Available MCP Servers
Catalogue of MCP servers tested with 6022. For how to plug one in, see Configuration.
Production-ready
Stripe
Payment data (customers, invoices, subscriptions, payment intents).
| Field | Value |
|---|---|
| URL | https://mcp.stripe.com |
| Auth | API Key (Bearer) |
| Key | Your Stripe secret key (sk_live_... or sk_test_...) |
Example prompt: "What are the last 5 invoices for customer john@example.com?"
Kirha
Web search, crypto market data, AI research.
| Field | Value |
|---|---|
| URL | https://kirha-mcp-6022.up.railway.app/mcp |
| Auth | Custom Header |
| Header name | x-kirha-api-key |
| Header value | Your Kirha API key |
Tools: websearch, crypto_prices, crypto_analysis. Kirha consumes credits — 500 errors usually mean an empty balance. Contact Kirha or your 6022 administrator for credentials.
Markitdown
Convert documents (PDF, DOCX, XLSX, images) to Markdown text.
| Field | Value |
|---|---|
| URL | https://markitdown-mcp-production.up.railway.app/mcp/ |
| Auth | None |
The URL must end with /mcp/. Without the trailing slash it returns 404.
Tools: convert_url, convert_base64. Scanned PDFs return limited data; very large files may timeout.
Beta / limited
HubSpot
| Field | Value |
|---|---|
| URL | https://app.hubspot.com/mcp/v1/http |
| Auth | API Key (Bearer) |
| Key | HubSpot Private App Token |
In HubSpot's private beta as of late 2025 — you may need to request access. Known to return Invalid tool schema errors on some tools. Rate limiting is aggressive. If it doesn't fit your needs, build a custom HubSpot MCP against their REST API instead.
Notion
The official Notion MCP uses OAuth 2.1, which the 6022 orchestrator doesn't currently support (only static Bearer/Custom Header auth). You have two options:
- Self-host the open-source
notion-mcp-serverand protect it with your own Bearer token. Then add it to the orchestrator as a normal MCP connection. The Notion integration token comes from notion.so/my-integrations — use the "Internal Integration Secret" (ntn_...) and share the pages you want accessible with the integration. - Wait for the orchestrator to add OAuth support.

Need something not on this list?
- Check if the service ships an MCP of its own (many SaaS vendors are adding them).
- Build your own MCP — see Building a Custom MCP Server in the developer docs for the Python/Flask template.
- Contact 6022 support — we may already have something in the works.
