Claude Code

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.
