Can AI write and deploy Apex code?
Yes. Through an MCP server like ApexGenius, Claude or ChatGPT can inspect authorized project metadata, write staged Apex source, run a validate-only deployment with selected tests, and invoke a full Salesforce Metadata API deployment as a labeled write action.
Scoped Salesforce operations, unlimited ApexGenius tool calls, and an OAuth setup for the selected connection.
The difference from pasting code into a chatbot is context: the AI reads the actual objects, fields, existing classes, and automations in the org, so generated code compiles against reality instead of a guessed schema.
Deploys run through the standard Metadata API with optional test runs. Validate-only and full deploy are separate tools. The AI agent can require confirmation before the deploy write tool is invoked; ApexGenius does not add a universal preview screen. Salesforce applies the permissions of the authorized credential selected for the project.
The same path covers Flows, LWC, validation rules, custom objects, and fields, not just Apex.
