> API Reference / Projects / Retrieve connection URI

## GET /projects//connection\_uri

Retrieves a connection URI for the specified database.
The URI uses the standard PostgreSQL connection string format. Set `pooled=true` to include the `-pooler` suffix for a connection pooler URI.

### Parameters

- `project_id` (string, path, required)
  The Neon project ID
- `branch_id` (string, query, optional)
  The branch ID. Defaults to your project's default `branch_id` if not specified.
- `endpoint_id` (string, query, optional)
  The endpoint ID. Defaults to the read-write `endpoint_id` associated with the `branch_id` if not specified.
- `database_name` (string, query, required)
  The database name
- `role_name` (string, query, required)
  The role name
- `pooled` (boolean, query, optional)
  Adds the `-pooler` option to the connection URI when set to `true`, creating a pooled connection URI.

### Response (200)

```json
{
  "uri": "postgresql://[user]:[password]@ep-cool-darkness-a5b6c7d8.us-east-2.aws.neon.tech/dbname?sslmode=require&channel_binding=require"
}
```

### Code examples

```bash
curl "https://console.neon.tech/api/v2/projects/$PROJECT_ID/connection_uri?database_name=$DATABASE_NAME&role_name=$ROLE_NAME" \
  -H "Authorization: Bearer $NEON_API_KEY"
```

```typescript
import { createNeonClient, raw } from '@neon/sdk';

const neon = createNeonClient({ apiKey: process.env.NEON_API_KEY });
const { data } = await raw.getConnectionUri({
  client: neon.client,
  path: {
    project_id: process.env.PROJECT_ID
  },
  query: {
    database_name: process.env.DATABASE_NAME,
    role_name: process.env.ROLE_NAME
  }
});
```

```bash
# neonctl
neon connection-string [branch]
```

### MCP

Tool: `get_connection_string`

Get a PostgreSQL connection string for a Neon database. All parameters are optional; the tool resolves the project, branch, and database automatically if not specified. Requires write access: the connection string carries a privileged role password, so it is unavailable in read-only mode. A read-only caller who needs a DATABASE\_URL must copy it from https://console.neon.tech manually.

- `projectId` (string, required)
  The ID of the project. If not provided, the only available project will be used.
- `branchId` (string, optional)
  The ID or name of the branch. If not provided, the default branch will be used.
- `computeId` (string, optional)
  The ID of the compute/endpoint. If not provided, the read-write compute associated with the branch will be used.
- `databaseName` (string, optional)
- `roleName` (string, optional)
  The name of the role to connect with. If not provided, the database owner name will be used.

### Errors

**default**
General Error.

The request may or may not be safe to retry, depending on the HTTP method, response status code,
and whether a response was received.

- If no response is returned from the API, a network error or timeout likely occurred.
- In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results.

The following HTTP methods are considered non-idempotent: `POST`, `PATCH`, `DELETE`, and `PUT`. Retrying these methods is generally **not safe**.
The following methods are considered idempotent: `GET`, `HEAD`, and `OPTIONS`. Retrying these methods is **safe** in the event of a network error or timeout.

Any request that returns a `503 Service Unavailable` response is always safe to retry.

Any request that returns a `423 Locked` response is safe to retry. `423 Locked` indicates that the resource is temporarily locked, for example, due to another operation in progress.

- `request_id` (string, optional)
  Unique identifier for the request, useful for debugging.
  You can set this value manually by including an `X-Request-ID` header in the request. If not provided, the value will be generated automatically.

- `code` (string, required)
  Machine-readable code classifying the error type. See `message` for a human-readable explanation.
  Default: \`\`

- `message` (string, required)
  Error message
