MCP overview - ElarisLabs

Connect ElarisLabs Creative Studio to Claude, Cursor, and other MCP clients. Generate images, video, audio, brand packs, captions, and composer edits from any agent that speaks MCP. Credits bill to the brand your API key is bound to.

What is MCP?

The Model Context Protocol (MCP) is an open standard for connecting AI assistants to external tools and data. Instead of copy-pasting API docs into a chat, the client discovers callable tools from a server. The model invokes them when your prompt needs real actions, like generating an image, listing projects, or resizing a brand pack.

You (prompt) -> MCP client (Claude, Cursor) -> ElarisLabs MCP (/api/mcp) -> Creative Studio (models + credits)

Tools, not chat plugins

The agent sees structured tools with schemas. It picks the right one and passes arguments. No manual API calls.

Remote HTTP

ElarisLabs runs a hosted MCP endpoint. No local install required. Just paste a JSON config and your API key.

Brand-scoped billing

Every key is bound to one brand. Generation tools deduct credits from that brand’s balance. Discovery tools are free.

How does the connection work?

Create a brand-bound API key with an expiry and spend cap
Point your MCP client at https://studio.elarislabs.ai/api/mcp with that key
Call discovery tools (free), then generation tools (credits)
