# Ascend Gateway V5

**One endpoint. 34 MCP tools. 70+ SaaS APIs. Sub-10ms gateway overhead.**

Ascend Gateway V5 is a Cloudflare Worker that authenticates, routes, and proxies API calls to any connected SaaS provider. It supports both **MCP** (Model Context Protocol) for AI agents and **REST** for traditional integrations.

## How it works

```
AI Agent (Claude / Cursor / Gemini / ChatGPT)
               │
               ▼
    Authorization: Bearer {token}
               │
    ┌──────────▼──────────────┐
    │  Cloudflare Worker      │
    │  auth → token → route   │
    │   5ms    2ms    3ms     │
    └──────────┬──────────────┘
               │
