Ask your agent who owns it, who controls it, and which rules apply.

Claude Code

claude mcp add --transport http tensorust https://shop.tensorust.com/api/mcp

Add --scope user to have it in every project. With a key:

claude mcp add --transport http tensorust https://shop.tensorust.com/api/mcp --header "Authorization: Bearer tdk_YOUR_KEY"

Claude (claude.ai and Claude Desktop)

Open Settings, then Connectors, and choose Add custom connector. Name it Tensorust, paste the URL below and leave the OAuth fields empty.

https://shop.tensorust.com/api/mcp

Custom connectors connect without a key, which gives the free tier.

ChatGPT

In Settings, open Apps and Connectors, then Advanced settings, and turn on Developer mode. Back in Apps and Connectors, choose Create, name it Tensorust, paste the URL, set Authentication to No authentication and confirm.

https://shop.tensorust.com/api/mcp

Developer mode connectors are added by URL and use the free tier.

Cursor

Or add it to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "tensorust": {
      "url": "https://shop.tensorust.com/api/mcp"
    }
  }
}

With a key:

{
  "mcpServers": {
    "tensorust": {
      "url": "https://shop.tensorust.com/api/mcp",
      "headers": {
        "Authorization": "Bearer tdk_YOUR_KEY"
      }
    }
  }
}

VS Code

Or put this in .vscode/mcp.json:

{
  "servers": {
    "tensorust": {
      "type": "http",
      "url": "https://shop.tensorust.com/api/mcp"
    }
  }
}

From a terminal:

code --add-mcp '{"name":"tensorust","type":"http","url":"https://shop.tensorust.com/api/mcp"}'

With a key (VS Code asks for it once and stores it as a secret):

{
  "inputs": [
    {
      "type": "promptString",
      "id": "tensorust-key",
      "description": "Tensorust key (tdk_...)",
      "password": true
    }
  ],
  "servers": {
    "tensorust": {
      "type": "http",
      "url": "https://shop.tensorust.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${input:tensorust-key}"
      }
    }
  }
}

Any other client or your own code

Any client that speaks Streamable HTTP can add the URL. Without a client, call a tool directly:

curl -s https://shop.tensorust.com/api/mcp \
  -H "content-type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"who_owns_home","arguments":{"address":"2746 Lofty Elm St","zip":"77038"}}}'

For full data, send Authorization: Bearer tdk_... on each request, or pass full: true and pay per call over x402 (below).
