Option 3: From source

# Clone the repository
git clone https://github.com/idoru/influxdb-mcp-server.git
cd influxdb-mcp-server

# Install dependencies
npm install

# Run the server
INFLUXDB_TOKEN=your_token npm start

Integration with Claude for Desktop

Add the server to your claude_desktop_config.json:

Using npx (recommended)

{
  \"mcpServers\": {
    \"influxdb\": {
      \"command\": \"npx\",
      \"args\": [\"influxdb-mcp-server\"],
      \"env\": {
        \"INFLUXDB_TOKEN\": \"your_token\",
        \"INFLUXDB_URL\": \"http://localhost:8086\",
        \"INFLUXDB_ORG\": \"your_org\"
      }
    }
  }
}

If installed locally

{
  \"mcpServers\": {
    \"influxdb\": {
      \"command\": \"node\",
      \"args\": [\"/path/to/influxdb-mcp-server/src/index.js\"],
      \"env\": {
        \"INFLUXDB_TOKEN\": \"your_token\",
        \"INFLUXDB_URL\": \"http://localhost:8086\",
        \"INFLUXDB_ORG\": \"your_org\"
      }
    }
  }
}

Code Structure

The server code is organized into a modular structure:

• src/
  • index.js - Main server entry point
  • config/ - Configuration related files
    • env.js - Environment variable handling
  • utils/ - Utility functions
    • influxClient.js - InfluxDB API client
    • loggerConfig.js - Console logger configuration
  • handlers/ - Resource and tool handlers
    • organizationsHandler.js - Organizations listing
    • bucketsHandler.js - Buckets listing
    • measurementsHandler.js - Measurements listing
    • queryHandler.js - Query execution
    • writeDataTool.js - Data write tool
    • queryDataTool.js - Query tool
    • createBucketTool.js - Bucket creation tool
    • createOrgTool.js - Organization creation tool
  • prompts/ - Prompt templates
    • fluxQueryExamplesPrompt.js - Flux query examples
    • lineProtocolGuidePrompt.js - Line protocol guide

This structure allows for better maintainability, easier testing, and clearer separation of concerns.

Testing

The repository includes comprehensive integration tests that:

• Spin up a Docker container with InfluxDB
• Populate it with sample data
