OpenProblems Spatial Transcriptomics MCP Server - Implementation Summary

🎯 Project Overview

We have successfully implemented a Model Context Protocol (MCP) server for the OpenProblems project, specifically designed to enable AI agents to interact with spatial transcriptomics workflows. This server acts as a standardized bridge between AI applications and complex bioinformatics tools (Nextflow, Viash, Docker).

🧬 Usage Examples

For AI Agents

The MCP server enables AI agents to perform complex bioinformatics operations:

# AI agent can execute Nextflow workflows
result = await session.call_tool("run_nextflow_workflow", {
    "workflow_name": "main.nf",
    "github_repo_url": "https://github.com/openproblems-bio/task_ist_preprocessing",
    "profile": "docker",
    "params": {"input": "spatial_data.h5ad", "output": "processed/"}
})

# AI agent can access documentation for context
docs = await session.read_resource("documentation://nextflow")
nextflow_best_practices = json.loads(docs)

# AI agent can analyze failed workflows
analysis = await session.call_tool("analyze_nextflow_log", {
    "log_file_path": "work/.nextflow.log"
})

For Researchers

Direct CLI usage for testing and development:

# Execute a tool directly
openproblems-mcp tool echo_test message="Hello World"

# Analyze a Nextflow log
openproblems-mcp tool analyze_nextflow_log log_file_path="/path/to/.nextflow.log"

# List all available capabilities
openproblems-mcp info
