▪ Tools & Triggers
Supported Tools and Triggers
Every Needle action and event your agent gets out of the box.
Add files to a collection
Tool to add files to a collection by providing file URLs. Use when you need to add one or more files to an existing collection. URLs can be public or private (generated via the Files API).
Add Files to Local Connector
Tool to add files to a local connector by providing file metadata. Use when you need to add external files to a connector using their URLs.
Create Collection
Tool to create a new collection. Use after confirming the collection name.
Create Local Connector
Tool to create a local connector that monitors specified folders on a device. Use when setting up file indexing from a local machine into Needle collections.
Delete files from a collection
Tool to delete files from a specific collection by providing file IDs. Use after confirming valid file IDs to remove from the collection.
Delete files from local connector
Tool to delete files from a local connector by filename or file IDs. Use when you need to remove files from a connector's local storage.
Get Collection
Tool to retrieve details for a specific collection by its ID. Use when you need to get collection metadata including name, creation date, and search query count.
Get collection stats
Tool to retrieve statistics for a specific collection by its ID. Use when you need document count, index size, and timestamps after confirming the collection exists. Zero document count is a valid response for empty collections, not an error.
Get File Download URL
Tool to get a short-lived signed private download URL for a Needle file. Use when you need to retrieve file content but the public storage URL requires authentication. The returned URL should be used immediately as it expires quickly.
Get File Upload URL
Tool to get signed URLs for uploading local files to Needle. Use when you need to upload files to a collection. The upload URLs are valid for a short time, so upload files immediately after receiving the URLs. Multiple content types can be specified to generate multiple upload URLs in a single request.
Get local connector
Tool to retrieve details of a local connector by its ID. Use when you need information about a specific local connector's configuration, device details, and associated folders.
List Collection Files
Tool to list all files within a specific collection by its ID. Returns file metadata (including file URLs) only — not document text content; fetch file URLs separately to access content. Use when you have a collection ID and need to retrieve its files. Supports pagination.
List Collections
Tool to list collections. Use after authenticating with your API key to page through collections. Similar collection names can exist; always verify the correct `collection_id` from results before performing subsequent operations.
List Connectors
Tool to list connectors. Use to retrieve all configured connectors in your account.
List Local Connectors
Tool to list local connectors. Use to retrieve all local connectors configured in your Needle account.
Search Collection
Tool to perform semantic search within a specific Needle collection and return ranked results with source references. Use when you need to retrieve relevant content from a known collection using natural language queries.
