About Palace
Palace is a memory layer for AI coding agents that stores decisions, conventions, and fixes locally or on your team's infrastructure. Solo developers can run it free and locally; teams deploy Palace Server to share memory across all developers' agents over MCP, so knowledge flows between team members instead of resetting each session. The system runs entirely on your own infrastructure with no cloud dependencies, supports Cursor, Claude Code, Codex and other MCP-compatible tools, and uses hybrid semantic search with temporal knowledge graphs for recall.

FAQ
- Can I use Palace for free, as a solo developer?
- Yes. palace-rs, the open-source core, is MIT-licensed and free forever. Install it, point Cursor, Claude Code, or Codex at it over MCP, and your agent gets persistent local memory across sessions with no account, cloud, or payment required. Palace Server is only needed when you want to share memory across a team.
- How is Palace Server different from palace-rs?
- palace-rs is a local-first crate for individual developers with memory stored on your machine. Palace Server adds a shared layer: one deployment your whole team connects to, so memory and context flow between teammates. It is built on palace-rs internally.
- Which AI coding tools does Palace support?
- Any tool that supports MCP (Model Context Protocol), including Cursor, Claude Code, Codex, and Claude Desktop. The server exposes all palace_* MCP tools over the network.
- How does licensing work offline or in air-gapped environments?
- Licenses are Ed25519-signed key strings verified locally with no network connection required after you set PALACE_LICENSE_KEY. The signed payload contains your seat count and expiry date and is verified cryptographically on every server start.
