Droste

<!-- mcp-name: io.github.lorismascio17/droste-memory -->

See your codebase as a living galaxy — and give your agents causal memory of it.

Droste indexes any repo into a fractal, zoomable map of its symbols, wires them together with their real call / import / DB edges across languages, and serves an agent the causal slice of code it actually needs — not just keyword matches.

Local-first · zero-config · polyglot · MCP-native

Zooming out reveals the causal web — every cyan arc is a real syntaxdependency edge. Full flythrough (FastAPI)*

Quickstart

# Windows
python -m pip install --upgrade droste-memory

# macOS / Linux
python3 -m pip install --upgrade droste-memory

droste index . # index the current repo
droste view    # open the fractal galaxy in your browser

Install once, then index and view. droste view opens a full-screen, 60fps zoomable map of your code — scroll to dive from the project star into folder orbits, down to the individual functions, with the causal edges glowing between them.

Need it for an agent instead of your eyes?

droste context "checkout flow" --budget 1500   # causal context slice for an LLM

Running droste with no arguments prints the command palette:

Why it's different

Most "code context" tools rank by keyword (ctags / ripgrep / repo-maps) or by embedding cosine (vector-RAG). Both can only return what resembles your query. A caller that shares no tokens — or a database function in a different language — is invisible to them, yet it's exactly what you need to understand or change the code.

Droste's edge is the causal graph:
