This one needs environment variables set before it will start: MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').). The author declared them in the registry entry; get the values from the project itself.

Attack Surface MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for Attack Surface MCP Server?

Attack Surface MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @cyanheads/attack-surface-mcp-server was installed 61 times last week.

How do I connect Attack Surface MCP Server?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @cyanheads/attack-surface-mcp-server straight from npm; nothing to host, nothing to sign up for.

How many people use Attack Surface MCP Server?

The npm package @cyanheads/attack-surface-mcp-server was installed 61 times in the last week. Week over week that is -4%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Attack Surface MCP Server open source?

Yes — it is published under the Apache-2.0 licence, written in TypeScript, 1 stars on GitHub and 6 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
