I Opened All Thirteen Memory MCP Servers. Every Public Signal I Trusted Was Wrong.

说明与用途

开发者常依赖星标、注册表条目和下载量等公开指标来评估内存 MCP 服务器，但这些指标往往无法准确反映实际安装的服务器。作者提出了四步快速检查：验证星标对应的仓库、主分支最近提交、README 中引用的子项目是否存在，以及“免费”方案的真实成本，从而快速判断服务器是否适合需求，避免误导性指标。

问题

Developers rely on public metrics (stars, registry entries, download counts, README claims) to evaluate memory MCP servers, but these signals often misrepresent the actual server being installed.

结果

Using the four quick checks eliminates reliance on misleading public signals, ensuring developers choose servers that match their deployment needs and avoid abandoned or misrepresented projects.

工作流

• Open the repository the install command points at to verify star count.
• Check the last commit date on the main branch.
• Search the repository to confirm the sub-project referenced in the README still exists.
• Determine what resources are required to run a “free” server (e.g., database, embeddings key).

证据

The star count often belongs to a different project

The registry is a form, not a review

Download counts measure the reference implementation, not the field
