Use Casii MCP in Cherry Studio

Prerequisites

1. Cherry Studio installed and signed in.
2. An API key created in the dashboard — the MCP URL is already filled into the quick reference below.

Open API Keys

Connection quick reference

The quick reference already contains your MCP URL; just replace YOUR_API_KEY with your key, then paste into Cherry Studio.

{
  "mcpServers": {
    "casii": {
      "type": "streamableHttp",
      "url": "https://api.casii.io/mcp/",
      "name": "Casii MCP",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Keys in the screenshots are masked — use your own API key when you set things up.

Setup steps

1. 1

   Open Cherry Studio and click the gear icon in the bottom-left corner to open Settings.

   
2. 2

   In the Settings sidebar, click "MCP" under Tools, then click "+ Add" in the top-right corner.

   
3. 3

   Choose "Quick create" from the menu.

   
4. 4

   Paste the MCP URL from the quick reference below into "URL" (keep the trailing slash). In "Headers", enter Authorization=Bearer YOUR_API_KEY (one space between Bearer and the key), then click "Save" in the bottom-right.

   
5. 5

   Scroll up and check that Name is Casii and Type is "Streamable HTTP (streamableHttp)". Turn on the switch in the top-right — when "Connected" appears next to the name and the Tools tab shows a count, the connection works.

   
6. 6

   Go back to the chat page and confirm Casii shows as "Connected" in the MCP list above the input box.

   
7. 7

   Type your export request in plain language (you can copy the example below). The first time the AI calls a Casii tool, a confirmation appears — click "Allow".

   
8. 8

   Wait for the AI to finish. The reply lists the row count, credits charged and a CSV download link — click it to download. For Excel, change format=csv at the end of the link to format=xlsx.

   

Verify it works

Ask for an export directly in Cherry Studio, e.g.:

The first call asks for tool permission; after that the AI handles detection, quoting and creation automatically. Creating and resuming must carry a stable idempotency key (idempotency_key, UUID format) generated once: retrying with the same key and the same parameters returns the original tasks and never charges twice; only changed parameters make it a new operation with a new key.
