Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account Aimino-Tech for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server for reading, creating and editing Office documents (Excel, Word, PowerPoint) and PDFs, including filling PDF forms.

What you can do: List supported formats and read file metadata, and read documents into Markdown, JSON, text or chunks for the assistant to work with.
When to use it: Use it when an assistant needs to work with local Office files or PDFs: extracting content for analysis, generating spreadsheets, reports or slide decks, or filling in PDF forms from data the assistant has read.
Requirements: Runs as a local process on the user's machine (desktop only, not web-executable). The README installs it with cargo or a GitHub release; the manifest lists an npm package run with npx. No accounts, API keys or environment variables are declared.

Before you install

Many tools write files: creating and editing XLSX, DOCX and PPTX, replacing text, deleting sheets, and writing filled or overlaid PDFs to an output path. Point it only at documents you are willing to change, and review generated or filled files before relying on them.

Installation

In SourceWeft

Open Office Oxide Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Rust-native MCP server for Office document processing (Excel, Word, PowerPoint, PDF).
Sub-millisecond, local-first, open source — the "open source Aspose."

PDFs are a pain. We live in bureaucratic countries where every form asks for your name, address, and date of birth — over and over. Bank applications, tax forms, insurance claims, government permits, rental agreements. Same fields, different PDFs, endless typing.
Stop filling forms by hand. Let office-oxide-mcp do it in milliseconds — whether it's a simple AcroForm, a complex XFA form, or a flat scanned PDF where you need coordinates. Your LLM reads the form, you approve, it fills. Done.
