• get_ai_context

  Primary context tool. Intent-aware (explain/modify/debug/test) with token budgeting.

• get_edit_context

  Everything needed before editing: source + callers + tests + memories + git history

• get_curated_context

  Cross-codebase context for a natural language query ("how does auth work?")

• analyze_impact

  Blast radius prediction — what breaks if you modify, delete, or rename

• analyze_complexity

  Cyclomatic complexity with breakdown (branches, loops, nesting, exceptions, early returns)

• find_circular_deps

  Detect circular import/dependency chains across files

• find_hot_paths

  Most-called functions ranked by transitive caller count

• find_dead_imports

  Find unused imports — modules imported but never referenced

• get_module_summary

  High-level summary of a directory: file count, functions, language breakdown, top complex functions

• search_by_pattern

  Regex search across function bodies, signatures, names, and docstrings

• search_by_error

  Find functions that throw, catch, or handle specific error types

• symbol_search

  Find symbols by name or natural language (hybrid BM25 + semantic search)

• get_detailed_symbol

  Full symbol info: source, callers, callees, complexity

• get_symbol_info

  Quick metadata: signature, visibility, kind

• get_dependency_graph

  File/module import relationships with depth control

• get_call_graph

  Function call chains (callers and callees)

• find_by_imports

  Find files importing a module

• find_by_signature

  Search by param count, return type, modifiers

• find_entry_points

  Main functions, HTTP handlers, CLI commands, event handlers

• find_implementors

  Find all functions registered as ops struct callbacks

• find_related_tests

  Tests that exercise a given function

• traverse_graph

  Custom graph traversal with edge/node type filters

• reindex_workspace

  Full or incremental workspace reindex

• index_files

  Add/update specific files without full reindex

• index_directory

  Add directory to graph alongside existing data

• memory_context

  Get memories relevant to a file/function

• pr_context

  One-call PR review. Runs git diff against base branch, finds changed functions in the graph, reports: blast radius…

• index_markdown

  Index a local .md file (ARCHITECTURE.md, API_DESIGN.md, etc.) into the persistent docs store.

• search_docs

  Semantic search over indexed docs — returns matching sections with heading-path breadcrumbs

• list_doc_sources

  List all indexed source files

• remove_doc_source

  Remove all indexed chunks from a source file

• verify_design

  Cross-reference doc claims vs code graph. direction=forward (doc→code), reverse (code→doc), or both

• design_gaps

  Find identifiers described in docs that don't exist in code yet — build TODO lists from specs

• generate_architecture_doc

  Auto-generate a structured ARCHITECTURE.md from the live code graph (modules, hot paths, complexity, circular deps)

• scan_security

  Security vulnerability scan: 40+ dangerous function patterns, source-to-sink taint tracing, auth coverage for HTTP…

• analyze_coupling

  Module coupling metrics and instability scores

• find_unused_code

  Dead code detection with confidence scoring

• find_duplicates

  Detect duplicate/near-duplicate functions

• cross_project_search

  Search across all indexed projects

• security_control_flow

  Map every execution path through a function — "can this return without hitting the auth check?"

Cross-language code intelligence for AI agents and developers. CodeGraph builds a semantic graph of your codebase — functions, classes, imports, call chains — and exposes it through 42 MCP tools, a VS Code extension, a JetBrains IDE plugin, and a persistent memory layer. Parses 38 languages via tree-sitter. AI agents get structured code understanding instead of grepping through files.
