Whose server it is
  • Addresshttps://mysal.life/mcpnot in the official registry: answered when asked

No entry in the official MCP registry names this server. It answered on mysal.life when the Atlas asked at the address servers are usually mounted on, so it is the vendor's own. Clients and catalogues that list servers from the registry do not show 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

None of the five warning signs in these definitions.

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 →

How to connect

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

{
  "mcpServers": {
    "mysal": {
      "type": "http",
      "url": "https://mysal.life/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http mysal https://mysal.life/mcp

Add to CursorAdd to VS Code

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