find_dead_imports
Find unused imports — modules imported but never referenced
How to use it
find_dead_imports is exposed by the CodeGraph MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the find_dead_imports tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.

npx @vscode/vsce package # VSIXOther tools in CodeGraph (39)
Cyclomatic complexity with breakdown (branches, loops, nesting, exceptions, early returns)
Module coupling metrics and instability scores
Blast radius prediction — what breaks if you modify, delete, or rename
8 — search + symbol info + AI context
Find identifiers described in docs that don't exist in code yet — build TODO lists from specs
Find files importing a module
Search by param count, return type, modifiers
Detect circular import/dependency chains across files
Main functions, HTTP handlers, CLI commands, event handlers
Most-called functions ranked by transitive caller count
Find all functions registered as ops struct callbacks
Tests that exercise a given function
Auto-generate a structured ARCHITECTURE.md from the live code graph (modules, hot paths, complexity, circular deps)
Primary context tool. Intent-aware (explain/modify/debug/test) with token budgeting. Returns source, related symbols, imports, siblings, debug hints.
Function call chains (callers and callees)
Cross-codebase context for a natural language query ("how does auth work?")
File/module import relationships with depth control
Full symbol info: source, callers, callees, complexity
Everything needed before editing: source + callers + tests + memories + git history
High-level summary of a directory: file count, functions, language breakdown, top complex functions
Quick metadata: signature, visibility, kind
17 — callers/callees/deps/impact/traverse/PR context
Add directory to graph alongside existing data
Add/update specific files without full reindex
Index a local .md file (ARCHITECTURE.md, APIDESIGN.md, etc.) into the persistent docs store. Heading-tree chunking with leaf-node embeddings.
List all indexed source files
14 — codegraphmemory plus the docs tools
Get memories relevant to a file/function
One-call PR review. Runs git diff against base branch, finds changed functions in the graph, reports: blast radius (callers), test coverage + gaps, affected modules, diff-aware change classification (signature vs body), stale-doc warnings, complexity, commit-message hint, suggested reviewers from gi
Full or incremental workspace reindex
Remove all indexed chunks from a source file
Security vulnerability scan: 40+ dangerous function patterns, source-to-sink taint tracing, auth coverage for HTTP endpoints (7 languages/frameworks), architectural layer violations, weak crypto, hardcoded secrets
Find functions that throw, catch, or handle specific error types
Regex search across function bodies, signatures, names, and docstrings
Semantic search over indexed docs — returns matching sections with heading-path breadcrumbs
pro security tools only (empty on community)
Find symbols by name or natural language (hybrid BM25 + semantic search)
Custom graph traversal with edge/node type filters
Cross-reference doc claims vs code graph. direction=forward (doc→code), reverse (code→doc), or both
