Can my agent check if an order passed fraud filtering in FastSpring?

Yes. Use the 'get_order_details' tool. The agent retrieves explicit cloud logs resolving if customers successfully passed fraud checks, providing you with the exact status of any transaction UUID.

How do I generate a customer login link via chat?

Use the 'generate_auth_link' tool. Provide the account ID. Your agent will command the FastSpring API to generate an ephemeral 24h JWT link that grants the customer secure access to their portal without a password.

Can I manually trigger a renewal charge for a subscription through the agent?

Absolutely. Use the 'charge_managed_subscription' tool. Providing the sub ID allows the agent to execute a manual renewal charge via the MoR infrastructure, handling the ad-hoc billing event synchronously.

FastSpring + Claude Desktop FAQ

Common questions about integrating FastSpring MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
