About prism-coder

prism-coder is an MCP server published by the GitHub account dcostenco. Session memory for coding agents: local-first recall, drift detection, on-device inference.

It runs on your own machine: your AI client starts it from the npm package prism-mcp-server at version 20.22.4.

It asks for 3 secrets: BRAVE_API_KEY, GEMINI_API_KEY and SUPABASE_KEY. Give it a key with the least access that still works.

Version 20.22.4 was published on 23 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 5 pass, 3 warn, 0 fail, 1 info. How we check.
