ChatSpatial

MCP server for spatial transcriptomics analysis via natural language

</div> <p align="center"> <img src="assets/images/overview.jpg" alt="ChatSpatial Overview" width="900"> </p>

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 65 spatial transcriptomics methods across 15 analytical categories. The tools are the stable natural-language interface; the methods are the analysis backends selected through tool parameters.

Start Here

Install ChatSpatial — Installation Guide for Python/uv setup, or Docker Guide for the GHCR image
Configure your MCP client — Configuration Guide
Run your first analysis — Quick Start

Docker quick start:

bash

docker pull ghcr.io/cafferychen777/chatspatial:v1.2.10

Minimal example prompt:

text

Load /absolute/path/to/spatial_data.h5ad and show me the tissue structure

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.
