Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "chatspatial": {
      "command": "uvx",
      "args": [
        "chatspatial",
        "server"
      ]
    }
  }
}

Run this in your terminal

claude mcp add chatspatial -- uvx chatspatial server

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {

  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is ChatSpatial safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.6.0) reached the registry 20 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

ChatSpatial

MCP server for spatial transcriptomics analysis via natural language

ChatSpatial replaces ad-hoc LLM code generation with schema-enforced orchestration. Instead of generating arbitrary scripts, the LLM selects tools and parameters from a curated registry, making spatial transcriptomics workflows more reproducible across sessions and clients.

ChatSpatial exposes 20 schema-validated MCP tools that orchestrate 67 spatial transcriptomics methods across 13 analytical categories. The tools are the stable natural-language interface; the methods are the analysis backends selected through tool parameters.

The server implements MCP 2026-07-28 through the official Python SDK v2 and continues to serve 2025-11-25 clients through SDK-managed protocol negotiation. STDIO remains the secure local default; Streamable HTTP is available for explicitly configured HTTP deployments.

Start Here

Install uv once, then register ChatSpatial without creating or managing a Python environment:

Codex:

codex mcp add chatspatial -- uvx --from chatspatial chatspatial server

Claude Code:

claude mcp add --scope user chatspatial -- \

uvx --from chatspatial chatspatial server

uvx creates an isolated environment on first launch and reuses its cache on later launches. Restart the MCP client after adding the server.

The command above installs the standard runtime. To make all 15 composable Python method families available in the same isolated MCP environment, use:

uvx --from 'chatspatial[full]' chatspatial server

full includes CellRank, FastCCC, the maintained spatial-domain and registration backends, annotation, enrichment, and the other portable Python families. R bridges, AESTETIK, and rctd-py remain separate because they have system, platform, or large-runtime requirements. See the installation guide before enabling those families.

Then:

Run your first analysis — Quick Start
Choose optional method families or a persistent environment — Installation Guide
Configure another MCP client — Configuration Guide
Reproduce the manuscript key results without an LLM — Reproduction image

Docker quick start:

docker pull cafferyyang777/chatspatial:latest

Minimal example prompt:

Load /absolute/path/to/spatial_data.h5ad and plot gene expression at the spatial coordinates

The Quick Start provides a downloadable sample and a Leiden workflow that runs with the standard installation. Its sample has spatial coordinates but no H&E image. SpaGCN requires the optional spatial-domains extra.

If you use Docker, mount host data to /data and prompt with the container path, for example /data/spatial_data.h5ad.

ChatSpatial works with any MCP-compatible client — Claude Code, Claude Desktop, Codex, OpenCode, and other MCP-capable tools.

Reproducibility

Each release publishes a reproduction image under the -repro tag. It re-executes the DLPFC spatial-domain and OSCC CARD deconvolution tool calls recorded during the manuscript experiments, without calling any LLM, and compares the results with the reported values:

docker run --rm -v "$PWD/out:/outputs" \

cafferyyang777/chatspatial@sha256:ac3ba1ed8235c3d53ca72005d8ad2556cac007f5ddb932ae3e1d1241fa2cf9d8 \ chatspatial-reproduce

reproducibility/ contains the image definition and describes what it checks. The experiment and analysis scripts for the manuscript are in ChatSpatial-Reproducibility.
