Occasio MCP Server

Occasio is a local proxy that sits between your AI coding agent (Claude Code, Cline, or anything that talks to the Anthropic API) and whichever LLM endpoint you configured. Every tool call passes through one human-readable policy file you control. You can see what is leaving your machine in real time, block what should not happen, and end up with a tamper-evident hash-chained log that a third party can verify…

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
