Kora MCP Server

The Deterministic Authorization Gate for AI Agents

Kora provides a cryptographically secure Go/No-Go layer for autonomous software. This Model Context Protocol (MCP) server enables LLMs (Claude, GPT-4, Cursor) to request explicit permission before initiating financial actions.

How it works

Claude says "I need to spend $50 on AWS" → MCP server signs the request with Ed25519 → sends to Kora → 14-step deterministic pipeline → APPROVED or DENIED with actionable hint.

Every decision is cryptographically sealed. No ML. No guessing.
