MCP Server for Brazilian ICD-10 (DATASUS) - International Classification of Diseases

A Model Context Protocol (MCP) server that provides access to the Brazilian version of ICD-10 (CID-10), maintained by DATASUS/Ministry of Health of Brazil.

See it in action

Ask your assistant, in plain Portuguese:

• "Qual o código CID-10 para infarto agudo do miocárdio?" → cid10_search / cid10_lookup
• "Liste todas as subcategorias do diabetes tipo 2 (E11)." → cid10_hierarchy
• "O código C50 é válido e pode ser causa de óbito?" → cid10_validar

The answers come straight from the bundled DATASUS V2008 dataset — official codes and descriptions, not guesses from training data.

Features

• Search - Search codes by term (code or description)
• Lookup - Get detailed information for a specific CID-10 code
• Hierarchy - Navigate the hierarchical structure (chapters, groups, categories, subcategories)
• Statistics - General statistics about the CID-10 database
• Validation - Validate codes for use in health systems (SUS)

Installation

Using with Claude Desktop

Add to your Claude Desktop configuration file:

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "cid10-br": {
      "command": "npx",
      "args": ["cid10-br-mcp"]
    }
  }
}

Global Installation

npm install -g cid10-br-mcp

Then add to Claude Desktop config:

{
  "mcpServers": {
    "cid10-br": {
      "command": "cid10-br-mcp"
    }
  }
}

Available Tools

Tool	Description
cid10_search	Search CID-10 codes by term (code or description)
cid10_lookup	Get detailed information for a specific code
cid10_hierarchy	Get all codes under a category/prefix
cid10_capitulos	List all 22 chapters of CID-10
cid10_stats	General statistics about the database
cid10_validar	Validate a code for use in health systems

Usage Examples

Once configured, you can ask Claude:

• "What is CID-10 code A90?"
• "Search for diabetes codes in CID-10"
• "List all codes under category E11"
• "What are the chapters of CID-10?"
• "Is F32.1 a valid code for medical records?"

Data Source

The data comes from official DATASUS sources:

• CID-10-CAPITULOS.CSV - 22 chapters
• CID-10-GRUPOS.CSV - Groups within chapters
• CID-10-CATEGORIAS.CSV - 3-character categories
• CID-10-SUBCATEGORIAS.CSV - Detailed subcategories
