Weavatrix Refactor Js runs on your own machine — the client starts it, so there is no endpoint to ping. 50 installs a week from npm. Last commit 24 Aug 2026.
Transactional refactoring MCP with 11 evidence-backed tools, hash-bound previews, and rollback.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 25 August 2026. No other catalogue keeps this.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This one needs environment variables set before it will start:
WEAVATRIX_ALLOW_SOURCE_EDITS (Set to 1 to authorize apply_edit_plan and rollback to write source files; unset, the refactor tools stay preview-only), WEAVATRIX_REFACTOR_HOME (Optional directory for the rollback snapshot store; defaults to a per-repo location), WEAVATRIX_PRECISION (Core semantic precision: lsp (default) or off).
The author declared them in the registry entry; get the values from the project itself.
