Alpha Vantage's free key covers equities, foreign exchange, crypto and a long catalogue of technical indicators, and this server, published on PyPI as alphavantage-mcp, puts that API behind MCP. It runs in three modes: plain stdio for desktop clients, streamable HTTP on a chosen port, and the same HTTP server with OAuth 2.1 in front of it. That third mode is what separates it from the usual single-user wrapper, since it publishes OAuth protected-resource metadata, validates bearer tokens by JWT signature or introspection endpoint, checks the token audience to block passthrough attacks and binds sessions to a user so a leaked session identifier is not enough on its own. For one desktop none of that applies and an ALPHAVANTAGE_API_KEY environment variable is the whole setup.
