What is the Genji MCP server?

Genji mcp server lets Claude, Cursor and other MCP clients work with Genji directly. MCP server for Genji API - Classical Japanese literature search and analysis.

What Genji does

A Model Context Protocol (MCP) server that provides access to the Genji API for classical Japanese literature analysis and search. This server enables AI assistants like Claude to search and analyze texts from classical Japanese literature with advanced normalization features.

Key capabilities

  • 🏥 Health Check: Monitor API status and availability
  • 🔍 Advanced Text Search: Search classical Japanese texts with sophisticated normalization options
  • ⚙️ Normalization Rules: Access and understand text normalization rules
  • 🔍 Normalization Preview: Preview how text will be normalized before processing
  • 🇯🇵 Classical Japanese Support: Specialized handling of historical Japanese text variations

Tools it exposes

Once connected, the assistant can call these 7 tools directly:

  • Full — text search of classical Japanese literature
  • macOS — Edit ~/Library/Application Support/Claude/claude_desktop_config.json:
  • Windows — The Windows tool exposed by this server
  • genji_health_check — The genji_health_check tool exposed by this server
  • genji_search — Searches classical Japanese texts with advanced normalization options
  • genji_get_normalization_rules — The genji_get_normalization_rules tool exposed by this server
  • genji_preview_normalization — The genji_preview_normalization tool exposed by this server

Installing the genji mcp server

The server is distributed via npm as @nakamura196/genji-mcp-server, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Requirements

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Genji sits in that group, and the shape of its toolset — Full, macOS, Windows among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • With 7 tools exposed, expect a noticeable bump in prompt size — disable it in projects that never use Genji.
  • Maintained by nakamura196, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the genji mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
