01
Impact
Find direct and transitive dependents, cycles, risk hotspots, and likely test surface before a change.
Local-first code intelligence for Cursor
Know what breaks before your coding agent changes it.
LunaForge maps real dependencies, predicts change impact, correlates regressions, checks architecture policy, and creates evidence before an AI agent edits shared code.
No account · No API key · TypeScript, JavaScript, and Python · Source stays local
Developer prompt
“Add partial refunds to the payment service. Do not edit until you know the blast radius.”

One intelligence layer
Built for the moment before an agent acts.
Not another autocomplete tool. LunaForge supplies repository truth to Cursor and other MCP-capable agents.
02
Autopsy
Combine stack traces, Git history, and dependency paths to rank the most likely regression sources.
03
Guardian
Express architecture boundaries as rules and block unsafe agent plans with explainable evidence.
04
TimeTravel
Trace churn, ownership, previous breakages, and relevant commits around the code being changed.
05
CodeFlow
Follow dependency paths through unfamiliar repositories without uploading source to a cloud service.
06
Receipts
Create a digest-backed record of affected code, policy decisions, required checks, and final validation.
Safe change workflow
Understand. Decide. Change. Prove.
Index
Build a local graph from supported repository imports.
Analyze
Calculate blast radius, history, cycles, and ownership.
Govern
Apply Guardian rules and require approval when risk is high.
Evidence
Export a machine-readable receipt for review and CI.
Free local preview
Reach the first answer in under two minutes.
Install the local MCP engine and Cursor plugin with one command. The preview requires Node.js 20+.
Trust by construction
Local source analysis, explicit limitations.
The free engine reads supported files on your machine. The preview does not claim whole-program semantic analysis, certification, or perfect dependency resolution.
