KenTaniguchi-R maintains several open-source projects on GitHub, spanning personal finance, developer tooling, and AI integration.[^1][^2][^3][^4][^5][^6]

**Ledgr** is a self-hostable, open-source personal finance application licensed under AGPLv3. It features automatic bank synchronization and AI agent support, and is built with TypeScript, Next.js, and Docker.[^1][^7]

**Pier** is a Tauri-based macOS menu-bar launcher designed for personal CLI tools. Built with TypeScript and React, it allows users to drag and drop tools built with Claude Code.[^2][^8]

**Personal Info MCP** is a small MCP server that stores personal identity and professional details in an editable JSON file, enabling Claude AI to retrieve them without manual re-entry. It follows a privacy-first read/write split and is installed via `uvx`.[^3][^9]

**Pier-tools** provides a curated catalog of signed CLI tools that can be one-click added from the Pier app. Tools are defined with a YAML manifest and can be implemented as shell scripts or Go binaries, with automated signing and notarization via CI.[^4][^10]

**Claude Code Plugin Template** is a minimum-viable template for shipping private Claude Code plugins as private GitHub marketplaces. It includes a plugin marketplace setup and supports automatic updates when the version is bumped.[^5][^11]

**Semantic File Search** is a local-first semantic search tool for the filesystem. It is built in Swift, runs on Apple Silicon via MLX, and includes both a native macOS app and an MCP server.[^6]
