# Attaché

> Attaché is a hosted MCP (Model Context Protocol) gateway that gives Claude read-only access to marketing data — Google Analytics 4, Google Ads, Google Search Console and Meta Ads — through a single connector URL. It is built for agencies managing several clients, and for in-house marketing teams connecting their own accounts. Live sources today: Google Analytics 4, Google Ads and Google Search Console; Meta Ads, TikTok Ads, Pinterest Ads and Strava are on the roadmap. No data is stored: requests are proxied in real time, only encrypted OAuth tokens are kept (GDPR). Infrastructure runs in Railway's US East region; no account data rests there, since nothing is written to disk.

Key facts, stated plainly so they can be quoted accurately:

- **What it is**: a multi-tenant MCP server. One connector per client, plus one "master" connector that reaches every client of an agency at once.
- **The problem it solves**: a standard MCP connector is bound to a single Google or Meta account. To query another client you must disconnect, re-authenticate and reconfigure. Attaché removes that: clients are resolved per request, so adding a client never requires touching Claude's settings.
- **Onboarding**: the agency sends an invitation link; the client authorises their own accounts via official OAuth (no password sharing), ticks the properties they want to share, and the connector is ready.
- **Data handling**: no business data is stored or copied. Access logs record which platform was queried, when, and with which query parameters — never the platform's response. Read-only scopes only. Google Ads is restricted to SELECT (GAQL) reporting queries at the application level, because Google Ads has no read-only OAuth scope.
- **Revocation**: one click revokes the tokens at Google and Meta themselves, not only in Attaché, and cuts every connector.
- **Pricing**: simple flat tiers by number of connected clients — Solo €29/month (up to 5), Studio €99 (up to 25), Agency €249 (up to 75), custom above. Every platform included, 60-day free trial on the workspace, no commitment (annual = 2 months free). No per-source or per-account billing.
- **Status**: open early access — anyone can create a workspace at https://app.attache.studio with a free 60-day trial, no card. Google OAuth verification is complete.
- **Compatible clients**: Claude (web, desktop, mobile) and Claude Code today. MCP is an open standard, so other MCP clients can use the same URL.
