Quick Start

1. Get your MCP Key

Sign up at apitier.com โ†’ Account โ†’ AI & MCP โ†’ Generate MCP Key.

Your MCP Key (mcp_...) automatically unlocks the tools for every APITier service you have subscribed to. No per-service configuration needed.


Hosted HTTP Endpoint

POST https://mcp.apitier.com/mcp?x-api-key=YOUR_MCP_KEY

Pass your MCP Key as the x-api-key query parameter. The endpoint resolves your subscribed services and returns only the tools available to you.

Required headers:

http
Content-Type: application/json
Accept: application/json, text/event-stream

Test with curl:

Terminal
curl -s -X POST 'https://mcp.apitier.com/mcp?x-api-key=YOUR_MCP_KEY' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | jq .

Call a tool:

Terminal
curl -s -X POST 'https://mcp.apitier.com/mcp?x-api-key=YOUR_MCP_KEY' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "verify_uk_company",
      "arguments": { "q": "03977902" }
    }
  }' | jq .

Health check:

Terminal
curl https://mcp.apitier.com/health

Use with any HTTP MCP client

config.json
{
  "mcpServers": {
    "apitier": {
      "url": "https://mcp.apitier.com/mcp?x-api-key=YOUR_MCP_KEY"
    }
  }
}

Claude Desktop (stdio)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

With MCP Key (recommended โ€” single key, all subscribed tools):

config.json
{
  "mcpServers": {
    "apitier": {
      "command": "npx",
      "args": ["-y", "@apitier/mcp-server"],
      "env": {
        "APITIER_MCP_KEY": "mcp_your-key-here"
      }
    }
  }
}

With individual service keys (if you prefer explicit control):

config.json
{
  "mcpServers": {
    "apitier": {
      "command": "npx",
      "args": ["-y", "@apitier/mcp-server"],
      "env": {
        "APITIER_POSTCODE_KEY":     "key-from-postcode-subscription",
        "APITIER_LEAD_AGENT_KEY":   "key-from-lead-agent-subscription",
        "APITIER_EMAIL_KEY":        "key-from-email-subscription",
        "APITIER_PHONE_KEY":        "key-from-phone-subscription",
        "APITIER_VAT_KEY":          "key-from-vat-subscription",
        "APITIER_BARCODE_KEY":      "key-from-barcode-subscription",
        "APITIER_CONVERT_DATA_KEY": "key-from-data-conversion-subscription"
      }
    }
  }
}

Restart Claude Desktop after saving. Only tools for your active subscriptions will appear.
