Quickstart
Sign in, create a workspace, connect your first tool, then point Claude or another MCP client at the gateway and call it, all in about five minutes.
By the end of this you will have one tool connected and Claude calling it.
Sign in and claim your organization
Go to app.popmcp.com and sign in with Google.
The first person from a company domain to sign in creates that domain's organization and becomes its owner. Later sign-ins from the same domain need an invite. Personal addresses such as Gmail and Outlook each get their own organization.
Create a workspace
A workspace holds at most one connection per provider. Most teams start with one workspace per client or per brand.
Connect a tool
Open the marketplace, pick a connector, and follow its setup page in these docs. Each one walks through obtaining the credential for that specific provider.
KlaviyoConnect Klaviyo to manage profiles and segments, run email and SMS campaigns and flows, and track customer events.API key
ShopifyConnect Shopify to manage orders, products, customers, inventory, and fulfillment across your store.OAuth
StripeConnect Stripe to manage charges, payments, customers, subscriptions, invoices, refunds, and payouts.API key
NotionConnect Notion to create and update pages, query and build databases, edit block content, and search your workspace.API keyPopMCP verifies the credential against the provider immediately. On success the connection shows Verified and its tools are provisioned.
Point your AI client at the gateway
Add PopMCP as a remote MCP server:
https://app.popmcp.com/mcpYour client discovers the OAuth endpoints, registers itself, and opens a consent screen. Tick the connectors you want this client to reach, then approve.
See Choosing an AI client for per-client setup.
Call a tool
Ask your client something that needs the tool. For a Klaviyo connection:
"List my Klaviyo segments and tell me which has the most members."
The client calls list_connections to see what it has, then the Klaviyo toolset.
On paid plans, connected tools can perform writes, and a write runs as soon as your agent calls it. Grant each client only the connectors it needs. On Scale and Enterprise, keep teammates on read-only until you trust what their agents do. See Access modes.
Introduction
PopMCP turns the SaaS you pay for into MCP tools behind one OAuth-protected URL, keeps credentials server-side, and re-checks access on every call.
Connect your first integration
What connector setups share and where they differ: an API key or an OAuth app, the exact callback URL, verification, and the account picker.
