What this does
qURL exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
QURL_API_KEY QURL_API_URL QURL_CONNECTOR_URL QURL_LINK_HOSTS QURL_MCP_CONFIG MCP_MAX_UPLOAD_FILE_DATA_BYTES QURL_SMTP_HOST QURL_SMTP_PORT QURL_SMTP_SECURE QURL_SMTP_USERNAME QURL_SMTP_PASSWORD QURL_SMTP_FROM_EMAIL QURL_SMTP_FROM_NAME QURL_SMTP_ALLOWED_RECIPIENTS QURL_SMTP_ALLOWED_RECIPIENT_DOMAINS QURL_SMTP_MAX_RECIPIENTS_PER_MESSAGE QURL_SMTP_MAX_RECIPIENTS_PER_HOUR QURL_MCP_FEEDBACK
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
