Download the Toolkit
Two single-binary tools that work better together. Devscriptor turns your codebase into a local knowledge graph; Juggler is the agent that drives it. No package managers, no build-from-source.
Free forever for personal, non-commercial, and open-source work. Commercial use needs a seat at $19 per developer per month — no license key, nothing to activate. Commercial license · Licensing & terms

Install Devscriptor from the archive
Every archive contains exactly one executable — devscriptor — bundling the CLI, LSP integration, Context Graph, and the unified MCP server. Agents start the server with devscriptor mcp.

Scan your codebase
Fast structural scan — FTS5 keyword search and the entity/relationship graph are ready in seconds. No model loaded.
devscriptor scan ./my-projectAdd semantic search (optional)
Generate vector embeddings once — the model downloads on first run (~150 MB), then unloads. Requires ≥ 4 GB free RAM.
devscriptor embedSet up language servers (optional)
Detect your project’s languages and install the LSP servers it needs via the 4-tier resolution system.

juggler --versionFirst run
Pick a provider and paste a key
init asks which provider you use and which kind of key you hold — a Coding Plan subscription and pay-per-token credits are different keys for different endpoints. It verifies the key before saving anything.
juggler initCheck your setup
doctor reports the resolved endpoint and model, the API key, and every MCP server — including the auto-detected Devscriptor.
juggler doctorRun a prompt, or open the REPL
Headless with -p for scripting and CI; omit it to drop into the interactive REPL. Kimi defaults to kimi-for-coding (K2.7), GLM to glm-5.2.
juggler -p "Explain this repo" --yesInstall Devscriptor first and Juggler finds it automatically — registering all 75 MCP tools on startup, with no configuration. Confirm with juggler doctor.
System requirements
Driven by Devscriptor's optional embedding step. Juggler itself is a lightweight client — it needs only a network path to your model endpoint (or a local one).
100% local & private. Devscriptor's scanning, indexing, and search make no network calls. The only outbound traffic is the one-time embedding-model download (Hugging Face, with the Devscriptor mirror as a fallback) and on-demand LSP server installs — both of which can be pre-staged for fully air-gapped use.
Enjoying the tools?
Free for individuals, and staying that way. If the tools earn a place in your workflow and you'd like to help fund the work, you can chip in — entirely optional, and it unlocks nothing you don't already have. Using them at work? A commercial seat is the part that actually keeps this sustainable.
