Seosa

If you're building web novel infrastructure with Claude or ChatGPT and need to manage serialized fiction at scale, this gives you structured endpoints for series setup, character databases, episode generation, and quality evaluation workflows. It's Korean-first but the MCP interface is language-agnostic. The remote transport means you don't run anything locally, you just point your client at app.seosa.ink/api/mcp and get access to worldbuilding tools, outline management, and multi-pass editorial feedback loops. Useful if you're prototyping narrative tools or need to maintain consistency across dozens of chapters without rebuilding context each time. The samples show it handles genre conventions (romance, fantasy, wuxia) with attention to pacing and character continuity.
