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:

Organizations List: influxdb://orgs
- Displays all organizations in the InfluxDB instance
Buckets List: influxdb://buckets
- Shows all buckets with their metadata
Bucket Measurements: influxdb://bucket/{bucketName}/measurements
- Lists all measurements within a specified bucket
Query Data: influxdb://query/{orgName}/{fluxQuery}
- Executes a Flux query and returns results as a resource

Tools

The server provides these tools:

write-data: Write time-series data in line protocol format
- Parameters: org, bucket, data, precision (optional)
query-data: Execute Flux queries
- Parameters: org, query
create-bucket: Create a new bucket
- Parameters: name, orgID, retentionPeriodSeconds (optional)
create-org: Create a new organization
- Parameters: name, description (optional)

Prompts

The server offers these prompt templates:

flux-query-examples: Common Flux query examples
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

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.

Testing
