Most assistants below ask you to paste this.

2. Add Flash in your AI's settings
Pick the one you use.

Using something else?
Flash is a plain MCP server, so the same address works anywhere MCP does: other assistants, editors, agent frameworks, whatever you build yourself. Paste it wherever that app asks for a custom MCP server, and sign in to Flash when it sends you here.
