What is the Polar MCP Server?

Connect your Polar account to any AI agent and take full control of your digital commerce operations through natural conversation.

What you can do

  • Product Management — List, retrieve and audit all products (one-time, subscription, free) with pricing and metadata
  • Subscription Tracking — Monitor active, canceled and past_due subscriptions with billing periods and customer info
  • Order & Revenue — List completed orders with amounts, currency, payment status and customer details
  • Customer Discovery — Browse customers by email, name and purchase history
  • Discount Management — List, create and audit discount codes with percentage or fixed-amount types
  • Checkout Operations — Create checkout sessions for products and track open, expired and confirmed checkouts
  • Webhook Audit — Review configured webhook endpoints and their subscribed events

How it works

  1. Subscribe to this server
  2. Enter your Polar Personal Access Token
  3. Start managing your commerce from Claude, Cursor, or any MCP-compatible client

No more clicking through the Polar dashboard to check subscriptions or create discount codes. Your AI acts as a dedicated commerce engineer.

Who is this for?

  • Indie Developers — quickly check subscription status, review orders and create discount codes without leaving your IDE
  • Commerce Teams — audit product catalog, track revenue via orders and manage customer data
  • Marketing — create promotional discounts, track checkout conversion and review webhook integrations

Why CrewAI?

When paired with CrewAI, Polar becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Polar tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

  • Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools

  • CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the mcps parameter and agents auto-discover every available tool at runtime

  • Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls

  • Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

FAQ

Frequently asked questions

01

How do I create a Polar Personal Access Token?

Log in to the Polar Dashboard, go to Settings > Developer > Personal Access Tokens, click Create Token, give it a name and copy the token immediately — it starts with polar_pat_ and won't be shown again.

02

Can I create discount codes via the agent?

Yes! Use the create_discount tool with a name, code, type (percentage or fixed_amount) and amount. Optionally set the duration (once, forever, repeating). The discount will be available during checkout.

03

Can I check my subscription revenue?

Yes! Use list_subscriptions with status 'active' to see all active subscriptions, and list_orders to see completed orders with their amounts. Combine both to get a full picture of your recurring and one-time revenue.

04

Can I create checkout links programmatically?

Yes! Use create_checkout with a product_id and optionally a customer_id and discount_id. This creates a checkout session that returns a URL you can share with customers or embed in your app.

05

How does CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

06

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

07

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

08

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

09

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.

10

MCP tools not discovered

Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.

11

Agent not using tools

Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".

12

Timeout errors

CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.

13

Rate limiting or 429 errors

Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
