GetCurrentOffer MCP Server

Search live credit card merchant offers (cash back, points, statement credits) across Amex, Chase, Citi, PayPal, Rakuten, and Capital One — from any AI agent that speaks the Model Context Protocol.

GetCurrentOffer is a remote MCP server. There is nothing to install. Point your client at the endpoint, authenticate, and four tools are immediately available.

Quickstart

Claude Desktop

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

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

Restart Claude Desktop. The first call triggers an OAuth consent flow in your browser via Dynamic Client Registration — no API key needed.

Cursor / Windsurf / VS Code (Copilot Chat, Cline, Roo Code)

Try it from the command line

# Health check (no auth)
curl https://getcurrentoffer.com/api/mcp/health

# List tools (with API key)
curl -X POST https://getcurrentoffer.com/api/mcp \
  -H "Content-Type: application/json" \
  -H "X-API-Key: gco_your_api_key_here" \

# Search for Starbucks offers
curl -X POST https://getcurrentoffer.com/api/mcp \
  -H "Content-Type: application/json" \
  -H "X-API-Key: gco_your_api_key_here" \
  -d '{
    "jsonrpc": "2.0",
    "id": 2,
    "method": "tools/call",
    "params": {
      "name": "search_offers",
      "arguments": { "query": "Starbucks", "limit": 5 }
    }
  }'

Authentication

Two paths, both fully supported:

1. OAuth 2.1 with Dynamic Client Registration (RFC 7591) — recommended for hosted clients like Claude Desktop, ChatGPT connectors, and Claude.ai. The client discovers the auth server via the Protected Resource Metadata endpoint advertised in WWW-Authenticate per RFC 9728, registers itself, then walks the user through a consent screen. No manual key copying.

2. API key — recommended for CLI tools, server-side agents, and dev/test. Generate one at https://getcurrentoffer.com/api-keys and pass it via either X-API-Key: gco_… or Authorization: Bearer gco_…. Free tier available.

The Authorization Server Metadata and Protected Resource Metadata in this repo are static snapshots of the live well-known endpoints — fetch the live versions for the canonical source of truth.

Example prompts

• "Search for Nike credit card offers."
• "Compare offers for Starbucks across all my issuers."
• "List every merchant with an active Amex offer."
• "What dining offers are active on Chase right now?"
