ChatSpatial: Natural language-driven spatial transcriptomics analysis via Model Context Protocol (MCP) integration

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.

It exposes 60+ spatial transcriptomics methods as MCP tools, so any MCP-compatible client can analyze data through natural language.

Start Here

1. Install ChatSpatial — Installation Guide
2. Configure your MCP client — Configuration Guide
3. Run your first analysis — Quick Start

Minimal example prompt:

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

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