  • schema://database: Database schema information

Prompts

  • indication-landscape: Analyzes clinical trial patterns for a given therapeutic area
    • Required: topic (e.g., "multiple sclerosis", "breast cancer")

Tools

  • read-query: Execute SELECT queries on the AACT database
  • list-tables: Get available tables in the AACT database
  • describe-table: View schema information for a specific table
  • append-insight: Add new analysis findings

  1. Create a free account at https://aact.ctti-clinicaltrials.org/users/sign_up
  2. Set environment variables:
    • DB_USER: AACT database username
    • DB_PASSWORD: AACT database password

Usage with Claude Desktop

Note that you need Claude Desktop and a Claude subscription at the moment.

Add one of the following configurations to the file claude_desktop_config.json. (On macOS, the file is located at /Users/YOUR_USERNAME/Library/Application Support/Claude/claude_desktop_config.json and you will need to create it yourself if it does not exist yet).

Option 1: Using the published package

"mcpServers": {
    "CTGOV-MCP": {
      "command": "uvx",
      "args": [
        "mcp-server-aact"
      ],
      "env": {
        "DB_USER": "USERNAME",
        "DB_PASSWORD": "PASSWORD"
      }
    }
}

Option 2: Running from source (development)

"mcpServers": {
    "CTGOV-MCP-DEV": {
      "command": "uv",
      "args": [
        "--directory",
        "PATH_TO_REPOSITORY",
        "run",
        "mcp-server-aact"
      ],
      "env": {
