Understanding Laravel Applications with Neo4j MCP and Graph Intelligence

Modern AI coding assistants are excellent at searching source code, generating code, and answering questions about individual files. However, they often struggle to understand how a large application is actually wired together. Runtime dependency relationships, service container bindings, facades, and architectural connections are difficult to infer through source code search alone.

Neo4j Boost is an open-source Laravel package that combines Neo4j, Laravel Boost, and the Model Context Protocol (MCP) to provide AI assistants with architectural awareness. Instead of relying solely on text-based search, applications can be represented as knowledge graphs, allowing developers and AI tools to explore dependencies, service relationships, and runtime architecture through graph queries.

In this talk, we will explore how Laravel dependency relationships can be exported into Neo4j, how the official Neo4j MCP server integrates with Laravel Boost, and how graph-powered context enables more intelligent debugging, architecture exploration, and developer productivity.

The session demonstrates how service container bindings, dependency injection relationships, facades, and runtime dependencies can be modeled as a graph and queried using Neo4j. Attendees will learn how AI assistants such as Cursor and Claude can leverage graph-backed context to answer architectural questions that are difficult to solve using traditional code search techniques.

We will also discuss the design and implementation of Neo4j Boost, the challenges of integrating MCP with Laravel applications, and practical lessons learned while building an open-source project that combines graph databases, AI tooling, and modern PHP development practices.

The talk includes a live demonstration showing how a Laravel application can be transformed into a navigable knowledge graph and how AI-powered development tools can use this graph to provide deeper architectural insights.
