Claude says that a connector with this URL already exists. What should I do?

The connector is already added to your Claude account or organization. Open **Customize** > **Connectors** > **Yours** and find Renta. If the **Status** column shows **Connect**, click it and authorize access to your workspace.

Does the connector work in the Claude desktop app?

Yes. Custom connectors are available on claude.ai and in the Claude desktop app. The steps on this page apply to both.

How do I connect Claude Code?

Claude Code adds MCP servers from the terminal. Use the command from the [Renta MCP overview](/docs/mcp/).

Connect Renta MCP to Claude

Claude connects to the Renta MCP Server as a custom connector. After you add the connector, Claude calls Renta tools from your chats on claude.ai and in the Claude desktop app. It manages tracking plans, configures sources, destinations, and pipelines, and queries your data models.

Before you begin

Check the following before you add the connector.

A Renta account with a workspace.
During authorization, you select the workspace that Claude works with.
A Claude plan with custom connectors.
Custom connectors are available on the Free, Pro, Max, Team, and Enterprise plans. The Free plan allows one custom connector. For details, see Anthropic's guide to custom connectors.
Owner access on Team and Enterprise plans.
An owner adds the connector in Organization settings > Connectors. After that, each member clicks Connect next to Renta and signs in with their own Renta account.

Add Renta to Claude as a custom connector

Open the custom connector formStep 1

In the Claude sidebar, click Customize.
Open the Connectors tab.
Click Add, then select Add custom connector.

Tool permissions

Permissions define whether Claude calls a Renta tool without asking, asks you first, or never calls it. To open them, click Renta in the connectors list.

Claude splits Renta tools into two groups: Read-only tools and Write/delete tools. Set a permission for the whole group (1) or for a single tool (2).

Permission	What Claude does
Always allow	Calls the tool without asking.
Needs approval	Asks you to confirm each call.
Blocked	Does not call the tool.

Tools in the Write/delete tools group create, change, and delete objects in your Renta workspace and start pipeline runs. To confirm each of these calls yourself, set the group to Needs approval.

Claude lists tools by display name. The following table maps each name to the tool identifier used in the Renta MCP overview.

Name in Claude	Tool	Group
Semantic layer query	context_layer	Read-only tools
Customer 360 lookup	customer_360	Read-only tools
ETL connector catalogue	etl_connectors	Read-only tools
ETL field reference	etl_describe_fields	Read-only tools
ETL field value lookup	etl_field_values	Read-only tools
Operation schema lookup	renta_assistant	Read-only tools
Tracking plan data quality	tracking_plan_data_quality	Read-only tools
Bulk event changes	bulk_manage_events	Write/delete tools
Bulk property changes	bulk_manage_properties	Write/delete tools
Data models	manage_data_models	Write/delete tools
ETL destinations	manage_etl_destinations	Write/delete tools
ETL invite links	manage_etl_invite_links	Write/delete tools
ETL pipelines	manage_etl_pipelines	Write/delete tools
ETL pipeline runs	manage_etl_runs	Write/delete tools
ETL sources	manage_etl_sources	Write/delete tools
Events	manage_events	Write/delete tools

Use Renta in a chat

You turn connectors on and off for each chat. To check that Renta is on, follow these steps.

Open a new chat and click + below the message field.
Select Connectors.
Make sure the Renta toggle is on.

New chat in Claude with the plus menu open, the Connectors item, and the Renta toggle turned on

Then ask Claude a question that needs your Renta workspace. For example:

List my ETL pipelines and show the status of the last run for each.
Which events in my tracking plan had invalid hits over the last 7 days?
Show the data models available in Context Layer.

If a tool is set to Needs approval, Claude asks you to confirm the call before it runs.

Switch the workspace or disconnect

Claude works with the workspace you selected during authorization. The connection covers one workspace at a time.

Disconnect Renta.
Open Renta in Customize > Connectors > Yours and click Disconnect.
Switch to another workspace.
Disconnect Renta, click Connect, and select the other workspace on the Authorization request page.
