Mozisu MCP Server

What is Mozisu MCP Server?

Mozisu MCP Server is a Model Context Protocol server that counts characters (including spaces and non-whitespace) and returns the result. It helps LLMs generate text with precise character counts, supporting multi‑byte characters such as Japanese and emoji. It can be used as an MCP server, a command‑line tool, or a web interface.

How to use Mozisu MCP Server?

Clone the repository, install dependencies with go mod download, and build using task build. To use with Claude Desktop, add the path to the built binary to the mcpServers section of claude_desktop_config.json. Alternatively, run it directly with go run cmd/mcpserver/main.go for the MCP server, ./bin/charcount "text" for CLI usage, or ./bin/webserver to launch the web interface at http://localhost:8080.
