This MCP server provides access to SaaSus Platform documentation through three specialized tools for searching, content retrieval, and sitemap navigation. Built by Anti-Pattern Inc. using TypeScript with Japanese language support via Lunr.js, it enables AI assistants to search the SaaSus docs index, fetch full article content with HTML-to-Markdown conversion, and explore the complete documentation structure through sitemap parsing. The implementation includes security restrictions to only access SaaSus documentation URLs and optimized content extraction that removes navigation elements while preserving article structure, making it valuable for developers and users seeking programmatic access to SaaSus Platform documentation and support workflows.

A visual Retrieval-Augmented Generation MCP server that renders web pages, PDFs, and design screenshots into visual tiles and enables natural language querying over them via multimodal vision embeddings.

Enables LLMs to use llama.cpp models via MCP protocol by bridging MCP requests to an OpenAI-compatible API.
