Before you install Alpaca MCP Server

AgenticMart scanned Alpaca MCP Server on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
Based on its description and topics, it likely needs to touch financial accounts or data.

Before you install

Never give it live trading or payment keys until you've read the code.
Pin the version you reviewed instead of always installing the latest release.
Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.

Maintained by alpacahq on GitHub, 1,054 stars and 352 forks. Popularity is not proof of safety.
