Common questions
Is GetCurrentOffer safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: X-API-Key
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 7 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

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)
{"mcp": { "servers": { "getcurrentoffer": { "url": "https://getcurrentoffer.com/api/mcp", "headers": { "X-API-Key": "gco_your_api_key_here" } } } } }
Get a free API key at https://getcurrentoffer.com/api-keys.

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?"
