MCP server for LibreOffice automation — presentations, documents, spreadsheets

LibreOffice MCP Server

A Model Context Protocol (MCP) server that gives agentic coding tools programmatic control over presentations (pptx), documents (docx), and spreadsheets (xlsx) — plus PDF export via LibreOffice headless mode.

Works with any MCP-compatible agent: Claude Code, Codex, OpenCode, Pi Agent, Cursor, Windsurf, etc.

Agent Configuration (Tested Locally)

Claude Code

Add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "libreoffice": {
      "command": "libreoffice-mcp"
    }
  }
}

If libreoffice-mcp is not on your PATH, use the full path to the binary (e.g. ~/.local/bin/libreoffice-mcp or your venv path).

Restart Claude Code with Ctrl+Shift+P → "Restart Claude Code Server".

OpenCode

Add under mcpServers in ~/.config/opencode/opencode.jsonc:

    "libreoffice": {
      "type": "local",
      "command": ["libreoffice-mcp"],
      "enabled": true
    }

Use the full binary path if it's not on your PATH.

Restart OpenCode.

Hermes Agent

Add under mcp_servers in ~/.hermes/config.yaml:

  libreoffice:
    command: libreoffice-mcp
    enabled: true

Use the full binary path if needed.

Quickstart Example

Create a presentation with 3 slides programmatically:

# Agent calls these via MCP tools

1. presentation_create {"output_path": "/tmp/deck.pptx"}
2. presentation_set_title  {"file_path": "/tmp/deck.pptx", "slide_index": 0, "title": "Quarterly Review"}
3. presentation_add_bullets {"file_path": "/tmp/deck.pptx", "slide_index": 0, "bullets": ["Revenue +24%", "8 releases shipped", "1.2M users"]}
4. presentation_add_slide {"file_path": "/tmp/deck.pptx", "layout": "title_and_content"}
5. presentation_set_title {"file_path": "/tmp/deck.pptx", "slide_index": 1, "title": "Roadmap"}
6. presentation_add_bullets {"file_path": "/tmp/deck.pptx", "slide_index": 1, "bullets": ["Q3: Foundation", "Q4: Acceleration", "Q1: Scale"]}
7. presentation_export_pdf {"file_path": "/tmp/deck.pptx"}

Troubleshooting

soffice not found when exporting PDF

Make sure LibreOffice is installed and soffice is on your PATH:

which soffice
soffice --version

On macOS, Homebrew sometimes links it as /opt/homebrew/bin/soffice. Ensure your shell PATH includes this.

MCP tools not appearing

• Check the agent's MCP server logs for connection errors.
• Verify libreoffice-mcp runs standalone: echo '{}' | libreoffice-mcp
• Ensure Python dependencies are installed: pip install python-pptx openpyxl python-docx mcp
