InfluxDB MCP Server

A Model Context Protocol (MCP) server that provides secure, read-only access to InfluxDB 1.8 via JWT authentication.

Overview

InfluxDB MCP Server allows AI assistants to query time-series data stored in InfluxDB through a standardized interface. It provides read-only access to your InfluxDB instance with authentication via JWT tokens.

Prerequisites

Docker
InfluxDB 1.8 instance (already running)
Credentials for your InfluxDB instance

Installation

Clone the repository:
git clone https://github.com/m4tyn0/influx_mcp cd influxdb-mcp-server
Create a .env file with your configuration :
cp env.example .env
INFLUXDB_HOST= INFLUXDB_PORT=8086 INFLUXDB_USERNAME= INFLUXDB_PASSWORD= INFLUXDB_SSL=false INFLUXDB_VERIFY_SSL=true INFLUXDB_TIMEOUT=10 JWT_SECRET= JWT_ALGORITHM=HS256
Build and run the Docker container:
docker build -t influxdb-mcp-server . docker run -d --env-file .env -p 8000:8000 influxdb-mcp-server

JWT Authentication

The server uses JWT tokens for authentication. You need to generate a token to authenticate with the MCP server, here is a simple script to do that:

import jwt
import datetime

# Create a token
payload = {
    "sub": "username",  # Replace with the username you want to identify with
    "iat": datetime.datetime.utcnow(),
    "exp": datetime.datetime.utcnow() + datetime.timedelta(hours=1)
}
token = jwt.encode(payload, "your-jwt-secret", algorithm="HS256")
print(token)

Save this token for use with your MCP client.

Using with MCP Clients

Authenticate with the MCP server using the JWT token:
Tool: auth Arguments: {"token": "your.jwt.token.here"}
Query your InfluxDB data:
Tool: list_databases Arguments: {}
Tool: list_measurements Arguments: {"database": "your_database_name"}
Tool: query Arguments: { "database": "your_database_name", "query": "SELECT * FROM measurement_name LIMIT 10" }

Troubleshooting

If you encounter issues:

Connection errors to InfluxDB:
- Verify the INFLUXDB_HOST is correct and accessible from the Docker container
- Check that your InfluxDB credentials are correct
- Ensure your InfluxDB instance is configured to accept connections from external hosts
Authentication issues:
- Verify your JWT_SECRET is set correctly
- Ensure the token you're using matches the JWT_SECRET and hasn't expired
- Check that your InfluxDB credentials have read access to the databases
Check logs:
docker logs

Security Notes

The MCP server only allows read-only access to your InfluxDB instance
All queries are validated to ensure they begin with SELECT
JWT authentication protects access to the MCP server
Consider running the server in a private network for additional security
