Description

We are now hosting the official Alpha Vantage MCP server at https://mcp.alphavantage.co/, hence this PR to update the hosting URL.

Motivation and Context

The server remains unchanged. The hosting URL has changed. There are no breaking changes. The original configuration/URL will continue to work indefinitely.

How Has This Been Tested?

New and existing tests continue to pass on the new server URL.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Checklist

• I have read the MCP Protocol Documentation
• My changes follows MCP security best practices
• I have updated the server's README accordingly
• I have tested this with an LLM client
• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have documented all environment variables and configuration options

Additional context

This is a simple documentation change.

Could you link this to documentation with setup instructions for the remote server, instead of just the remote endpoint? Thanks!

Has docs

[olaservo]

Sorry, just saw that the url goes to setup instructions and not just the MCP endpoint. 👍

Yes, we confirm that the url serves as documentation purposes as well. Are we ready to merge this one? Thanks @olaservo!
