Every protocol exposes the same actions and uses the same two values: your API key and the account’s x-account-id. The full guides live under Call Actions:

Agent SDK

Typed TypeScript and Python tools for your agent framework. Fetch, filter, and execute.

MCP

Call the MCP server from your own product or agent framework with an API key and account ID.

Agent2Agent

Call a pre-built agent per integration, for multi-agent orchestration.

RPC/HTTP

Call an action from any backend or script with no agent or framework.
To connect ChatGPT, Claude, Cursor, or another AI platform without writing code, use the StackOne MCP server through AI Platforms instead. Each user signs in with OAuth, so no API key is involved.
