Questdb

This connects Claude to QuestDB, the open-source time-series database built for fast ingestion and SQL queries over timestamped data. You'd use it for IoT sensor data, financial ticks, application metrics, anything where you need to analyze time-series at scale. The skill wraps the Membrane CLI, which handles auth and credential refresh so you're not wrestling with tokens. You can search for pre-built actions by intent, run queries, or proxy raw requests when the standard actions don't cover your case. It's straightforward if you're already running QuestDB and need an agent to interact with your tables and schemas without manual API wrangling.

QuestDB

QuestDB is an open-source time-series database designed for high-performance data ingestion and querying. It's used by developers and organizations needing to analyze time-stamped data with SQL, like financial data, IoT sensor readings, or application metrics. They use it for building real-time dashboards, monitoring systems, and data analytics pipelines.

Working with QuestDB

This skill uses the Membrane CLI to interact with QuestDB. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.

Install the CLI

Install the Membrane CLI so you can run membrane from the terminal:

npm install -g @membranehq/cli@latest

Authentication

membrane login --tenant --clientName=<agentType>

This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.
