power-point-mcp

An MCP (Model Context Protocol) server that lets Claude read, create, and edit a single, pre-bound PowerPoint file. Bind the server to one .pptx and one optional template via environment variables; the server refuses to touch anything else on disk. Claude can then ask for slide metadata, list slides, read a slide's shapes, create the file from your template, and add new slides whose text comes only from the user.

Prerequisites

• Python 3.14 (matches .python-version).

• uv for environment and dependency management.

That is the entire toolchain. Nothing is installed globally.

Setup

git clone <this-repo-url> power-point-mcp
cd power-point-mcp
uv sync                  # runtime deps into a local .venv
uv sync --group dev      # add pytest for running the test suite

Configuration

The server is bound to a single PPTX file via environment variables:

If PPTX_TARGET is unset, the server refuses to start.

You can put these in a .env file at the repo root (copy .env.example) instead of exporting them every time. os.environ wins over .env so a one-off override on the command line still works. Run uv run power-point-mcp --doctor to validate the environment without starting the server.

Running locally

PPTX_TARGET=/abs/path/to/deck.pptx \
PPTX_TEMPLATE=/abs/path/to/template.pptx \
uv run power-point-mcp

The server speaks MCP over stdio (FastMCP's default transport).

Claude Desktop configuration

Add an entry like this to your Claude Desktop MCP config:

{
  "mcpServers": {
    "power-point-mcp": {
      "command": "uv",
      "args": ["run", "power-point-mcp"],
      "env": {
        "PPTX_TARGET": "/abs/path/to/deck.pptx",
        "PPTX_TEMPLATE": "/abs/path/to/template.pptx"
      }
    }
  }
}

Tools exposed

• presentation_info() — slide count, dimensions, layouts, master.

• list_slides() — index, layout, title, text snippet for every slide.

• list_layouts() — name, idx, and placeholder names for every layout.

• read_slide(slide_index) — every shape on one slide, with its text.

• create_presentation_from_template(overwrite=False) — initialise the bound target from PPTX_TEMPLATE.

• add_slide(layout_name, placeholders) — append a slide using a named layout; only fills placeholders you supply.

• set_slide_placeholder(slide_index, placeholder_name, text) — set a placeholder on an existing slide by name.

• set_slide_placeholder_by_idx(slide_index, placeholder_idx, text) — set a placeholder by its layout idx.

• set_slide_title(slide_index, text) — set the title placeholder of a slide.

• delete_slide(slide_index) — remove a slide.

• reorder_slide(slide_index, new_index) — move a slide to a new position.

Recommended companion skill

Pair this server with the academic-pptx-skill. It provides the slide-design conventions and prompts; this MCP gives Claude the file-system hands to actually write the deck.

Security note

The server only ever reads or writes PPTX_TARGET. Every path the tools receive is routed through a single security check that compares it against the bound target and rejects anything else. There is no network code in the package.

Development

uv sync --group dev
uv run pytest
