FixedQR MCP server

Which MCP servers are FixedQR's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.fixedqr/fixedqrverified in the MCP registry

The registry name sits under fixedqr.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 51 ms.

  • Its tools do generate static QR codes for Wi-Fi, URLs and contact cards, but not add a logo to a code and keep it scannable; test codes with a phone camera before printing.
  • Checked on 1 of the 7 days it takes to judge reliability.

Once connected

  • For "generate static QR codes for Wi-Fi, URLs and contact cards", the likely first call is generate_qr.
  • create_dynamic_code, update_dynamic_code change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 3 of 3 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_dynamic_code, update_dynamic_code

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers3 tools · read 2026-10-27
  • generate_qr

    Generate a static QR code (never expires; content encoded directly, no redirect). Returns an image (PNG) or SVG text.

  • create_dynamic_code

    Create an editable (dynamic) QR code that redirects via fixedqr.com/r/<id>. Requires a FixedQR API key (Authorization: Bearer fq_...) and an active plan. The redirect keeps working even if the plan lapses.

  • update_dynamic_code

    Change the destination or label of an editable QR code you own. Requires a FixedQR API key and an active plan.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "fixedqr": {
      "type": "http",
      "url": "https://fixedqr.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http fixedqr https://fixedqr.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://fixedqr.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
