Our reading of CodexGuild, from the data

CodexGuild is a security MCP server, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

It runs either locally over stdio or as a hosted endpoint and needs one secret (CODEXGUILD_API_KEY); use a scoped, least-privilege key.

Install CodexGuild MCP server

claude mcp add codexguild -e CODEXGUILD_API_KEY='<codexguild-api-key>' -- npx -y @codexguild/mcp
