# Neo4j

> Run Cypher queries against Neo4j graph databases.

The `Neo4jResourceClient` allows you to execute Cypher queries against Neo4j graph databases for node and relationship operations.

## Usage

```typescript theme={null}
import { myNeo4jClient } from "./clients";

const result = await myNeo4jClient.invoke(
  "MATCH (u:User {id: $id}) RETURN u",
  { id: "123" },
  "get-user"
);

if (result.ok) {
  console.log(result.result.rows);
}
```

## Inputs

The `invoke` method accepts the following arguments:

<ParamField path="cypher" type="string" required>

</ParamField>

<ParamField path="params" type="Record<string, unknown>">

  A unique identifier for this operation, used for tracing and logging.
</ParamField>

<ParamField path="timeoutMs" type="number">
  Optional timeout in milliseconds for the query execution.

<ResponseField name="kind" type="&#x22;database&#x22;">
  Discriminator for the response type.
</ResponseField>

<ResponseField name="rows" type="Record<string, unknown>[]">
  An array of objects representing the records returned by the query.
