Explore Codebase

This hooks Claude up to code-review-graph's MCP tools to map out your codebase as a queryable graph. You get commands to pull architecture overviews, trace function call chains, search semantically for specific classes, and explore execution flows. It's useful when you're dropped into an unfamiliar repo and need to understand how things connect without grep-and-pray. The workflow pushes you to start with broad stats and community structure before drilling into specifics. With 17.9K stars and passing security audits, it's a solid option if you want structured exploration instead of just reading files sequentially.

Explore Codebase

Use the code-review-graph MCP tools to find your way around the codebase.

Steps

Call get_architecture_overview_tool for the community structure. Call list_communities_tool, then get_community_tool, only for the modules you need.
Call semantic_search_nodes_tool to find a function or class by name or keyword. Pass include_source=True, expand_neighbors=True to get the code of the hits and their direct callers and callees, so you need not open the files. Leave detail_level at its default for this call: minimal drops the source.
Call query_graph_tool with callers_of, callees_of or imports_of to trace relationships. children_of on a file lists its functions and classes, and path_to with to shows how one symbol reaches another.
Call list_flows_tool, then get_flow_tool for one flow, to follow an execution path.
Call find_large_functions_tool to find oversized functions.
Call list_graph_stats_tool only when you need node, edge and language counts.
