Ask your AI assistant to check your 550W AI credit balance, then show your recent media processing tasks. Processing tasks use your account credits at the current website prices.

If the email link opens in another browser, return to the original authorization tab. If the request expires, reconnect from your MCP client.

Install the Skill

Use ClawHub with OpenClaw, or download the ZIP for a compatible local Agent Skills client. It includes a local Node.js MCP server. MCP does not grant file or network access by itself; configure the client and allow only access you authorize.

Dify · API API

A hosted agent can connect only if that specific product supports remote MCP and browser OAuth and its settings allow this endpoint. 550W connectivity is not verified for every hosted client; follow the product’s current setup instructions. Otherwise, use a supported Developer API integration. OAuth uses your 550W account; API integrations use separate API credentials.
