Nothing serious here today

Today is the operative word: we check qURL every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: QURL_API_KEY (API key for the qURL API with qurl:read, qurl:write, and/or qurl:resolve scopes. Obtain from https://layerv.ai.), QURL_API_URL (qURL API base URL. Defaults to https://api.layerv.ai. Override only for testing against a non-production qURL backend.), QURL_CONNECTOR_URL (Connector base URL used by local-file, file-data, and text-to-PDF upload tools before minting a qURL.), QURL_MCP_CONFIG (Optional path to a shared qURL MCP config file. Both stdio and HTTP modes can read SMTP, connector, and default API settings from this file.), MCP_MAX_UPLOAD_FILE_DATA_BYTES (Maximum decoded/local upload size. Accepts bytes or units such as 10mb; capped at 100mb.), QURL_SMTP_HOST (SMTP hostname for optional qURL link delivery.), QURL_SMTP_PORT (SMTP port for optional qURL link delivery.), QURL_SMTP_SECURE (Whether SMTP uses an implicit TLS connection (true/false).), QURL_SMTP_USERNAME (SMTP authentication username.), QURL_SMTP_PASSWORD (SMTP authentication password or app-specific credential.), QURL_SMTP_FROM_EMAIL (Validated sender email address for qURL delivery.), QURL_SMTP_FROM_NAME (Optional sender display name for qURL delivery.), QURL_SMTP_ALLOWED_RECIPIENTS (Optional comma-separated exact recipient allowlist.), QURL_SMTP_ALLOWED_RECIPIENT_DOMAINS (Optional comma-separated recipient-domain allowlist.), QURL_SMTP_MAX_RECIPIENTS_PER_MESSAGE (Maximum recipients in one delivery request (default 10).), QURL_SMTP_MAX_RECIPIENTS_PER_HOUR (Maximum attempted recipients per qURL key per fixed hourly window (default 100).). The author declared them in the registry entry; get the values from the project itself.

qURL — questions

Answers built from our own checks of this server.

Why is there no uptime for qURL?
qURL runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @layervai/qurl-mcp was installed 238 times last week.
How do I connect qURL?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @layervai/qurl-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use qURL?
The npm package @layervai/qurl-mcp was installed 238 times in the last week. Week over week that is +1086%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is qURL open source?
Yes — it is published under the MIT licence, written in TypeScript, 4 stars on GitHub and 21 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
