Cochrane Meta-Analysis MCP Server

An MCP (Model Context Protocol) server that provides AI-assisted meta-analysis workflows following Cochrane methodological standards.

Features

  • RevMan Import: Parse RevMan 5 (.rm5 XML) and Cochrane CSV exports

  • Data Validation: Comprehensive validation against Cochrane standards

  • Meta-Analysis: R-based statistical analysis using metafor/meta packages

  • Forest Plots: Publication-ready visualizations

  • Publication Bias: Funnel plots, Egger's test, trim-and-fill

  • Reporting: Automated Cochrane-style HTML/PDF reports

Installation

npm install
npm run build

Prerequisites

  1. Node.js 18+

  2. R 4.0+ with packages:

    "cochrane-meta": {
      "command": "node",
      "args": ["/Users/YOUR_USERNAME/Documents/cochrane-meta-mcp/dist/index.js"]
    }
  }
}

Example Usage with Claude

User: I have a Cochrane CSV file with 10 RCTs comparing intervention A vs control.
      Can you help me run a meta-analysis?

Claude: I'll help you analyze this. First, let me import the data using the import_revman_data tool...

[Uses import_revman_data]

Claude: Great! I've imported 10 studies. Let me validate the data...

[Uses validate_cochrane_data]

Claude: Validation passed with 2 warnings about small sample sizes.
        Now I'll perform the meta-analysis using a random-effects model
        with odds ratios as the effect measure...

[Uses perform_meta_analysis]

Claude: The pooled OR is 0.75 (95% CI: 0.62-0.91), p=0.003, with moderate
        heterogeneity (I²=45%). Let me generate a forest plot...

[Uses generate_forest_plot]

Claude: Forest plot created. Now checking for publication bias...

[Uses assess_publication_bias]

Claude: Egger's test p=0.42, no evidence of publication bias.
        Generating final report...

[Uses generate_cochrane_report]

Claude: Complete! Your meta-analysis report is ready at report.html

CSV Format

For CSV imports, use this format:

study_id,authors,year,title,intervention,comparison,outcome,events_treatment,n_treatment,events_control,n_control
Study1,Smith 2020,2020,RCT of intervention,Drug A,Placebo,Mortality,10,100,20,100
Study2,Jones 2021,2021,Another RCT,Drug A,Placebo,Mortality,15,150,30,150

For continuous outcomes:

study_id,authors,year,title,intervention,comparison,outcome,mean_treatment,sd_treatment,n_treatment,mean_control,sd_control,n_control
