Prism MCP

Prism is a local-first software intelligence system for coding agents that provides repository analysis including file preparation, code matching, blast radius calculation, and code review. It runs entirely on the user's machine without external models or telemetry, offering 21 MCP tools to help agents write better code by preparing changes, reviewing diffs, and ensuring house style compliance.
