Environment variables
  • QURL_API_KEYsecretOptional. Without it, the tools run through the local qURL CLI (qurl), which needs no account. With it, the tools use the qURL API: a key with qurl:read, qurl:write, and/or qurl:resolve scopes from https://layerv.ai.
  • QURL_API_URLqURL API base URL. Defaults to https://api.layerv.ai. Override only for testing against a non-production qURL backend.
  • MCP_MAX_UPLOAD_FILE_DATA_BYTESMaximum decoded/local upload size. Accepts bytes or units such as 10mb; capped at 100mb.
  • QURL_SMTP_USERNAMEsecretSMTP authentication username.
  • QURL_SMTP_PASSWORDsecretSMTP authentication password or app-specific credential.
  • QURL_SMTP_MAX_RECIPIENTS_PER_MESSAGEMaximum recipients in one delivery request (default 10).
  • QURL_SMTP_MAX_RECIPIENTS_PER_HOURMaximum attempted recipients per qURL key per fixed hourly window (default 100).
  • QURL_MCP_FEEDBACKSet to off to hide and disable outbound LayerV product feedback. Default on. Feedback is sent only by an explicit submit_feedback tool call.

HTML — for your website

Recommended. A dofollow link from your own domain is the one that counts for search engines, and it's the link we check for a free listing.

Markdown — for your README

[![qURL — listed on Serverdex](https://serverdex.io/brand/badge.svg)](https://serverdex.io/server/io-github-layervai-qurl-mcp?utm_source=badge)

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
