✅ Official Alpha Vantage MCP Server

A MCP server for the stock market data API, Alphavantage API.

MCP Server URL: https://mcp.alphavantage.co

Configuration

Getting an API Key

1. Sign up for a Free Alphavantage API key
2. Add the API key to your environment variables as ALPHAVANTAGE_API_KEY

Clone the project

git clone https://github.com/calvernaz/alphavantage.git

Server Modes

The AlphaVantage server can run in two different modes:

Stdio Server (Default)

This is the standard MCP server mode used for tools like Claude Desktop.

alphavantage
# or explicitly:
alphavantage --server stdio

Streamable HTTP Server

This mode provides real-time updates via HTTP streaming.

alphavantage --server http --port 8080

Streamable HTTP Server with OAuth 2.1 Authentication

This mode adds OAuth 2.1 authentication to the HTTP server, following the MCP specification for secure access.

alphavantage --server http --port 8080 --oauth

OAuth Configuration

When using the --oauth flag, the server requires OAuth 2.1 configuration via environment variables:

Required Environment Variables:

export OAUTH_AUTHORIZATION_SERVER_URL="https://your-auth-server.com/realms/your-realm"
export OAUTH_RESOURCE_SERVER_URI="https://your-mcp-server.com"

Optional Environment Variables:

# Token validation method (default: jwt)
export OAUTH_TOKEN_VALIDATION_METHOD="jwt"  # or "introspection"

# For JWT validation
export OAUTH_JWT_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----"
export OAUTH_JWT_ALGORITHM="RS256"  # default

# For token introspection validation
export OAUTH_INTROSPECTION_ENDPOINT="https://your-auth-server.com/realms/your-realm/protocol/openid-connect/token/introspect"
export OAUTH_INTROSPECTION_CLIENT_ID="your-client-id"
export OAUTH_INTROSPECTION_CLIENT_SECRET="your-client-secret"

# Optional: Required scopes (space-separated)
export OAUTH_REQUIRED_SCOPES="mcp:access mcp:read"

# Optional: Enable session binding for additional security (default: true)
export OAUTH_SESSION_BINDING_ENABLED="true"

OAuth Features

The OAuth implementation provides:

• OAuth 2.0 Protected Resource Metadata endpoint (/.well-known/oauth-protected-resource)
• Bearer token authentication for all MCP requests
• JWT and Token Introspection validation methods
• MCP Security Best Practices compliance:
  • Token audience validation (prevents token passthrough attacks)
  • Session hijacking prevention with secure session IDs
  • User-bound sessions for additional security
  • Proper WWW-Authenticate headers for 401 responses

Example: Keycloak Configuration

For testing with Keycloak:

# Keycloak OAuth configuration
export OAUTH_AUTHORIZATION_SERVER_URL="https://keycloak.example.com/realms/mcp-realm"
export OAUTH_RESOURCE_SERVER_URI="https://mcp.example.com"
export OAUTH_TOKEN_VALIDATION_METHOD="introspection"
export OAUTH_INTROSPECTION_ENDPOINT="https://keycloak.example.com/realms/mcp-realm/protocol/openid-connect/token/introspect"
export OAUTH_INTROSPECTION_CLIENT_ID="mcp-server"
export OAUTH_INTROSPECTION_CLIENT_SECRET="your-keycloak-client-secret"
export OAUTH_REQUIRED_SCOPES="mcp:access"

# Start server with OAuth
alphavantage --server http --port 8080 --oauth

OAuth Client Flow

When OAuth is enabled, MCP clients must:

1. Discover the authorization server via GET /.well-known/oauth-protected-resource
2. Register with the authorization server (if using Dynamic Client Registration)
3. Obtain access tokens from the authorization server
4. Include tokens in requests: Authorization: Bearer <access-token>
5. Handle 401/403 responses and refresh tokens as needed

Options:

• --server: Choose between stdio (default) or http server mode
• --port: Specify the port for the Streamable HTTP server (default: 8080)
• --oauth: Enable OAuth 2.1 authentication (requires --server http)

🚀 AWS Serverless Deployment

Deploy the AlphaVantage MCP Server on AWS Lambda using the stateless MCP pattern for production-ready, scalable deployment.

Quick AWS Deployment

cd deploy/aws-stateless-mcp-lambda
export ALPHAVANTAGE_API_KEY=your_api_key_here
./deploy.sh

Features:

• ✅ Stateless MCP pattern - Perfect for Lambda's execution model
• ✅ Auto-scaling - Handles any load with AWS Lambda + API Gateway
• ✅ Cost-effective - Pay only for requests (~$1-5/month for typical usage)
• ✅ Production-ready - Based on AWS official sample patterns
• ✅ OAuth 2.1 support - Optional authentication for secure access
