SmartTokenGuard

SmartTokenGuard is a remote MCP server: there is nothing to install. Its endpoint is https://stg-agent-560636228350.asia-east1.run.app/mcp, served over Streamable HTTP. In an assistant that accepts remote MCP servers (often under a setting named connectors, integrations or tools), add a new server and give it this URL; in a client configured by file, add it as a remote (HTTP) server with the same URL.

The registry entry declares an HTTP header for the connection: Authorization (required, secret). A secret header usually carries an API key or token issued by the service; clients that accept custom headers set it with the server's URL.

It can also run locally from an MCP Bundle: a single downloadable archive holding a local server and a manifest that describes it: https://github.com/nwjnjjj/smart-token-guard/releases/download/v1.2.2/smart-token-guard-1.2.2.mcpb version 1.2.2. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs a client that installs MCP Bundles; the file is opened in, or added to, that client. It reads the environment variable STG_LICENSE_KEY (required, secret); set it in the client's configuration for this server.

Derived from the registry entry; the live check above only shows whether the endpoint answered. What the server does, and on what terms, is set by its publisher; check its repository or website before giving it access to your accounts or files.
