<p>This component allows agents to query data from Astra DB collections.</p>
<p>To use this tool in a flow, connect it to an <strong>Agent</strong> component.
The flow looks like this:</p>
<p><img decoding="async" loading="lazy" alt="Astra DB JSON tool connected to an Agent" src="/assets/images/component-astra-db-json-tool-117aff566c0df01a555264bb128b3693.png" width="4000" height="2742" class="img_ev3q"></p>
<p>The <strong>Tool Name</strong> and <strong>Tool Description</strong> fields are required for the Agent to decide when to use the tool.
<strong>Tool Name</strong> cannot contain spaces.</p>
<p>The values for <strong>Collection Name</strong>, <strong>Astra DB Application Token</strong>, and <strong>Astra DB API Endpoint</strong> are found in your Astra DB deployment. For more information, see the <a href="https://docs.datastax.com/en/astra-db-serverless/databases/create-database.html" target="_blank" rel="noopener noreferrer">DataStax documentation</a>.</p>
<p>In this example, an <strong>OpenAI</strong> embeddings component is connected to use the Astra DB tool component&#x27;s <strong>Semantic Search</strong> capability.
To use <strong>Semantic Search</strong>, you must have an embedding model or Astra DB Vectorize enabled.
If you try to run the flow without an embedding model, you will get an error.</p>
<p>Open the <strong>Playground</strong> and ask a question about your data.
The Agent uses the <strong>Astra DB Tool</strong> to return information about your collection.</p>
<h3 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="define-astra-db-tool-parameters">Define Astra DB tool parameters<a href="#define-astra-db-tool-parameters" class="hash-link" aria-label="Direct link to Define Astra DB tool parameters" title="Direct link to Define Astra DB tool parameters">​</a></h3>
<p>The <strong>Tool Parameters</strong> configuration pane allows you to define parameters for <a href="https://docs.datastax.com/en/astra-db-serverless/api-reference/document-methods/find-many.html#parameters" target="_blank" rel="noopener noreferrer">filter conditions</a> for the component&#x27;s <strong>Find</strong> command.</p>
<p>These filters become available as parameters that the LLM can use when calling the tool, with a better understanding of each parameter provided by the <strong>Description</strong> field.</p>
<ol>
<li>To define a parameter for your query, in the <strong>Tool Parameters</strong> pane, click <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-plus" aria-hidden="true"><path d="M5 12h14"></path><path d="M12 5v14"></path></svg> <strong>Add a new row</strong>.</li>
<li>Complete the fields based on your data. For example, with this filter, the LLM can filter by unique <code>customer_id</code> values.</li>
</ol>
<ul>
<li>Name: <code>customer_id</code></li>
<li>Attribute Name: Leave empty if the attribute matches the field name in the database.</li>
<li>Description: <code>&quot;The unique identifier of the customer to filter by&quot;</code>.</li>
<li>Is Metadata: <code>False</code> unless the value stored in the metadata field.</li>
<li>Is Mandatory: <code>True</code> to require this filter.</li>
<li>Is Timestamp: <code>False</code> since the value is an ID, not a timestamp.</li>
<li>Operator: <code>$eq</code> to look for an exact match.</li>
</ul>
<p>If you want to apply filters regardless of the LLM&#x27;s input, use the <strong>Static Filters</strong> option, which is available in the component&#x27;s <strong>Controls</strong> pane.</p>
<table><thead><tr><th>Parameter</th><th>Description</th></tr></thead><tbody><tr><td>Name</td><td>The name of the parameter that is exposed to the LLM. It can be the same as the underlying field name or a more descriptive label. The LLM uses this name, along with the description, to infer what value to provide during execution.</td></tr><tr><td>Attribute Name</td><td>When the parameter name shown to the LLM differs from the actual field or property in the database, use this setting to map the user-facing name to the correct attribute. For example, to apply a range filter to the timestamp field, define two separate parameters, such as <code>start_date</code> and <code>end_date</code>, that both reference the same timestamp attribute.</td></tr><tr><td>Description</td><td>Provides instructions to the LLM on how the parameter should be used. Clear and specific guidance helps the LLM provide valid input. For example, if a field such as <code>specialty</code> is stored in lowercase, the description should indicate that the input must be lowercase.</td></tr><tr><td>Is Metadata</td><td>When loading data using LangChain or Langflow, additional attributes may be stored under a metadata object. If the target attribute is stored this way, enable this option. It adjusts the query by generating a filter in the format: <code>{&quot;metadata.&lt;attribute_name&gt;&quot;: &quot;&lt;value&gt;&quot;}</code></td></tr><tr><td>Is Timestamp</td><td>For date or time-based filters, enable this option to automatically convert values to the timestamp format that the Astrapy client expects. This ensures compatibility with the underlying API without requiring manual formatting.</td></tr><tr><td>Operator</td><td>Defines the filtering logic applied to the attribute. You can use any valid <a href="https://docs.datastax.com/en/astra-db-serverless/api-reference/filter-operator-collections.html" target="_blank" rel="noopener noreferrer">Data API filter operator</a>. For example, to filter a time range on the timestamp attribute, use two parameters: one with the <code>$gt</code> operator for &quot;greater than&quot;, and another with the <code>$lt</code> operator for &quot;less than&quot;.</td></tr></tbody></table>
