Whose server it is
  • Registry namecom.fedlin/fedlin-mcp-serververified in the MCP registry

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

Worth a look

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

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.

How to connect

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

{
  "mcpServers": {
    "fedlin-mcp-server": {
      "type": "http",
      "url": "https://mcp.fedlin.com/mcp"
    }
  }
}

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.
