MCP Server Handbook
MCP Server Handbook 6 curated listings Disclosure-first directory

MCP SDKs and Tools

A focused directory for builders comparing protocol docs, server management, security scanners, and governance layers.

Directory policy

Listings are editorial unless explicitly labeled as sponsored. Paid or affiliate links should use the proper disclosure and link attributes before going live.

The goal here is to help builders compare options quickly and understand tradeoffs, not to create a vanity list of links.
