Excel MCP Server (FsOpenXmlDsl)

Overview

Excel MCP Server (FsOpenXmlDsl) is a Model Context Protocol (MCP) server: Excel tools for AI agents: read/write, decompile to F#/C#/XML/JSON, or build from XML/JSON. Because it speaks the Model Context Protocol, AI assistants can use Excel MCP Server (FsOpenXmlDsl) as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the NuGet package Kookerella.FsOpenXmlDsl.Mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.6.0, published under the MIT license, with source at Kookerella-Ltd/Kookerella.FsOpenXmlDsl on GitHub.

On mcp.site, Excel MCP Server (FsOpenXmlDsl) sits in the File System category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
