# KRYV-MCP
## Context-as-a-Service — Model Context Protocol Server

> KRYV-MCP is a Remote MCP Server hosted at mcp.kryv.network that bridges any LLM to private data sources using the open Model Context Protocol standard by Anthropic.

## What is KRYV-MCP?
KRYV-MCP is a hosted MCP server. It acts as a secure, authenticated bridge between AI clients and private data sources. Unlike generic LLMs, KRYV-MCP eliminates hallucination by grounding AI responses in real-time private data.

Domain: mcp.kryv.network
Protocol: Model Context Protocol (MCP) v1.0
Transport: Server-Sent Events (SSE) over HTTPS
Stack: TypeScript, Cloudflare Workers, Google Sheets API, Oracle Cloud DB
Security: VIGILIS false-conversation detection layer, OAuth 2.1

## MCP Primitives Implemented

### Tools (Executable Functions)
- vigilis_check(query) — Scans input for phishing/social engineering. Returns { safe, risk_score, recommendation }.
- fetch_context(source, filters?) — Retrieves live data from a registered context source. Returns JSON rows.
- query_sheet(sheet_id, range?) — Reads from a Google Sheet and returns parsed rows.
- list_resources() — Returns all registered context sources.

### Resources (Read-Only Context)
- kryv://sheets/{sheet_id} — Live Google Sheets data
- kryv://sql/{table} — Oracle Cloud SQL table snapshot
- kryv://notion/{page_id} — Notion page content

### Prompts (Templates)
- grounded_answer — Forces AI to cite only data returned by fetch_context.
- vigilis_screen — Pre-screens every user message through VIGILIS before answering.
