Connect your repository, get an instant MCP endpoint, and let your AI understand your codebase with compiler-backed precision.
Every pass is deterministic and inspectable. No LLM sits in the extraction path — only compilers, parsers, and the well-typed edges they emit.
Point ArchGraph at a repository. GitHub, GitLab, Bitbucket, or Azure — OAuth only, no agents installed.
Tree-sitter lifts every file into a syntax tree. Classes, methods, imports, interfaces — nothing is guessed.
Language-native compilers resolve call sites, type references, and cross-module bindings into graph edges.
Taint sources, dangerous sinks, and CVE-affected dependencies are annotated on the graph at extraction time.
A secure MCP endpoint ships within seconds. Claude, Cursor, Windsurf, and Cline attach in one line of config.

}A call graph removes matches that live in comments, docs, strings, old deletions, and test fixtures. What you're left with is code that actually runs.
Each language has a dedicated indexer — the compiler toolchain developers already trust — emitting identical graph shape so cross-repo, cross-language queries just work.
Sources, sanitizers, and sinks are annotated on the graph at extraction time — not at query time. Vulnerabilities appear as labeled subgraphs you can ask questions against.
