flyer MCP server

Which MCP servers are flyer'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.flingflyers/flingflyersverified in the MCP registry

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

  • Whether its tools do the product's job has not been judged yet.

Once connected

  • publish_flyer, update_flyer change data without a sign-in: anyone with the address can call them.

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.

What an agent can do with it

  • not sure · Send a live HTML or PDF file from an open browser tab
  • not sure · Pin a shared file on the server for up to 30 days
  • not sure · Share a file whose contents the server cannot read

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: publish_flyer, update_flyer

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 →

  • publish_flyer

    Publish an HTML document at a short public URL and return the link. Use this when the user wants to view a page you made in a real browser, send it to someone, or open it on another device — anywhere handing back raw markup is not good…

  • update_flyer

    Replace the contents of a flyer you already published, keeping the same URL. Use this for every revision to a page that is already live — a fix, a new section, a chart the user asked you to add — so the link they may have already sent to…

  • revoke_flyer

    Take down a flyer immediately: the link starts returning "gone" and the stored document is deleted. Needs the id and owner_token returned when it was published — there are no accounts, so that token is the only proof of ownership and it…

How to connect

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

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

Add it

Claude Code, in a terminal

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

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://flingflyers.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.
