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 FastMCP 4 (the fastmcp framework over the MCP SDK v2 mcp>=2.0.0), 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.
- 2 prompts + 3 resources + 1 resource template: prompt templates for drafting and tool
sequencing, plus
novelai://models,novelai://samplers,novelai://defaultsandnovelai://outputs/{name}. - Transports: stdio (local agents) + HTTP (remote / multi-client), the
latter optionally protected by
MCP_AUTH_TOKEN. - Image return: base64
Imagecontent blocks (the agent sees the image) and PNG saved to disk (path returned as text). - Async + sync: async tool handlers + a
typerCLI for direct invocation.
Install
pip install novelai-image-mcp
Quick start
# 1. Configure credentials
export NOVELAI_TOKEN=pst-... # from https://novelai.net > Account
# 2. Run (stdio — for local agents)
novelai-image-mcp serve
# 3. Or over HTTP
MCP_TRANSPORT=http novelai-image-mcp serve
# → http://127.0.0.1:8000/mcp
Agent skills
Three skills.sh packages (novelai-cli,
novelai-mcp-tools, novelai-workflows) teach AI agents how to drive the
CLI and MCP tools:
