How do I find my HelloAsso API credentials?

Log in to your HelloAsso account, go to **Mon Compte > Integrations & API**. You can generate your **Client ID** and **Client Secret** from the API section there.

What is an organization 'slug'?

The slug is the unique textual identifier for your association (e.g., in `helloasso.com/associations/my-asso`, the slug is `my-asso`). You can find it by using the `list_my_organizations` tool.

Can I generate a payment link directly from the AI agent?

Yes! Use the `create_checkout_intent` action. You must provide the association slug and a JSON string with the amount (in cents) and return URL. The agent will return a redirect link for the user.

Is the integration secure for association data?

Absolutely. The integration uses industry-standard OAuth 2.0 Client Credentials over HTTPS. Your credentials are encrypted and stored securely within the Vinkius Cloud infrastructure.

HelloAsso + Claude Desktop FAQ

Common questions about integrating HelloAsso 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.
