Add dossaro to Claude

Open Claude's custom connector setup with the dossaro details prefilled, verify the standard safety notice and complete authorization.

On this page

Use the guided setup below to add dossaro as a custom connector in Claude. The button opens Claude with the connector name and MCP endpoint already filled in, so you only need to verify the details and approve the connection.

Claude will ask you to verify the connector

Because this setup is opened from an external link, Claude shows a standard safety reminder. This is expected, not an error. Before continuing, confirm that the prefilled values match the details below.

Connector name: dossaro
Connector URL: https://mcp.dossaro.com/mcp

Add to Claude

Claude opens in a new tab. After you add the connector, Claude will send you to dossaro to sign in and approve access.

Complete the connection

Select Add to Claude above.
Claude opens its Add custom connector dialog in a new tab.
When Claude shows the external-link safety reminder, confirm that the connector name is dossaro and the URL is https://mcp.dossaro.com/mcp.
Add the connector in Claude.
Sign in to dossaro when the authorization screen opens and approve access.
Return to Claude and start a new conversation with dossaro enabled.

The reminder is part of Claude's connector flow for details suggested by an external link. It asks you to check the prefilled name and URL before adding the connector; it does not mean the setup failed.

Manual setup

If the button does not open the dialog or the values are not prefilled, create the custom connector in Claude and enter:

text

Connector name: dossaro
Connector URL:  https://mcp.dossaro.com/mcp

After adding the connector, Claude will ask you to authorize dossaro. Sign in with your dossaro account and approve access.

What Claude gets

dossaro exposes read-only register and document research tools. It can search supported register sources, list public documents, parse document text where available and render research tables. It does not get your dossaro password or billing credentials.

See also: Research MCP reference for the tool list, source coverage and jurisdiction limits.

Troubleshooting

The connector details look different

Do not add the connector. Close the Claude dialog, return to this guide and reopen it with the Add to Claude button. Only continue when the name and URL exactly match the values shown above.

The authorization screen does not open

Remove the incomplete connector from Claude and add it again. Keep both the Claude tab and the dossaro authorization tab open until approval is complete.

The connector is not available in a conversation

Start a new conversation after completing authorization and make sure dossaro is enabled in Claude's connector controls. Workspace policy may restrict who can add custom connectors.
