MCP server exposing NovelAI image generation as tools for AI agents

NovelAI Image MCP

An MCP (Model Context Protocol) server that exposes NovelAI image generation as tools for AI agents (Claude Desktop, Cline, custom agents, remote clients).

Built on the official MCP Python SDK v2 (MCPServer), it lets an agent generate images (txt2img / img2img / inpaint), upscale, run Director tools (line art, emotion, background removal, …), annotate with ControlNet, suggest tags, encode vibes, and query account subscription — all through the standard MCP tool interface.

This package is the server workspace member of the NovelAI-Image-MCP monorepo. The Sphinx documentation site lives at apps/docs/. See the repository root README for the project overview and the docs site for full guides and API reference.

Features

• 11 MCP tools covering the full NovelAI image API surface.
• Transports: stdio (local agents) + streamable-http (remote / multi-client).
• Image return: base64 Image content blocks (the agent sees the image) and PNG saved to disk (path returned as text).
• Async + sync: async tool handlers + a typer CLI for direct invocation.
