Prism Coder
Give your AI agent memory that lasts. Persistent sessions, knowledge graphs, and offline tool-routing — fully local and free.
Prism Coder is an MCP server that gives Claude, Cursor, and other AI tools long-term memory that survives across sessions. It ships with the open-weight prism-coder model fleet (2B–27B) for fast, offline tool-routing — no cloud required.
No account needed. No API keys. Runs on your machine.
A paid subscription adds cloud sync, higher model tiers, and team features through the Synalux portal.
Quickstart
The free tier needs no account, no API key, and no cloud. Add the server to your MCP client:
{
"mcpServers": {
"prism": {
"command": "npx",
"args": ["-y", "prism-mcp-server"]
}
}
}Open Claude Desktop or Cursor and your agent now has memory backed by a local SQLite database (~/.prism-mcp/data.db).
Optional — local model fleet for offline tool-routing. Pull whichever fits your hardware:
