witness

Overview

witness is a Model Context Protocol (MCP) server: Distills your sessions or any text corpus into a dated history of how its subject changed. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package @witness-ai/opencode speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.8.0, published under the MIT license, with source at IngTian/witness on GitHub.

You'll find witness in the Memory category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
