Integrations, connectors and the MCP server

Polymet connects to other tools in four ways. They sound alike and do different jobs. This page tells them apart.

The four at a glance

	What it is	Who sets it up	Applies to	Example
Integrations	Your own GitHub and Figma accounts, connected to Polymet	You, once	Every project you work on	Connect your GitHub account so you can import a repository
Agent connectors	Tools the agent can call while it generates	You, once per tool	Your generations, in any project	Let the agent read a Linear issue or a Notion page
Project integrations	Services one project uses	Someone on the project, per project	That project only	A project’s Backend, its GitHub repository, its custom domain
Polymet MCP server	Polymet, used from another AI tool	You, in that tool	Your coding agent	Ask Claude Code to create a Polymet project and read its code

Which one do I need?

I want to	Use	Page
Import a repository or a Figma file	Integrations	Connect GitHub, Import from Figma
Have the agent look something up in Linear, Notion, Slack or Sentry	Agent connectors	Agent connectors
Give my app a database, sign-in and file storage	Project integrations: Backend	Add a backend
Keep a project’s code in a GitHub repository	Project integrations: GitHub repository	Sync a project with a repository
Serve my app from my own domain	Project integrations: custom domain	Use your own domain
Work on Polymet projects from Claude Code or Cursor	Polymet MCP server	Use Polymet from your coding agent

Three things that are easy to mix up

GitHub shows up twice. First you connect your GitHub account, which is an integration. Then you link a project to a repository, which is a project integration. You connect the account once and link each project separately. Agent connectors and the Polymet MCP server point in opposite directions. With an agent connector, Polymet’s agent reaches out to another tool. With the Polymet MCP server, another tool’s agent reaches into Polymet. Agent connectors are yours, not the project’s. A connector you set up is used by your generations only. A teammate working in the same project needs to connect their own.

The words

You connect an account or an agent connector.
You link a project to a repository or to a design system, and unlink it later.
You enable a project’s Backend.
