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.
Tools
Full input schemas live in mcp.json.
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" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
# 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:
-
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-Authenticateper RFC 9728, registers itself, then walks the user through a consent screen. No manual key copying. -
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_…orAuthorization: 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?"
