[Tools](/oss/javascript/langchain/tools) are utilities designed to be called by a model: their inputs are designed to be generated by models, and their outputs are designed to be passed back to models. A [toolkit](/oss/javascript/langchain/tools#prebuilt-tools) is a collection of tools meant to be used together. ## Integration platforms The following platforms provide access to multiple tools and services through a unified interface: | Tool/Toolkit | Number of Integrations | Pricing | Key Features | | --------------------------------------------------------- | ---------------------- | ------------------- | ---------------------------------------------------------- | | [`Composio`](/oss/javascript/integrations/tools/composio) | 500+ | Free tier available | OAuth handling, event-driven workflows, multi-user support | ## All tools and toolkits
