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

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

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

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)

The server offers these prompt templates:

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

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

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

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

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

# Install globally npm install -g influxdb-mcp-server # Run the server INFLUXDB_TOKEN=your_token influxdb-mcp-server

# 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

influxdb-mcp-server uses stdio transport by default. You can explicitly request it with --stdio, or start the server with Streamable HTTP transport by providing the --http option with an optional port number (defaults to 3000). This mode uses an internal Express.js server:

# Start with Streamable HTTP transport on default port 3000 INFLUXDB_TOKEN=your_token npm start -- --http # Start with Streamable HTTP transport on a specific port INFLUXDB_TOKEN=your_token npm start -- --http 8080

If you installed globally or are using npx, you can run:

INFLUXDB_TOKEN=your_token influxdb-mcp-server --http # or explicitly force stdio INFLUXDB_TOKEN=your_token influxdb-mcp-server --stdio # or INFLUXDB_TOKEN=your_token influxdb-mcp-server --http 8080

Add the server to your claude_desktop_config.json:

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

{ "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" } } } }

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.

The repository includes comprehensive integration tests that:

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

To run the tests:

npm test
