Claude

This page covers the supported BoldSign MCP Server setup paths for Claude Web, and Claude Code.

The hosted BoldSign MCP server is best connected to Claude Web as a remote connector. The OAuth authentication is the only supported method for this setup.

• Create or update a BoldSign OAuth application in the same region as your MCP endpoint.
• Anthropic documents https://claude.ai/api/mcp/auth_callback and https://claude.com/api/mcp/auth_callback as the hosted Claude redirect URIs for remote MCP authentication. Add these redirect URIs to your BoldSign OAuth application before you start the connector setup.
• Remote connector availability depends on the Claude plan and features available in your environment.

1. Open Claude Web and navigate from the sidebar Customize → Connectors.
2. Click + to add a custom connector.
3. Provide a name and the BoldSign MCP endpoint from Overview for your region.
4. Expand Advanced Settings, add the Client ID and Client Secret from your BoldSign OAuth application and Click Add.
5. Click "Connect" and complete the sign-in flow Claude presents for the connector.
6. Enable the connector for the conversation where you want to use BoldSign tools.

Claude Code supports remote HTTP MCP servers natively, making it a natural fit for the hosted BoldSign MCP server. The recommended approach uses an environment variable for the API key and a project-level .mcp.json file so the configuration is portable and the key is never stored in source control.

{
    "mcpServers": {
        "boldsign": {
            "type": "http",
            "url": "<YOUR_REGION_MCP_ENDPOINT>",
            "headers": {
                "X-API-Key": "${BOLDSIGN_API_KEY}"
            }
        }
    }
}

Replace <YOUR_REGION_MCP_ENDPOINT> with the endpoint for your region from the Regional Endpoints. The ${BOLDSIGN_API_KEY} placeholder is expanded from your shell environment at runtime, Claude Code does not store the literal key value.

After saving the file:

1. Start Claude Code in that project.
2. Open /mcp to confirm that the boldsign server connected and exposed tools.
3. Use a read-only prompt first to verify the connection.
