# Overview

> How to authenticate with the Chainshift Platform API: organization API keys and OAuth 2.1

The Chainshift Platform API supports two authentication methods.

* **[Organization API key](https://dev-docs.trychainshift.ai/en/authentication/api-key.md)**: for servers, scripts, and most MCP clients. This is the simplest option.
* **[OAuth 2.1](https://dev-docs.trychainshift.ai/en/authentication/oauth2.md)**: for browser-based MCP connectors such as Claude.ai and ChatGPT. The connector handles it automatically.

Both methods are ultimately **scoped to an organization**. You can only access data that belongs to the organization the credential was issued for.
