Alpha Vantage MCP Server
Financial market data retrieval for LLMs using the Model Context Protocol.
Data last scanned last week · Reviewed last month
Overview
This MCP server provides LLMs and agentic workflows with direct access to real-time and historical stock market data from Alpha Vantage. It exposes financial data as tools that can be queried directly through compatible applications like Claude, Cursor, and VS Code. Users can connect via a remote server using OAuth for secure API key management or deploy a local instance using Python and the uv package. The server is designed to integrate into standard agentic development environments, facilitating automated analysis of financial datasets.
Our verdict
With a security score of 48/100, this server is classified as high-risk. This is primarily because the authentication methods and read-only tool implementations have not yet been editorially reviewed, and the project operates as a community-maintained repository rather than being managed directly by the official vendor. While it has zero direct dependencies and a active development history, users should exercise caution when inputting API keys, particularly when using legacy connection methods that embed keys in URLs.
- Zero direct dependencies reduces supply-chain attack surface
- Active development with commits recorded four days ago
- Open source MIT licensed codebase
- Not maintained by the official Alpha Vantage organization
- Authentication and read-only security logic not yet reviewed
- Lacks independent editorial security verification
