alphavantage
Provides a Model Context Protocol (MCP) server that exposes Alpha Vantage stock/market data as MCP tools. Can run as an stdio MCP server (default) or as an HTTP “streamable” MCP server, with optional OAuth 2.1 protection for the HTTP mode. Uses an Alpha Vantage API key via environment variable `ALPHAVANTAGE_API_KEY`.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTP mode can be protected with OAuth 2.1 Bearer tokens, including JWT validation or token introspection. The README describes audience validation and secure session handling measures conceptually. TLS enforcement is assumed for typical HTTPS deployments (not explicitly stated in provided README). Alpha Vantage key is supplied via environment variable; however, explicit guidance about not logging secrets is not shown. Dependency hygiene cannot be verified from the provided content beyond listing dependencies.
⚡ Reliability
Best When
You want MCP tool access to Alpha Vantage data, and either (a) you run an MCP client that supports stdio or (b) you want an HTTP server with optional OAuth for protection.
Avoid When
You cannot or do not want to manage Alpha Vantage API keys, or you need guaranteed consistent throughput/uptime guarantees not documented in the provided materials.
Use Cases
- • Enable AI agents to query Alpha Vantage market data through MCP tools
- • Build Claude Desktop or other MCP-client workflows for stock/time-series data
- • Deploy as a lightweight service (HTTP streaming) or run locally via stdio
- • Add OAuth-protected access to the HTTP MCP server for multi-user/enterprise setups
- • Monitor tool-call metrics via Prometheus
Not For
- • High-scale production systems needing documented SLAs by provider (not indicated here)
- • Environments that cannot store/manage an external API key for Alpha Vantage
- • Clients that require a full REST/GraphQL/SDK interface rather than MCP
Interface
Authentication
OAuth is optional and applies to the HTTP streaming MCP server via `--oauth`. OAuth required scopes can be set with `OAUTH_REQUIRED_SCOPES` (e.g., `mcp:access mcp:read`). JWT validation and token introspection are both described, depending on env configuration.
Pricing
No pricing for the MCP server is stated in the provided content. Alpha Vantage has its own API key/pricing model (not detailed here). HTTP server is deployable on infra of your choosing.
Agent Metadata
Known Gotchas
- ⚠ Alpha Vantage API rate limits and response shapes are not described in the provided content; agent retries/rate handling may need to be implemented client-side depending on Alpha Vantage limits.
- ⚠ For HTTP mode, OAuth requires additional environment variables and proper client-side token handling (401/403, refresh flow).
- ⚠ Stdio vs HTTP: some MCP clients expect stdio; others can use the HTTP server. Ensure correct mode for the target MCP client.
