Manual without Smithery

Its much easier to visit the above Smithery link and just copy the correct command, but if you are more daring, here’s the manual steps:

• Claude:

1. git clone this repo
2. Run bun install in the folder to install dependencies
3. Copy the absolute path to “index.ts”
4. Add the following to your claude_desktop_config.json or equivalent to your AI app:

{
	"mcpServers": {
        // ...
		"autumn": {
			"command": "bun",
			"args": [
				"run",
				"{YOUR ABSOLUTE PATH TO index.ts}",
				"--apiKey="{YOUR API KEY}""
			]
		}
	}
}

• Any other app:

If you want to run manually, you must have Bun installed to run this MCP server. Here’s the command for other apps that support commands instead:

bun run {absolute path to index.ts} --apiKey="{your api key}"

You may use either your public or secret key, but some features may not be accessible using the public key.
