What is InfluxDB

InfluxDB MCP Server is a Model Context Protocol server that enables interaction with an InfluxDB instance through the InfluxDB OSS API v2. It is primarily designed for developers who need a structured way to manage time-series data within InfluxDB.

Use cases

This server can be utilized for various purposes including managing organizational data, interacting with time-series buckets, executing complex queries, and writing data in line protocol format. It is ideal for applications that require efficient data retrieval and manipulation from InfluxDB databases.

How to use

To use the InfluxDB MCP Server, set the required environment variables including the InfluxDB authentication token and optionally the InfluxDB URL and organization name. The server can be run directly using npx for a quick start or installed globally for more persistent use. Additionally, it can be integrated into custom configurations for environments like Claude for Desktop.

Key features

Key features of the InfluxDB MCP Server include resources for listing organizations and buckets, executing Flux queries, writing data, and managing database objects. It also offers prompt templates for common Flux queries and guides for line protocol format, making it easier for users to interact with InfluxDB.

Where to use

The InfluxDB MCP Server can be used in any application or development environment that requires real-time data monitoring and management. It’s particularly useful for IoT applications, financial analytics, and any system that generates time-series data and needs efficient querying and storage solutions.

InfluxDB MCP Server

A Model Context Protocol (MCP) server that exposes access to an InfluxDB instance using the InfluxDB OSS API v2. Mostly built with Claude Code.

Features

This MCP server provides:

• Resources: Access to organization, bucket, and measurement data
• Tools: Write data, execute queries, and manage database objects
• Prompts: Templates for common Flux queries and Line Protocol format

Resources

The server exposes the following resources:

1. Organizations List: influxdb://orgs

   • Displays all organizations in the InfluxDB instance

2. Buckets List: influxdb://buckets

   • Shows all buckets with their metadata

3. Bucket Measurements: influxdb://bucket/{bucketName}/measurements

   • Lists all measurements within a specified bucket

4. Query Data: influxdb://query/{orgName}/{fluxQuery}

   • Executes a Flux query and returns results as a resource

Tools

The server provides these tools:

1. write-data: Write time-series data in line protocol format

   • Parameters: org, bucket, data, precision (optional)

2. query-data: Execute Flux queries

   • Parameters: org, query

3. create-bucket: Create a new bucket

   • Parameters: name, orgID, retentionPeriodSeconds (optional)

4. create-org: Create a new organization

   • Parameters: name, description (optional)

Prompts

The server offers these prompt templates:

1. flux-query-examples: Common Flux query examples
2. line-protocol-guide: Guide to InfluxDB line protocol format

Configuration

The server requires these environment variables:

• INFLUXDB_TOKEN (required): Authentication token for the InfluxDB API
• INFLUXDB_URL (optional): URL of the InfluxDB instance (defaults to http://localhost:8086)
• INFLUXDB_ORG (optional): Default organization name for certain operations

Installation

Installing via Smithery

To install InfluxDB MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @idoru/influxdb-mcp-server --client claude

Option 1: Run with npx (recommended)

# Run directly with npx
INFLUXDB_TOKEN=your_token npx influxdb-mcp-server

Option 2: Install globally

# Install globally
npm install -g influxdb-mcp-server

# Run the server
INFLUXDB_TOKEN=your_token influxdb-mcp-server

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.
