+## code-review-graph
+
+Structural code intelligence MCP server by tirth8205. Parses source code with Tree-sitter AST into a knowledge graph (functions, classes, imports, calls, inheritance, tests). Stored in SQLite. 28+ MCP tools for token-efficient code review, blast-radius analysis, and architectural insights. **Per-project** — each repo gets its own `.code-review-graph/graph.db`.
+
+**Install:**
+```bash
+uv tool install code-review-graph  # or: pipx install code-review-graph
+```
+Installed to `~/.local/bin/code-review-graph` v2.3.7.
+
+**Build a graph for a project:**
+```bash
+cd /etc/nixos
+code-review-graph build    # parses codebase → .code-review-graph/graph.db
+```
+
+**Key MCP tools:**
+| Tool | What it does |
+|------|-------------|
+| `get_review_context` | Compact review context (callers, callees, tests, risks) |
+| `get_impact_radius` | Blast radius — every caller/dependent/test affected by a change |
+| `query_graph` | Direct graph queries (traverse call chains, dependency paths) |
+| `semantic_search_nodes` | Semantic (embedding-based) code search |
+| `detect_changes` | Diff analysis: what changed and what's affected |
+| `traverse_graph` | Walk the graph in any direction (BFS/DFS from any node) |
+| `get_architecture_overview` | High-level structure: packages, clusters, entry points |
+| `get_affected_flows` | Execution paths impacted by a change |
+
+**Complement to codebase-memory-mcp:** code-review-graph captures **what your code is** (structure, dependencies), codebase-memory-mcp captures **what agents learn** (decisions, patterns, runbooks). They solve different layers — install both.
+
+**Installed on:** .27 (uv tool install), .51 (nix-shell -p uv → uv tool install)
