PointsYeah MCP Server

Note: This package is part of the MCP Servers monorepo. For the latest updates and full source code, visit the PointsYeah MCP Server directory.

An MCP server for searching award flights and travel deals via PointsYeah. Search for flight availability using points and miles across 20+ airline loyalty programs and compare transfer options from major bank reward programs.

Features

• Award Flight Search - Search for flights using points/miles across multiple airline programs
• Bank Transfer Comparisons - See transfer options from Chase, Amex, Citi, Capital One, Bilt, and Wells Fargo
• Search History - Review your past award flight searches

Prerequisites

• A PointsYeah account (free or premium)
• Node.js 18+

Configuration

Environment Variables

Variable	Required	Description
POINTSYEAH_REFRESH_TOKEN	No	AWS Cognito refresh token from PointsYeah (optional — can be set at runtime via set_refresh_token tool)
ENABLED_TOOLGROUPS	No	Comma-separated tool groups to enable (default: all)

Authentication

All three tools are always visible to the MCP client. Auth-requiring tools (search_flights, get_search_history) return a clear error directing users to set_refresh_token when not authenticated.

• Without a token: Calling search_flights or get_search_history returns an error: "Authentication required. Please call the set_refresh_token tool first."
• After providing a valid token (via environment variable or the tool): Flight search tools work normally
• If the token expires or is revoked: Auth-requiring tools start returning errors again, prompting the user to call set_refresh_token

Obtaining the Refresh Token

• Go to PointsYeah Sign In and log in
• Open browser DevTools (F12) -> Console
• Run:

  document.cookie
    .split('; ')
    .find((c) => c.includes('.refreshToken='))
    .split('=')
    .slice(1)
    .join('=');
  

• Either set it as the POINTSYEAH_REFRESH_TOKEN environment variable, or provide it at runtime via the set_refresh_token tool

Note: The refresh token typically expires after 30-90 days. When it expires, the server will switch back to the set_refresh_token tool automatically.

Claude Desktop Configuration

Add to your Claude Desktop configuration file:

{
  "mcpServers": {
    "pointsyeah": {
      "command": "npx",
      "args": ["-y", "pointsyeah-mcp-server"],

  }
}

Manual Setup

# Clone the repository
git clone https://github.com/pulsemcp/mcp-servers.git
cd mcp-servers/experimental/pointsyeah

# Install dependencies
npm run install-all

# Set up environment
export POINTSYEAH_REFRESH_TOKEN="your-refresh-token"

# Build and run
npm run build
cd local && npm start

Available Tools

Tool	Description	Requires Auth
set_refresh_token	Set the PointsYeah refresh token for authentication	No
search_flights	Search for award flights using points/miles across multiple airline programs	Yes
get_search_history	Get past flight search history	Yes

Architecture

This server uses a two-step approach for flight searches:

• Explorer Search - HTTP POST to PointsYeah's explorer API with departure/arrival airports, date, and cabin classes. Returns summary results with CloudFront detail URLs.
• Detail Fetch - HTTP GET each detail URL to retrieve full route, segment, and transfer information. Up to 10 detail fetches per search.

All API calls use plain HTTP requests with the Cognito ID token for authentication.

Authentication Flow

PointsYeah uses AWS Cognito for authentication. The server supports dynamic authentication:

• On startup, if POINTSYEAH_REFRESH_TOKEN is set, validates it via Cognito. If valid, enters authenticated mode. If invalid/expired, enters unauthenticated mode.
• All tools are always registered. Auth-requiring tools check authentication state at call time and return errors when not authenticated.
• Once authenticated (via env var or set_refresh_token), exchanges the refresh token for access and ID tokens via Cognito's InitiateAuth API.
• Refreshes tokens lazily when they're within 5 minutes of expiry.
• If a token is revoked mid-session (detected via API error), automatically marks auth state as invalid so subsequent calls prompt re-authentication.

Development

# Install dependencies
npm run install-all

# Build
npm run build

# Run tests
npm test                    # Functional tests
npm run test:integration    # Integration tests (with TestMCPClient)
npm run test:all            # All tests

# Development mode
npm run dev

# Linting (from repo root)
cd ../.. && npm run lint
cd ../.. && npm run format

Limitations

• Refresh token expiry - The Cognito refresh token expires (typically 30-90 days). Users need to re-login and update the token.
• Free plan limits - PointsYeah may limit search frequency or result count on free plans.
• API changes - If PointsYeah changes their explorer API, the search flow may need updating.
