🧰 Available Tools

| Tool | Description | Parameters | |------|--------------|-------------| | resx.read | Read .resx as UTF-8 text | { "file": "path/to/file.resx" } | | resx.write | Write UTF-8 text (atomic replace) | { "file": "path/to/file.resx", "content": "", "backup": true } | | resx.setEntry | Add or update a key/value pair | { "file": "path/to/file.resx", "name": "Key", "value": "Value", "comment": "Optional" } | | resx.removeEntry | Remove a key from .resx | { "file": "path/to/file.resx", "name": "Key" } |

⚠️ Installation Notice

Some users may try to install this project with:

gemini extensions install https://github.com/miaofalianhua/ResxMcp

⚠️ Do NOT do this repeatedly! This command triggers Google’s extension registry verification and may result in rate limit errors (HTTP 429) or installation failure.

👉 The correct way to use ResxMcp is as a local MCP server, not a regular Gemini extension.

---

✅ Recommended Installation

1️⃣ Build the project

dotnet publish -c Release -r win-x64 -p:PublishSingleFile=true -o ./publish

2️⃣ Register with Gemini CLI

gemini mcp add resx-tool "./publish/ResxMcp.exe"

3️⃣ Verify installation

gemini @resx-tool tools/list

You should see tools such as: resx.read, resx.write, resx.setEntry, and resx.removeEntry.

💡 Tip: If you wish to distribute it as an installable Gemini extension, use the included gemini-extension.json (v1.0.2). It wraps this MCP server for one-command installation when the registry supports MCP-only extensions.

---

🚀 Quick Start

1. Build your .NET project with localization resources.
2. Use resx.read to inspect .resx content.
3. Modify, translate, or generate .resx files automatically with your MCP tools.
4. Use resx.write or resx.setEntry to update keys or values.

🖥️ Example Usage

gemini @resx-tool tools/call resx.setEntry --arguments '{"file":"lang.zh-CN.resx","name":"App.Title","value":"Triad Controls"}'
