What you are opening

Local-first code, document and log search with lexical and vector retrieval, exposed to coding agents through MCP.

How to set it up

Read the pinned README, license and companion scripts.
Choose a documented setup below; review dependencies and any configuration changes before running it.
Try one small task in a test workspace and review the result.

Requirements and third-party terms

Install and review the XERJ binary first, then start a local node. Replace absolute paths; the README marks these client configurations untested. Keep the insecure development node private.

Before you add it

Read the instructions and review any scripts before running them.
Check tool access, required credentials and third-party network requests.
The source license and any resource-specific terms take precedence.
