browser login.
