The MCP server is free to use; Polar charges its merchant-of-record fees on real transactions it helps create. A separate sandbox endpoint lets you test with fake money first.

Does it support remote/OAuth?

Yes. It is a hosted remote server at https://mcp.polar.sh/mcp/polar-mcp (with a sandbox variant) authenticated via OAuth, so the first connection triggers a login that scopes the agent to your Polar organization.

Polar MCP server

OfficialPolar186Config last verified Jun 1, 2026

Polar's official remote server lets agents manage products, subscriptions, orders, customers, and revenue metrics on the merchant-of-record platform.

Polar MCP is the official remote server from Polar (polar.sh), a merchant-of-record billing platform for software companies that handles payments, subscriptions, and global sales tax on your behalf. The server exposes Polar's API to AI agents as a curated set of tools: create and update products, list and revoke subscriptions, list orders and generate or fetch their invoices, manage customers by internal or external ID and read their current entitlement state, list payments, and query revenue metrics and limits. That lets an agent run real billing operations or pull live financial state to answer a question end to end.

Because it moves real money, the server is OAuth-authenticated and ships in two flavors: production at https://mcp.polar.sh/mcp/polar-mcp against your live organization, and a separate sandbox at https://mcp.polar.sh/mcp/polar-sandbox for safe testing with fake money. Connect from any client that supports remote MCP, or bridge with the mcp-remote proxy; the first request triggers a login that scopes the agent to your Polar account.

What you can do with it

Manage a SaaS catalog and subscriptions

An agent creates products, updates their benefits, and lists or revokes subscriptions so a maintainer can adjust pricing and entitlements without opening the dashboard.

Answer revenue and billing questions

The agent reads metrics, looks up a customer's state and orders, and fetches an invoice to resolve a billing question end to end.
