ChatSpatial

MCP server for spatial transcriptomics analysis via natural language

Paper MLGenX @ ICLR 2026 ENAR 2026 IBC 2026 CI PyPI Python 3.11-3.14 License: MIT Docs Docker

ChatSpatial Overview

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 66 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.

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

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

Docker quick start:

docker pull ghcr.io/cafferychen777/chatspatial:v1.3.0

Minimal example prompt:

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.

Capabilities

Current coverage includes 66 methods across 15 analytical categories, exposed through 20 MCP tools. Supports 10x Visium, Xenium, Slide-seq v2, MERFISH, seqFISH.
