1

Get your API key

Go to Settings → API & MCP Integration and click Generate API key. Your key starts with ssk_live_.

Copy the key immediately after generation — it will be partially masked afterwards. You can always regenerate it from Settings.

Add StackSpeed to Claude Desktop

Open your Claude Desktop config file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the StackSpeed server block (replacing ssk_live_your_key_here with your real key):

json
{
  "mcpServers": {
    "stackspeed": {
      "command": "npx",
      "args": ["-y", "@stackspeed/mcp"],
      "env": {
        "STACKSPEED_API_KEY": "ssk_live_your_key_here"
      }
    }
  }
}

Save the file and restart Claude Desktop.

Add StackSpeed to Cursor or Windsurf

In Cursor: open Settings → MCP Servers → Add Server. In Windsurf: open Settings → AI → MCP Servers.

Use the same JSON block as Claude Desktop:

json
{
  "mcpServers": {
    "stackspeed": {
      "command": "npx",
      "args": ["-y", "@stackspeed/mcp"],
      "env": {
        "STACKSPEED_API_KEY": "ssk_live_your_key_here"
      }
    }
  }
}

Try it out

Once configured, you can ask your AI tool questions like:

prompt
Which of these plugins would have the lowest performance impact?
- WooCommerce
- WPForms
- Yoast SEO
- W3 Total Cache

The AI will call StackSpeed's MCP tools to fetch real benchmark data and return a data-backed answer with sources.

Available MCP tools

search_pluginsSearch the plugin directory by name, category, or keyword
get_pluginFetch full benchmark data and metadata for a single plugin
simulate_stackSimulate a set of plugins and return a composite performance score
get_conflictsCheck a list of plugin slugs for known compatibility issues
compare_pluginsSide-by-side metric comparison for two specific plugins

Troubleshooting

The server shows "unauthorised" errors

Double-check your API key in Settings. If you recently regenerated it, make sure you updated the config file with the new key.

Claude Desktop doesn't show StackSpeed tools

Restart Claude Desktop after editing the config file. If it still doesn't appear, check the JSON is valid (no trailing commas) and the key is on a Paid or Premium plan.

npx fails with "package not found"

Make sure you have Node.js 18+ and npm 9+ installed. Run npm --version and node --version to check. The @stackspeed/mcp package requires Node 18.

MCP integration is available on Paid and Premium plans.
