NabChan MCP Server

What it does

NabChan MCP Server provides a dedicated interface for AI models to query, search, and read the official Nablarch documentation. It uses a high-performance backend powered by DuckDB with full-text search and Lindera for Japanese morphological analysis, ensuring accurate retrieval of framework-specific technical data.

Tools

• search_document: Searches the Nablarch documentation and returns titles, URLs, and summaries.
• read_document: Fetches the content of a specific Nablarch document and converts it to markdown for the AI.
