Amazon Q Developer has introduced support for the Model Context Protocol (MCP) in its command line interface (CLI), enabling developers to connect external data sources for more context-aware responses. This enhancement allows access to pre-built integrations and MCP servers, improving code accuracy, data comprehension, unit test generation, database documentation, and query execution without custom integration code. MCP serves as an open protocol that standardizes application integration with large language models (LLMs). Developers can configure MCP servers in a file named mcp.json, which can be stored in the home directory or project root. After implementing MCP, Q Developer can effectively explore database schemas and execute complex SQL queries, significantly enhancing the development experience.
