# Palace

Local-first memory server for coding agents. It records past decisions, setup choices, and terminal commands in a local SQLite file across sessions.

## What it does

Palace keeps project context intact between agent restarts. Instead of compressing conversations into fuzzy summaries, it stores text verbatim inside a local `palace.db` database. Embeddings run on the local CPU through ONNX Runtime with the `all-MiniLM-L6-v2` model, so no cloud API keys are needed.

The memory layout mirrors a physical building with wings, rooms, and text drawers. When an agent answers a question about historical context, it includes exact citations showing the file and drawer identifier. On the initial search or ingestion run, the binary fetches a 90 MB embedding model into the local cache.

The setup fails on Intel-based Macs because ONNX Runtime builds are unavailable for that target. Palace ships as a compiled Rust binary and works without external vector storage or Docker daemons.

## Requirements
- Needs: a prebuilt binary from the repository releases

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- retrieve architectural decisions made in earlier agent sessions
- keep project coding conventions across fresh tool launches
- avoid re-explaining repository setup rules to the assistant
- trace exact sources and files behind previous technical choices

## Example prompts
- "Why did we drop Redis in favor of SQLite last month?"
- "Search our notes for database migration guidelines."
- "Save our API route naming convention to the project decisions."
