One key per organisation. We never store the secret half — only an sha256. Lose the key, rotate it from your dashboard.

Free tier issues a key instantly. For paid volume — see waitlist below.

Install in your client

Pick your environment. The config snippets below assume your tenant key is in the clipboard.

Friction-free first call — list tools to confirm auth works:

API="YOUR_ME_KEY"
curl -sH "Authorization: Bearer $API" -H "Content-Type: application/json" -X POST \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
  https://properfithire.co.uk/v1/mcp/ | python -m json.tool

Then call any tool with tools/call, e.g. verify_company with {"name_or_number":"12345678"}.

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS), ~/.config/Claude/claude_desktop_config.json (Linux), or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "mermoid-recruitment": {
      "url": "https://properfithire.co.uk/v1/mcp/",
      "headers": {
        "Authorization": "Bearer YOUR_ME_KEY"
      }
    }
  }
}

Two install routes — pick whichever you prefer:

A. One-line CLI (recommended):

claude mcp add mermoid-recruitment \
  --transport http \
  --url https://properfithire.co.uk/v1/mcp/ \
  --header "Authorization: Bearer YOUR_ME_KEY"

B. Edit ~/.claude.json manually:

{
  "mcpServers": {
    "mermoid-recruitment": {
      "type": "http",
      "url": "https://properfithire.co.uk/v1/mcp/",
      "headers": {
        "Authorization": "Bearer YOUR_ME_KEY"
      }
    }
  }
}

Open ~/.cursor/mcp.json (Linux/macOS) or %USERPROFILE%\.cursor\mcp.json (Windows). Create the file if it doesn't exist:

{
  "mcpServers": {
    "mermoid-recruitment": {
      "url": "https://properfithire.co.uk/v1/mcp/",
      "headers": {
        "Authorization": "Bearer YOUR_ME_KEY"
      }
    }
  }
}

Install the GitHub Copilot or Claude Dev extension, then settings.json:

"chat.mcp.servers": {
  "mermoid-recruitment": {
    "transport": {
      "type": "http",
      "url": "https://properfithire.co.uk/v1/mcp/"
    },
    "headers": {
      "Authorization": "Bearer YOUR_ME_KEY"
    }
  }
}

Use the official mcp client (or just requests):

import requests
KEY = "YOUR_ME_KEY"
def call(name, **args):
    r = requests.post("https://properfithire.co.uk/v1/mcp/",
        headers={"Authorization": f"Bearer {KEY}"},
        json={"jsonrpc":"2.0","id":1,"method":"tools/call",
              "params":{"name":name,"arguments":args}})
    r.raise_for_status()
    return r.json()["result"]

result = call("score_match", cv_text="...", jd_text="...")
print(result)
