AI-assisted software development with Amazon Q Developer
"When I reviewed Amazon Q Developer in 2024, I noted that it was able to generate whole functions in common programming languages with only a few fixes. It was useful for completing lines of code, doc strings, and if/for/while/try code blocks as you type. It could also scan for vulnerabilities and help you fix code problems. However, it could not generate full functions for some use cases, but instead reverted to line-by-line suggestions."
"Some of the current differentiators for coding agents are their ability to call tools (e.g. read files, run applications, show edit diffs, and understand Git and GitHub) and their ability to define and use Model Context Protocol (MCP) servers. MCP servers are tools that allow AI models to interact with external services, such as databases, APIs, and enterprise systems, using a standard, unified protocol. Another differentiator is the ability to run tools and projects in an isolated environment."
Amazon Q Developer is an AI-powered coding assistant with chat, CLI, Model Context Protocol (MCP) and agent support, and AWS expertise. The assistant can generate whole functions in common languages with minimal fixes, complete lines, docstrings, and control-flow blocks, and scan for vulnerabilities to suggest fixes. Some scenarios fall back to line-by-line suggestions rather than full-function generation. The platform moved from Amazon Bedrock/AWS-specific training toward offering Claude Sonnet model choices including 4.5. Difficulty ranges from trivial line completions to moderately hard application generation and challenging large-repo bug fixes. Tool and MCP support exist but configuration is harder than necessary, and isolated cloud environments are not optimally implemented.
