shield
About
Stdio MCP auth proxy: wrap any MCP server with per-tool permission enforcement.
Use this server
Add it to your MCP client. The catalogue lists this config verbatim from its source — it does not run, download, or vouch for the server. Review the command before you run it.
Transportstdio (runs a local command)
