Install

Manual install

uv sync

Option A from the README: install dependencies in the repository folder, then start with `uv run originlab-mcp`.

Access and checks

How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • The server drives Origin through COM, reads and imports files and saves or overwrites projects and figures.

This is third-party code. Review the repository files before installing.

What it does

OriginLab MCP links an AI client to an installed OriginLab. On a plain-language request the agent imports CSV and Excel, builds graphs, changes axes, colors, symbols and fonts, runs analysis and exports a figure such as PNG. The Python server runs over stdio and reaches Origin through `originpro` and COM. The first tool call connects to the local installation by itself. A local status panel checks the Origin link, lists open worksheets and graphs and writes the MCP configuration for Cursor, Codex, Claude Desktop and other clients.

Who it is for. Researchers and engineers who plot and fit curves in OriginLab and want to drive that work in conversation with an agent.

Good fit when

  • Experiment results sit in a CSV and need a graph with labeled axes.
  • A Gaussian is fitted to a point set and the figure exported to PNG.
  • A batch of graphs gets one style of colors, symbols and fonts.
  • An agent reads open Origin worksheets and lists columns with labels.

Not a fit when

  • The computer does not run Windows.
  • You have no license for OriginLab 2021 or newer.
  • You need a general plotting library without Origin, such as Matplotlib.

Example request

Import experiment.csv from my desktop, use the first column as X, make a scatter plot, run a Gaussian fit and export a PNG.

Limitations

Windows only. Needs OriginLab 2021 or newer with a valid license and Python 3.10 or newer. The project is at version 0.2.1 and result formats are still changing. The `originlab-mcp-ui` panel edits client configuration files and makes a `.bak` copy first. Some results, such as fit parameters, come back in a format described in the `docs` files and may change between versions.

How to disable. Remove the `originlab` entry from the client configuration and stop the `originlab-mcp` process. Origin files stay untouched.

FAQ

How do I start OriginLab MCP?

Run `uv sync` in the project folder and `uv run originlab-mcp`. With pip use `pip install -e .` and then `originlab-mcp`.

Does the server work on macOS or Linux?

No. Origin is driven through COM, so the server targets Windows only.

How do I check the link to Origin?

Run `uv run originlab-mcp-ui` and open `http://127.0.0.1:8765/`. The page tests the link and shows open worksheets.

Which clients are supported?

Antigravity and Gemini, Cursor, Codex, Trae and Claude Desktop. The `originlab-mcp-ui` panel writes their configuration.

How many tools does the server have?

Sixty-seven. Graph customization alone takes 25: axes, lines, fonts, colors, symbols and error bars.
