Officekit Opencode

Fast, single-binary document tools for AI coding agents. One 760 KB Rust binary speaks MCP over stdio — no Python, no Node, no Microsoft Office, no approvals from anyone. Works with OpenCode, Claude Code, and Codex.

What it does (v0.1 — PowerPoint)

Tool	What
pptx_create	New 16:9 deck with all 11 standard PowerPoint layouts
pptx_add_slide	Add a slide by layout name (Title Slide, Two Content, …)
pptx_set_text	Fill placeholders / shapes: paragraphs, bullets, levels, bold, size, color, align
pptx_add_image	Insert png/jpg/gif; auto aspect-ratio and auto-fit-to-slide
pptx_add_textbox	Free-form text boxes anywhere
pptx_duplicate_slide	Clone a slide (text + images)
pptx_delete_slide	Remove a slide
pptx_inspect	Full structural dump: shapes, placeholders, positions, text
pptx_extract_text	Read all text from a deck

Edits work on existing .pptx files created by PowerPoint, python-pptx, etc. Every operation saves atomically (tmp + rename).

Install

Prebuilt binaries for Linux (x64/arm64, gnu/musl), macOS (x64/arm64) and Windows (x64): GitHub Releases.

Or build from source (needs Rust):

cargo build --release
cp target/release/officekit ~/.local/bin/

OpenCode (npm package)

Published as officekit-opencode. One line in config — the package downloads the right binary for your platform automatically (falls back to an officekit binary on PATH):

// ~/.config/opencode/opencode.jsonc
{
  "plugins": ["officekit-opencode"]
}

You get: the officekit MCP server, a presentations skill, and a /deck command. Options via plugin config:

{ "plugins": [{ "package": "officekit-opencode",
                "options": { "command": "/usr/local/bin/officekit" } }] }

Or from a local checkout:

{ "plugins": ["/path/to/officekit/plugin/opencode"] }

Or skip the plugin and register the server directly:

opencode mcp add officekit --global -- officekit

Claude Code

claude mcp add officekit -- officekit

Codex

codex mcp add officekit -- officekit

• xlsx (Excel): cells, formulas, styles, charts
• pptx: tables, charts, shape styling, slide reordering, notes
• prebuilt binaries for linux/macOS/windows via GitHub releases
