Durable, hierarchical, repo-scoped memory for Claude Code. Local-first MCP server with hybrid lexical + vector retrieval over your codebase, docs, and accumulated decisions.

claude-repo-mem

Durable, hierarchical, repo-scoped memory for Claude Code. Local-first MCP server.

claude-repo-mem indexes your repository — code, docs, and your own accumulated decisions — into a SQLite database with hybrid lexical + vector retrieval, then exposes it to Claude Code as 11 MCP tools.

---

Install

pip install claude-repo-mem

Requires Python 3.11+.

---

Quick start

cd your-repo
claude-repo-mem index               # build the index (downloads bge-small on first run, ~90MB)
claude-repo-mem doctor              # verify: units, by_layer, T2 coverage, counters

To expose it to Claude Code, drop a .mcp.json in your repo root:

{
  "mcpServers": {
    "claude-repo-mem": {
      "command": "claude-repo-mem",
      "args": ["serve", "--watch"]
    }
  }
}

Claude Code will auto-launch the server on workspace load. The --watch flag runs an incremental file watcher (debounced 750ms) so the index stays current as you edit.

Prefer not to run the watcher? Install a git hook instead:

claude-repo-mem install-hooks       # writes .git/hooks/post-commit

---

CLI

claude-repo-mem index [--embedder NAME] [--no-embed] [--reset]
claude-repo-mem serve [--watch | --no-watch]
claude-repo-mem doctor                              # layer counts, T2 coverage, counters
claude-repo-mem install-hooks [--force]             # git post-commit reindex
claude-repo-mem distill [--yes] [--transcript PATH] # extract durable memories from a transcript
claude-repo-mem bench   --fixture queries.yaml [--k 5] [--no-embed]

Languages and synthesizers

Language	Parser	Notes
Python	tree-sitter	classes, methods, functions, docstrings
JavaScript / TypeScript	tree-sitter	functions, classes, methods, JSX
Java	tree-sitter	classes, interfaces, methods, constructors
Go	tree-sitter	funcs, methods, structs, interfaces
Rust	tree-sitter	fn, impl methods, structs, traits
Markdown	markdown-it	sections by heading hierarchy

Synthesizers add cross-file edges on top of parser output:

• Flask @app.route(...) → handler.
• Django path(...) / re_path(...) → handler (resolves dotted refs against views.py).
• Express app.METHOD(url, handler) → same-file handler.
• Python imports → cross-module edges.
• React hooks — useState setter calls emit mutates_state_of edges on the containing component.
