GitHub - idoru/influxdb-mcp-server: An MCP Server for querying InfluxDB (original) (raw)

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

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

The repository includes comprehensive integration tests that:

• Spin up a Docker container with InfluxDB
• Populate it with sample data
• Test all MCP server functionality
