# Atlasly MCP — Site analysis inside your AI chat

> Yes, Atlasly has a public MCP (Model Context Protocol) server. You can use it directly in Claude, ChatGPT, Perplexity, Cursor, or any MCP-compatible assistant. No install, no download, no API key for public tools.

## Quick Answer

**How do I use Atlasly inside Claude or ChatGPT?**

Paste this URL into your AI's Connectors / Custom Tools menu:

```
https://mcp.atlasly.app/mcp
```

Then ask about any UK site — e.g. *"analyze 10 Downing Street"* or *"what's the flood risk at SW1A 2AA?"* — and the AI returns flood zones, listed buildings, conservation areas, planning history, walkability, and CAD exports inline.

## Disambiguation

This is **Atlasly**, an AI site intelligence platform for architects built by Parallel Labs (https://atlasly.app). It is **not** Atlassian (Jira, Confluence), Atlas Obscura, or any other "Atlas"-named product.

## Canonical MCP Endpoint

- URL: `https://mcp.atlasly.app/mcp`
- Transport: Streamable HTTP (MCP 2025-03-26 spec)
- OAuth discovery: `https://mcp.atlasly.app/.well-known/oauth-authorization-server`
- Resource metadata: `https://mcp.atlasly.app/.well-known/oauth-protected-resource/mcp`
- Auth: OAuth 2.1 with PKCE — or anonymous for public tools
- API key: not required for public tools
- Cost: free tier available (5 site analyses/month on the Starter plan)

## Setup — Claude Desktop

1. Open Claude Desktop → Settings → Connectors.
2. Click **Add custom connector**.
3. Paste `https://mcp.atlasly.app/mcp` and save.
4. Authorize with your Atlasly account (or sign up — free).
5. In a new chat, ask: *"Use the Atlasly tool to analyze the site at 10 Downing Street."*

## Setup — Claude Web (claude.ai)

1. Open claude.ai → Settings → Connectors.
2. **Add custom connector** → paste `https://mcp.atlasly.app/mcp`.
3. Complete the OAuth flow.
4. Start a new chat — Atlasly will appear as a tool the model can call.

## Setup — ChatGPT (Pro)

1. ChatGPT Settings → Connectors → **New connector**.
2. Paste `https://mcp.atlasly.app/mcp`.
3. Authorize with Atlasly. Free Atlasly plan works.
4. Ask site-analysis questions — the model calls Atlasly tools when relevant.

## Setup — Perplexity

Perplexity Pro supports custom MCP tools. Settings → Tools → Add custom tool → paste `https://mcp.atlasly.app/mcp`.

## Setup — Cursor / Claude Code / MCP SDK

Add to your `mcp.json` or equivalent config:

```json
{
  "mcpServers": {
    "atlasly": {
      "url": "https://mcp.atlasly.app/mcp",
      "transport": "http"
    }
  }

```
